Where CVAT Is Strong
Where Claru Is Different
Capture-first
Claru starts by capturing physical-world data instead of focusing only on labeling tools.
Enrichment layers
Depth, pose, and motion signals are generated as first-class outputs.
Robotics-ready delivery
Claru ships datasets in formats that plug directly into robotics stacks.

Claru captures new physical-world data tailored to robotics tasks.
Where each wins
CVAT is strong when you need a flexible open-source labeling stack.
Claru is stronger when capture and enrichment are the bottleneck.
When CVAT Is a Fit
- You need an open-source annotation platform for CV data.
- You want flexible tools for images, video, and 3D labeling.
- You already have data and need annotation workflows.
When Claru Is a Fit
- You need physical-world data captured for robotics tasks.
- You want enrichment layers like depth, pose, and motion signals.
- You need datasets delivered in robotics-native formats.
How Claru Delivers Physical AI Data
Claru provides an end-to-end pipeline so physical AI teams can move from brief to training-ready data quickly.
Scope the Dataset
Define the target behaviors, environments, and label schema with your research team. We align on formats, enrichment layers, and success criteria before capture begins.
Capture Real-World Data
Activate the collector network, teleoperation runs, or game-based capture to gather the exact clips your model needs.
Enrich Every Clip
Generate depth maps, pose, segmentation, and optical flow in batch. Cross-validate signals to ensure aligned training inputs.
Expert Annotation
Specialized annotators label action boundaries, affordances, and intent using project-specific guidelines and QA checks.
Deliver Training-Ready
Ship datasets in WebDataset, HDF5, RLDS, or your native format with manifests, checksums, and datasheets.
Claru by the Numbers
