▋
Build production-grade training data with complete control. Your Data, Your Control, Your Competitive Edge
Solutions
From RLHF and reasoning to image, video and multilingual annotation — expert humans in the loop, QA-reviewed on every task.
Boxes, polygons, segmentation, keypoints and tracking — pixel-perfect, reviewed.
Pairwise & multi-response ranking, SFT, red-teaming, factuality and quality rating.
Every submission passes a reviewer layer — measurable accuracy, not a black box.
Human evaluation, A/B testing and factuality scoring to measure real model quality.
Domain specialists for medical, legal, code and financial data — expert-grade quality.
Image, video, text and audio — including OCR, transcription and translation.
How it works
Bring your dataset and spec via UI or API — enterprise-grade security by default.
Vetted domain experts annotate to your guidelines across every modality.
A human QA layer checks every submission before it ships.
Reviewer QADownload COCO, YOLO or custom formats, or pull via API — production-ready.
Trust & security
Enterprise-grade labeling shouldn't mean handing over your crown jewels.
Your data is siloed, access-controlled, and never used to train anyone else's models.
Real reviewers on every task — measurable accuracy, not black-box automation.
Export exactly how your pipeline needs it. The output is yours, full stop.
Loved by AI teams
“The QA layer is the difference. Our model accuracy jumped once we switched — labels we could actually trust in production.”
“Domain experts on medical imaging, delivered fast and secure. Exactly the control we needed for regulated data.”
“Started self-serve for a pilot, scaled to a managed team in a week. Transparent pricing, no lock-in.”
Get started
Launch a project yourself in minutes — you only pay for the work you label.
FAQ
Yes. Your data is siloed and access-controlled, never shared or used to train other models. Your IP and outputs remain entirely yours.
Image, video, text, audio, document and 3D/point-cloud — 41 task types. Export COCO, YOLO or custom formats, or pull via API.
Every submission passes a human QA review layer, with measurable accuracy, guideline adherence and edge-case checks before it ships.
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.
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.
