Product

Centered on supporting human experts' judgments

Your experts judge directly, quality is built into every step, every decision stays on the record, and Kili runs where your data has to stay.

Expert-in-the-Loop, Measured

Models produce outputs that look right, and only your experts can tell correct from plausible. Kili brings them into a designed review process and keeps the evidence of every call they make, so you can trust your AI and prove it.

Quality, Built In

Bad labels get caught at the step that produced them, not in a cleanup pass three weeks later. Quality is constructed while the work happens, and the reviewer has enough context to make the correction right the first time.

Know more

Auditable, from Day Zero

From the model's first prediction to the expert's final correction, Kili keeps every version of every judgment and the name behind it. Whether you're building training data or evaluating outputs, the record of how your data was made is there before anyone asks for it.

Know more

Deployment, Your Way

Where your data has to sit is a constraint, not a negotiation. Use Kili's cloud, keep your files in your own storage while you do, or run everything on your own Kubernetes, and size the infrastructure yourself from published requirements.

How can Kili support your use case

AI Evaluation Your Experts Stand Behind

A model that passes an automated benchmark can still be wrong in ways only your specialists would catch. Kili puts those specialists in charge of the verdict, scores how well they agree, and keeps the record, so you ship on evidence rather than on a leaderboard.

Post-Training Data Written by Your Experts

Post-training teaches a model to answer the way its examples answer, so the examples have to come from people who know the answer. Kili puts your specialists in charge of writing them, measures how well they agree before anything is exported, and runs wherever your data must stay.

Ensure Expert-quality Data Labeling

When the right class depends on a clinician, an imagery analyst or a quality engineer, a generalist produces labels that look finished and are wrong. Kili puts your specialists on the assets only they can call, checks their work while it happens, and keeps the record.
