Have experts classify your videos on Ango Hub. Frame by frame, or video by video.

A visual editing timeline that's built to be intuitive and quick to use, with shortcuts for every action and easy keyframe manipulation.

Ango Hub supports all codecs natively supported by the web browser, in the mp4, mov, webm, and mkv formats.

Ango Hub streams video assets in, rather than attempting to load them all at once. Your experts start working right away.

Powered by our Workflow Designer. Set up your project exactly how you need, with as many layers and integrations as you want.
Your experts don’t have to start from scratch every time. Import pre-annotations so they have a head-start.

Radio buttons, checkboxes, free plain and rich text, single- and multi-dropdowns, trees, and more.
Build and adjust your entire video project workflow without code, even while it’s running.
Deploy in your own environment for full control of data and workflows.
Comment on any frame or label and keep threads open until resolved.
Add formats, integrations, or ML models with a Python-based Ango plugin.
Human-guided suggestions accelerate work while keeping oversight.
Run custom validation the moment work is submitted to enforce rules.
Create projects, add assets, query stats, and export annotations, all from code. Clean REST endpoints and a Python SDK that stays out of your way. All HIPAA, SOC II, and GDPR compliant.

Deploy Ango Hub on your own infrastructure, and run it completely air-gapped. Or run it on your own AWS, GCP, or Azure remote servers.
Receive events the moment they happen, such as asset created, label updated, or review passed. Then wire them into your training loop for rapid, active learning.
On all deployment versions of Ango Hub, your data is always encrypted, in rest and in transit, using the latest industry standards.
