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.

*No credit card required. Risk-free evaluation.

Trusted by the world leaders

Features

Expert time goes to judgment

Your clinicians, underwriters and quality engineers spend their limited time judging, not learning a tool, so you actually get their input, and at scale. They score model outputs against criteria you define and explain their calls in free-text fields, while custom shortcuts and built-in OCR take the clicks out of the work.

Learn how experts judge on Kili

Review by design

Expert judgment stays consistent because it is designed into the workflow, not left to individuals. You decide where each level of expertise steps in, from consensus on the same asset to a second review by domain experts, and when criteria change, admins update the ontology and review steps without code.

Evidence of every call

You can show, not just claim, that experts reviewed the data and how well they agreed: the evidence a risk committee, regulator or customer asks for. Every decision records who made it and when, what the expert changed from the model’s output stays visible, and agreement is scored per class and per person.

From “is this label right?” to “is this output right?”

Business experts judge what your model says

Advisor messages, summaries, RAG answers, agent responses: generated content should only reach customers once someone qualified says it is right. Your business experts review samples of model outputs against criteria you define for accuracy, tone and compliance, their agreement is measured, and every verdict is kept, so a model that passes review has evidence behind it.

Explore AI Evaluation
The answer your model learns is your expert's. A clinician marks a model's answer about taking ibuprofen with warfarin as incorrect and writes the corrected answer.

Golden datasets your experts stand behind

The ground truth you train, fine-tune and test on is only as good as the people who validated it. Experts create and check golden datasets directly, including deliberate negative cases such as hallucination traps, with consensus showing where they disagree and review steps settling it, so the set holds up when the model is measured against it.

Explore Post-Training
Your specialist judges the retrieval, not just the answer. A specialist reviews a RAG answer about basement flooding and flags that the retrieved context is not relevant to the question.

Ground truth that needs a specialist to call

Extraction from claims files, defect classes on the line, findings in imagery: labeling where the class is a domain call rather than a click. Across images, video, PDF, text and geospatial, experts flag ambiguities as they work, so first-level reviewers self-correct and instructions get clarified mid-project. The same review steps and scoring apply.

Explore Data Labeling
Every class carries your Quality Analyst's definition. A quality analyst outlines a defect on a part's rim and rates it 3 – Severe Defect, with the class definition shown alongside.

I have been using Kili for 6 months now on a wide range of labeling use cases (both in computer vision and natural language processing). The stability offered by the tool is essential when you have tight deadlines and large volumes of data to annotate. Our team of over 1000 workers is accustomed to the tool, we were able to easily integrate our workforce management tool with Kili with the SSO functionality.
Kili is a powerful and easy-to-use tool for data labeling and annotation. The interface is user-friendly and offers several interesting features. The customer support team is also responsive and helpful.
Software to engage both labelers and business lines in the necessary but tedious task of labeling and annotation, served by a dedicated team to listen to your problems.
Thanks to the fact that our AI infrastructure now includes Kili Technology, we can use the tool for all kinds of projects... LCL teams can accelerate drastically the creation of their training datasets, which means a significant improvement for all the parties involved.
With the choice of Kili, we are much more confident about the future. We decided to eliminate a large part of the technical debt by choosing a solution that will be perfectly mastered across a whole range of data science and AI projects.
