2

Label

Vetted domain experts annotate to your guidelines across every modality.

3

Review

A human QA layer checks every submission before it ships.

Reviewer QA

Export

Download COCO, YOLO or custom formats, or pull via API — production-ready.

Trust & security

Your Data, Your Control, Your Competitive Edge

Enterprise-grade labeling shouldn't mean handing over your crown jewels.

Private & secure

Your data is siloed, access-controlled, and never used to train anyone else's models.

Human-in-the-loop

Real reviewers on every task — measurable accuracy, not black-box automation.

Your IP, your formats

Export exactly how your pipeline needs it. The output is yours, full stop.

FAQ

Everything you need to know

Do you keep my data private?+

Yes. Your data is siloed and access-controlled, never shared or used to train other models. Your IP and outputs remain entirely yours.

What modalities and formats do you support?+

Image, video, text, audio, document and 3D/point-cloud — 41 task types. Export COCO, YOLO or custom formats, or pull via API.

How do you ensure quality?+

Every submission passes a human QA review layer, with measurable accuracy, guideline adherence and edge-case checks before it ships.

How does pricing work?+

Transparent and usage-based — you pay per labeled unit at published per-task rates. Create a project and only pay for the work you label.

How do I get started?+

Create a client account, set up your project and labeling guidelines, and your tasks go to vetted annotators with a QA review layer. Export in your format when ready.

Ship better models with better data.
