NLP Models That Read Like Your Domain Experts

A model that reads a policy number as a date, or a complaint as praise, fails quietly. In Kili, the underwriters, recruiters and clinicians who know your text confirm or correct its entities and categories, for AI evaluation, post-training and text annotation, while Consensus shows how far they agree.

*No credit card required. Risk-free evaluation.

Features

Domain errors found before they ship

Find where your NLP model misreads your domain before your customers do. The underwriters, recruiters and clinicians who know the vocabulary confirm or correct its entities and categories, imported as predictions tagged with the model's name. Their labels come back through the SDK, ready to compare with the model and retrain it.

See how predictions are imported

Judgment calls you can measure

Sentiment, intent and entity boundaries are judgment calls, and you can see how consistent those calls are. Consensus scores how far labelers agree on each entity class or category, Honeypot tests them against answers you trust, and review steps send a sample to senior specialists. Weak spots show up before they reach training data.

Personal data stays inside your boundary

CVs, claims and patient notes don't have to leave storage you control. Keep files in your own AWS S3, Google Cloud Storage or Azure Blob bucket while you use Kili's cloud, or install Kili on your own Kubernetes, with no internet access needed after installation. Every label version keeps its author, label type and date.

NLP text annotation tools for domain experts

  • Named Entities and Relations

    Mark names, amounts, dates or clauses and link them with relations, on text and PDF assets. On plain text, select at token level and propagate an entity to every occurrence from a right-click.
  • Classification with Conditional Questions

    Set up sentiment, intent or topic as single- or multiple-choice categories, and nest a conditional question under a category, so a complaint can carry its reason and its severity in one pass.
  • Pre-Annotation from Your Model or Any LLM

    Import predictions from your own NER or classification model, or from an LLM you prompt, through the SDK or API. Set each asset's priority through the SDK, for example from the model's confidence, so uncertain texts reach experts first.

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.
