What iSAHIT Is Built For

iSAHIT positions itself as a Human-by-API partner for AI data projects, delivering managed labeling capacity across computer vision, natural language processing, and reinforcement learning from human feedback workflows. The platform supports bounding boxes, polygons, semantic segmentation, text classification, sentiment analysis, and conversational AI evaluation tasks^[1]. iSAHIT emphasizes ethical workforce practices, employing women across four continents and maintaining B Corp certification.

The service model is annotation-centric: clients upload images, text, or audio; annotators apply labels; quality-control layers validate outputs. iSAHIT offers flexible tooling integration, allowing teams to use proprietary annotation interfaces, partner platforms like Labelbox, or iSAHIT's native environment. This approach works well for static datasets where the bottleneck is human judgment at scale — labeling millions of web images, ranking LLM responses, or transcribing speech corpora.

For physical AI, the workflow inverts: the bottleneck is capture, not labeling. Robotics models need real-world teleoperation trajectories, multi-modal sensor streams (RGB-D, LiDAR, IMU, force-torque), and embodied context (gripper state, joint angles, contact events) that annotation-only platforms cannot generate^[2]. DROID contains 76,000 manipulation trajectories across 564 skills and 86 environments; no amount of crowd labeling can synthesize that diversity from scratch. iSAHIT's strength is enriching existing data; Truelabel's strength is creating the data robotics teams need.

Company Snapshot: iSAHIT at a Glance

iSAHIT operates as a managed annotation service with a distributed workforce model. The company highlights ethical labor practices, transparent pricing, and multi-continent coverage to ensure 24-hour turnaround cycles. Core verticals include computer vision (object detection, instance segmentation, keypoint annotation), NLP (named entity recognition, intent classification, text summarization), and RLHF (preference ranking, response evaluation, safety alignment).

The platform integrates with Labelbox, V7, and CVAT for annotation workflows, allowing clients to maintain existing toolchains while outsourcing labeling capacity. iSAHIT does not manufacture training data — it processes data clients already possess. For teams building vision transformers on ImageNet-scale corpora or fine-tuning LLMs with human preference signals, this model delivers cost-effective scale.

Physical AI buyers face a different constraint set. Open X-Embodiment aggregated 22 datasets spanning 527 skills and 160,000 tasks, but procurement teams still report gaps in long-horizon manipulation, outdoor navigation, and multi-robot coordination scenarios. The limiting factor is data existence, not labeling throughput. Truelabel's marketplace connects buyers with 12,000 collectors who capture domain-specific scenarios — warehouse pick-and-place, kitchen assembly, outdoor traversal — then apply expert enrichment layers (grasp quality scores, collision proximity masks, terrain traversability maps) that annotation-only workflows cannot produce^[3].

Key Claims: iSAHIT's Positioning

iSAHIT markets itself on four pillars: human-by-API delivery, multi-modal HITL, RLHF workflows, and ethical workforce practices. The human-by-API claim positions labeling as an on-demand service layer, abstracting workforce management behind API endpoints. Multi-modal HITL spans image, video, text, audio, and speech, covering the input modalities common in web-scale AI training. RLHF workflows target LLM fine-tuning, where human evaluators rank model outputs to align behavior with safety and helpfulness criteria.

The ethical workforce model emphasizes fair wages, transparent contracts, and gender diversity. iSAHIT reports employing women across Africa, Asia, Europe, and the Americas, with B Corp certification validating social impact metrics. For enterprises with ESG reporting requirements, this positioning offers compliance value beyond annotation quality.

Physical AI introduces orthogonal requirements. RT-1 trained on 130,000 demonstrations across 700 tasks, but the dataset's value derives from embodied diversity — different robots, grippers, objects, lighting, and failure modes — not labeling density. BridgeData V2 contains 60,000 trajectories with language annotations, but the language was recorded during teleoperation, not applied post-hoc by crowd workers. Truelabel's collectors wear egocentric cameras and haptic gloves during task execution, capturing intent signals (gaze, grip force, hesitation) that retrospective annotation cannot reconstruct. The ethical dimension shifts from labor fairness to data provenance: ensuring collectors consent to commercial use, datasets carry verified lineage, and licensing terms permit model deployment^[4].

Where iSAHIT Is Strong

iSAHIT excels in three scenarios: high-volume 2D annotation, RLHF preference collection, and flexible tooling integration. For computer vision teams labeling millions of web images with bounding boxes, polygons, or semantic masks, iSAHIT's distributed workforce delivers cost-effective throughput. The platform supports CVAT polygon workflows and integrates with Labelbox's model-assisted labeling, reducing per-image costs when pre-trained models provide initial predictions.

RLHF workflows benefit from iSAHIT's multi-continent coverage, enabling 24-hour evaluation cycles for LLM fine-tuning. Annotators rank chatbot responses, flag unsafe outputs, and score helpfulness across conversational turns. This human-in-the-loop feedback loop is critical for aligning foundation models with user preferences, a task that cannot be automated without sacrificing safety guarantees.

Flexible tooling integration allows enterprises to maintain proprietary annotation pipelines while outsourcing capacity. Teams using V7's workflow automation or Dataloop's data management can route labeling tasks to iSAHIT without migrating datasets or retraining annotators. For organizations with established MLOps stacks, this interoperability reduces switching costs.

Physical AI teams need data creation, not just labeling. RoboNet aggregated 15 million frames from seven robot platforms, but the dataset's utility stems from trajectory diversity — different manipulation strategies, recovery behaviors, and environmental interactions — not annotation density. Truelabel's collectors execute tasks in real environments, capturing sensor streams (RGB-D, LiDAR, IMU, force-torque) and embodied metadata (joint states, contact events, grasp stability) that crowd workers cannot synthesize from static images^[2].

Where Truelabel Is Different

Truelabel operates as a capture-first marketplace, not an annotation service. The platform's 12,000 collectors use wearable sensors, depth cameras, and force-torque arrays to record real-world task execution — warehouse navigation, kitchen assembly, outdoor traversal, multi-object manipulation. Every clip arrives with multi-modal enrichment: depth maps, semantic segmentation masks, grasp quality scores, trajectory metadata, and collision proximity annotations. Buyers receive training-ready datasets in RLDS, MCAP, and HDF5 formats, eliminating the six-month preprocessing lag common in annotation-only workflows^[3].

The marketplace model solves data scarcity, not labeling throughput. DROID required 18 months and 86 environments to capture 76,000 trajectories; Truelabel's distributed collector network parallelizes capture across geographies, reducing time-to-dataset from quarters to weeks. Collectors specialize in domain verticals — one cohort focuses on kitchen tasks with Claru's kitchen dataset templates, another on warehouse logistics with AMR navigation scenarios, a third on outdoor manipulation with uneven terrain and variable lighting.

Enrichment layers go beyond bounding boxes. Truelabel's expert annotators apply grasp stability scores (force-torque analysis), collision proximity masks (depth-based safety margins), terrain traversability maps (LiDAR-derived slope and roughness), and semantic action labels (pick, place, push, pull, rotate). Open X-Embodiment demonstrated that cross-embodiment transfer improves when datasets share semantic action vocabularies; Truelabel's annotation schema aligns with RT-X taxonomies, ensuring compatibility with OpenVLA and other foundation models.

Provenance is cryptographically verified. Every dataset carries collector consent records, sensor calibration logs, and licensing terms in machine-readable formats. Buyers know who captured what, when, where, and under what terms — critical for EU AI Act compliance, model audits, and commercial deployment risk management^[4].

Turnaround: iSAHIT quotes 24-72 hours for labeling tasks; Truelabel's capture-to-delivery cycle runs 2-6 weeks depending on scenario complexity. Pricing model: iSAHIT charges per annotation unit (image, text snippet, audio clip); Truelabel prices per trajectory or per dataset, with enrichment layers bundled.

Integration: iSAHIT plugs into Labelbox, V7, and CVAT; Truelabel exports to LeRobot, TensorFlow RLDS, and PyTorch dataloaders. Use case fit: iSAHIT suits web-scale vision and NLP projects with existing data; Truelabel suits robotics teams building manipulation, navigation, or embodied AI models from scratch^[3].

Deep Dive: Services vs Pipeline

iSAHIT's service model abstracts workforce management: clients define annotation schemas, upload data batches, and receive labeled outputs via API. The platform handles annotator recruitment, training, quality control, and payment processing. For enterprises with fluctuating labeling demand, this on-demand capacity avoids the overhead of maintaining in-house annotation teams. iSAHIT's multi-continent workforce enables 24-hour turnaround by routing tasks across time zones.

The service model assumes data already exists. Clients must capture images, record audio, or collect text before iSAHIT can add value. For web-scale AI, this assumption holds: ImageNet, Common Crawl, and YouTube provide abundant raw data. For physical AI, the assumption breaks: Open X-Embodiment aggregated 22 datasets, but procurement teams still report gaps in long-horizon tasks, outdoor scenarios, and multi-robot coordination.

Truelabel inverts the workflow: capture precedes enrichment. Collectors execute tasks in real environments, recording RGB-D streams, LiDAR scans, IMU traces, and force-torque signals. Expert annotators then apply domain-specific enrichment — grasp quality scores for manipulation, terrain traversability maps for navigation, collision proximity masks for safety-critical scenarios. The output is a training-ready dataset, not a labeled image set.

This pipeline model suits robotics buyers who need data that does not yet exist. DROID required custom teleoperation rigs, 86 environments, and 18 months to capture 76,000 trajectories. Truelabel's distributed collector network parallelizes capture, reducing time-to-dataset from quarters to weeks. Buyers specify task requirements (pick-and-place in cluttered bins, outdoor navigation on gravel, bimanual assembly), and collectors execute scenarios with calibrated sensors and verified consent^[3].

Deep Dive: Modalities and Task Coverage

iSAHIT's modality coverage spans 2D images, video, text, audio, and speech. Computer vision tasks include bounding boxes, polygons, semantic segmentation, keypoint annotation, and video object tracking. NLP tasks cover named entity recognition, intent classification, sentiment analysis, text summarization, and conversational AI evaluation. RLHF workflows support preference ranking, response scoring, and safety flagging for LLM fine-tuning.

These modalities align with web-scale AI training: Labelbox reports 80 percent of annotation demand comes from 2D vision tasks, and Scale AI built its data engine on image and text labeling before expanding to physical AI. For teams training vision transformers, object detectors, or language models, iSAHIT's modality mix matches training data requirements.

Physical AI demands embodied modalities: RGB-D streams, LiDAR point clouds, IMU traces, force-torque signals, joint angle trajectories, and egocentric video. RT-1 trained on 130,000 demonstrations with language annotations, but the dataset's value derives from multi-modal sensor fusion — correlating gripper force with object slip, aligning depth maps with collision events, synchronizing IMU data with navigation failures. Annotation-only platforms cannot synthesize these correlations from static images.

Truelabel's collectors capture synchronized sensor streams in real-world environments. A warehouse navigation dataset includes RGB-D video, LiDAR scans, IMU traces, wheel odometry, and semantic action labels (approach, grasp, transport, release). A kitchen manipulation dataset adds force-torque signals, gripper state, and egocentric video with gaze tracking. Expert annotators enrich streams with depth-based collision masks, grasp stability scores, and terrain traversability maps. The output is a multi-modal training corpus ready for LeRobot diffusion policies or OpenVLA vision-language-action models^[3].

Deep Dive: Data Sourcing and Provenance

iSAHIT's data sourcing model is client-driven: buyers upload datasets, define annotation schemas, and receive labeled outputs. The platform does not generate training data — it processes data clients already possess. For web-scale AI, this model works: enterprises scrape web images, record user interactions, or license stock footage, then route labeling to iSAHIT's workforce.

Physical AI introduces data scarcity. Open X-Embodiment aggregated 22 datasets, but procurement teams report gaps in outdoor navigation, long-horizon manipulation, and multi-robot coordination. The bottleneck is capture, not labeling. DROID required 18 months and 86 environments to record 76,000 trajectories; no annotation service can synthesize that diversity from scratch.

Truelabel's marketplace solves data scarcity with distributed capture. The platform's 12,000 collectors execute tasks in real environments — warehouses, kitchens, outdoor terrains, industrial facilities — using wearable sensors, depth cameras, and force-torque arrays. Collectors specialize in domain verticals: one cohort focuses on kitchen tasks, another on warehouse logistics, a third on outdoor manipulation. Buyers specify task requirements, and collectors execute scenarios with calibrated sensors and verified consent.

Provenance is cryptographically verified. Every dataset carries collector consent records, sensor calibration logs, and licensing terms in machine-readable formats. Buyers know who captured what, when, where, and under what terms — critical for GDPR consent requirements, EU AI Act compliance, and commercial deployment risk management. Truelabel's provenance layer uses C2PA content credentials to embed metadata in dataset files, ensuring auditability across the model training lifecycle^[4].

Deep Dive: Robotics-Ready Delivery Formats

iSAHIT delivers labeled datasets in standard annotation formats: COCO JSON for object detection, Pascal VOC XML for segmentation, CSV for text classification, and proprietary JSON schemas for RLHF rankings. These formats suit web-scale AI training pipelines, where dataloaders parse annotations into tensors for model ingestion. Labelbox and V7 export similar formats, ensuring interoperability across annotation platforms.

Robotics training requires trajectory formats that encode temporal dependencies, multi-modal sensor streams, and embodied metadata. RLDS (Reinforcement Learning Datasets) structures episodes as sequences of observations, actions, rewards, and metadata, with support for nested dictionaries and variable-length trajectories. MCAP stores ROS bag data with efficient indexing and compression, enabling fast random access to multi-sensor streams. HDF5 provides hierarchical storage for large arrays, commonly used in BridgeData V2 and DROID.

Truelabel delivers datasets in robotics-native formats. A manipulation dataset exports as RLDS episodes with RGB-D observations, joint angle actions, gripper state, force-torque signals, and semantic action labels. A navigation dataset ships as MCAP bags with LiDAR scans, IMU traces, wheel odometry, and terrain traversability maps. Buyers load datasets directly into LeRobot training scripts or TensorFlow RLDS pipelines without format conversion.

Enrichment layers are embedded in trajectories. Depth maps align with RGB frames via calibrated camera intrinsics. Grasp quality scores annotate gripper closure events. Collision proximity masks mark safety-critical timesteps. Semantic action labels follow Open X-Embodiment taxonomies, ensuring compatibility with RT-X models and OpenVLA. The output is a training-ready corpus that eliminates the six-month preprocessing lag common in annotation-only workflows^[3].

When iSAHIT Is a Fit

iSAHIT suits three buyer profiles: web-scale vision teams with existing image datasets, LLM developers running RLHF fine-tuning loops, and enterprises with established annotation toolchains. For computer vision teams labeling millions of web images with bounding boxes or semantic masks, iSAHIT's distributed workforce delivers cost-effective throughput. The platform's integration with Labelbox and CVAT allows teams to maintain existing pipelines while outsourcing capacity.

LLM developers benefit from iSAHIT's RLHF workflows, where annotators rank chatbot responses, flag unsafe outputs, and score helpfulness across conversational turns. Multi-continent coverage enables 24-hour evaluation cycles, accelerating fine-tuning iterations. For foundation model teams aligning GPT-scale models with user preferences, this human-in-the-loop feedback is irreplaceable.

Enterprises with proprietary annotation tools value iSAHIT's flexible integration. Teams using V7's workflow automation or Dataloop's data management can route labeling tasks to iSAHIT without migrating datasets or retraining annotators. For organizations with established MLOps stacks, this interoperability reduces switching costs and accelerates deployment.

Physical AI teams face different constraints. RT-1 trained on 130,000 demonstrations, but the dataset's value derives from embodied diversity — different robots, grippers, objects, lighting, and failure modes — not labeling density. Annotation-only platforms cannot synthesize this diversity from static images. Robotics buyers need capture-first workflows that generate multi-modal sensor streams in real-world environments^[2].

When Truelabel Is a Fit

Truelabel suits robotics teams building manipulation models, navigation systems, or embodied AI agents from scratch. Buyers who need teleoperation trajectories, multi-modal sensor streams, or domain-specific scenarios (warehouse logistics, kitchen assembly, outdoor traversal) benefit from Truelabel's capture-first marketplace. The platform's 12,000 collectors execute tasks in real environments, recording RGB-D video, LiDAR scans, IMU traces, force-torque signals, and egocentric streams with wearable sensors.

Teams training vision-language-action models like OpenVLA or diffusion policies via LeRobot need datasets with semantic action labels, language annotations, and multi-modal observations. Truelabel's expert annotators apply RT-X-compatible action taxonomies, ensuring cross-embodiment transfer. Open X-Embodiment demonstrated that shared semantic vocabularies improve generalization; Truelabel's annotation schema aligns with this standard.

Buyers with compliance requirements value Truelabel's provenance layer. Every dataset carries cryptographically signed collector consent, sensor calibration logs, and licensing terms in machine-readable formats. For EU AI Act compliance, model audits, or commercial deployment risk management, this verified lineage is non-negotiable. GDPR Article 7 requires explicit consent for data processing; Truelabel's consent records satisfy this requirement.

Teams facing data scarcity benefit from Truelabel's distributed collector network. DROID required 18 months to capture 76,000 trajectories; Truelabel parallelizes capture across geographies, reducing time-to-dataset from quarters to weeks. Buyers specify task requirements (pick-and-place in cluttered bins, outdoor navigation on gravel, bimanual assembly), and collectors execute scenarios with calibrated sensors and verified consent^[3].

How Truelabel Delivers Physical AI Data

Truelabel's workflow begins with request intake: buyers specify task requirements, sensor modalities, environment constraints, and enrichment layers. A warehouse navigation request might request 5,000 trajectories with RGB-D video, LiDAR scans, IMU traces, and terrain traversability maps. A kitchen manipulation request might require 2,000 pick-and-place demonstrations with force-torque signals, grasp quality scores, and egocentric video.

Collectors execute tasks in real environments using calibrated sensor rigs. A manipulation collector wears haptic gloves, an egocentric camera, and operates a robot arm with force-torque sensors. A navigation collector mounts RGB-D cameras, LiDAR, and IMU on a mobile platform. Collectors follow task protocols (approach object, grasp, transport, release) while sensors record synchronized streams. Every session includes calibration checks and consent verification.

Expert annotators apply multi-layer enrichment. Depth maps align with RGB frames via camera intrinsics. Semantic segmentation masks identify objects, surfaces, and obstacles. Grasp quality scores analyze force-torque signals during gripper closure. Collision proximity masks mark safety-critical timesteps. Terrain traversability maps derive from LiDAR-based slope and roughness analysis. Semantic action labels follow Open X-Embodiment taxonomies.

Datasets export in robotics-native formats: RLDS episodes with nested observations and actions, MCAP bags with indexed multi-sensor streams, or HDF5 hierarchies with trajectory metadata. Buyers load datasets directly into LeRobot training scripts or TensorFlow RLDS pipelines. Provenance metadata embeds via C2PA content credentials, ensuring auditability across the model training lifecycle^[3].

Truelabel by the Numbers

Truelabel's marketplace operates with 12,000 active collectors across six continents, specializing in domain verticals from warehouse logistics to outdoor manipulation. The platform has delivered 340 datasets spanning manipulation, navigation, teleoperation, and multi-robot coordination scenarios. Collector rigs capture 18 sensor modalities including RGB-D, LiDAR, IMU, force-torque, wheel odometry, joint angles, gripper state, and egocentric video with gaze tracking.

Enrichment layers include depth maps (aligned via calibrated camera intrinsics), semantic segmentation masks (object, surface, obstacle classes), grasp quality scores (force-torque analysis), collision proximity masks (depth-based safety margins), terrain traversability maps (LiDAR-derived slope and roughness), and semantic action labels (RT-X-compatible taxonomies). Datasets export in RLDS, MCAP, and HDF5 formats, with provenance metadata embedded via C2PA content credentials.

Turnaround times run 2-6 weeks from request intake to delivery, depending on scenario complexity and trajectory count. A 1,000-trajectory kitchen manipulation dataset with RGB-D, force-torque, and grasp annotations ships in 3 weeks. A 5,000-trajectory warehouse navigation dataset with LiDAR, IMU, and terrain maps ships in 5 weeks. Pricing scales per trajectory or per dataset, with enrichment layers bundled.

Buyers include robotics startups training OpenVLA-based manipulation policies, autonomous vehicle teams building NVIDIA Cosmos world models, and industrial automation vendors deploying Universal Robots collaborative arms. Truelabel's provenance layer satisfies GDPR consent requirements and EU AI Act compliance, enabling commercial deployment without legal risk^[3].

Other Alternatives Worth Considering

Beyond iSAHIT and Truelabel, physical AI buyers evaluate Scale AI, Appen, CloudFactory, and Sama for annotation capacity, and Labelbox, V7, Encord, and Segments.ai for tooling. Scale AI expanded its data engine to physical AI in 2024, partnering with Universal Robots to capture manipulation demonstrations. The platform offers managed annotation services with robotics-aware quality control, but pricing targets enterprise budgets and minimum commitments start at six figures.

Appen and Sama provide crowd-sourced labeling for computer vision and NLP tasks, with global workforce coverage and 24-hour turnaround. Both platforms support bounding boxes, polygons, and semantic segmentation, but neither offers robotics-specific enrichment (grasp scores, collision masks, terrain maps). For teams with existing datasets needing human labels, these platforms deliver cost-effective scale.

Labelbox, V7, and Encord offer annotation tooling with model-assisted labeling, workflow automation, and data management. Encord raised 60 million in Series C to expand multi-modal annotation for autonomous vehicles and robotics. Segments.ai specializes in point cloud labeling for LiDAR datasets, supporting PointNet-based segmentation and 3D bounding boxes.

For buyers needing capture-first workflows, Truelabel remains the only marketplace with distributed collector networks, multi-modal sensor rigs, and robotics-native delivery formats. DROID and BridgeData V2 demonstrate the value of real-world teleoperation data, but academic labs lack the infrastructure to parallelize capture at commercial scale. Truelabel's 12,000 collectors execute tasks across geographies, reducing time-to-dataset from quarters to weeks^[3].

How to Choose Between iSAHIT and Truelabel

Choose iSAHIT if you have existing datasets (images, text, audio) and need human-in-the-loop labeling at scale. The platform suits web-scale vision teams running bounding-box annotation on millions of images, LLM developers collecting RLHF preference rankings, or enterprises with established annotation toolchains seeking outsourced capacity. iSAHIT's multi-continent workforce, flexible tooling integration, and ethical labor practices deliver cost-effective throughput for annotation-centric workflows.

Choose Truelabel if you need physical AI training data that does not yet exist. The platform suits robotics teams building manipulation models, navigation systems, or embodied AI agents from scratch. Truelabel's 12,000 collectors capture real-world teleoperation trajectories, multi-modal sensor streams (RGB-D, LiDAR, IMU, force-torque), and domain-specific scenarios (warehouse logistics, kitchen assembly, outdoor traversal). Expert annotators apply robotics-specific enrichment (grasp scores, collision masks, terrain maps), and datasets export in RLDS, MCAP, and HDF5 formats ready for LeRobot or OpenVLA training.

The decision hinges on data existence. If your bottleneck is labeling throughput on existing data, iSAHIT delivers managed annotation services. If your bottleneck is data scarcity — you need trajectories, sensor streams, or embodied scenarios that no public dataset provides — Truelabel's capture-first marketplace solves the procurement problem. Open X-Embodiment aggregated 22 datasets, but procurement teams still report gaps in long-horizon tasks, outdoor scenarios, and multi-robot coordination. Truelabel's distributed collector network fills those gaps with verified provenance and commercial licensing^[3].
