Experts Judge the Frames That Matter, with Video Annotation Built Around Them

Your domain experts make the calls only they can make, at the frames where something changes. Kili tracks and interpolates between them, routes footage through the review steps you design, and keeps a record of who labeled what, so you can trust the training and evaluation data you ship.

*No credit card required. Risk-free evaluation.

Features

Experts have the final say

The people who know what a defect or a threat looks like get the final say. Add a review step for each level of expertise and set how much each step sees. Reviewers edit annotations, raise issues on boxes and polygons, answer labelers' questions, and send videos back for rework.

Key frames from experts, tracking for the rest

Experts set key frames and confirm tracks instead of drawing every frame. Kili interpolates boxes and points between key frames, smart tracking carries a bounding box forward until the next key frame, and Meta's SAM tracking follows a segmented target across the next 50 frames. Experts correct only where it drifted.

Your footage stays where it is

Sensitive footage doesn't have to move to be labeled. Connect your own AWS S3, Azure Blob Storage or Google Cloud Storage bucket so video stays in your storage, or install Kili on your own Kubernetes cluster with no internet access needed after installation. Every label keeps its author, label type and date, and access is set by role and project.

Video annotation tools, in one project

  • One timeline for every object

    See every annotation on a zoomable timeline, with key frames marked. Annotations propagate over the next 100 frames by default; change the number or turn it off. Shortcuts jump ten frames at a time, or straight to the first or last frame.
  • Boxes, points and polygons

    Object detection jobs on video use bounding boxes, points and polygons, and Meta's SAM segments a target from a box you draw, so one project covers the object types your ontology needs.
  • Clean tracks on long footage

    Split an object to start a new one without losing the work already done, or group detections into a single object so the timeline shows one track instead of several.

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.
