Kriya: Tools for Exploring and Generating Action100M-style Video Annotations

Kriya is a set of tools for exploring and generating Action100M-style hierarchical video action annotations. It includes Kriya Visualizer, an open-source web-based tool for visualizing temporal action trees synced with video playback, and a fully automated annotation API tested on EPIC-KITCHENS-100 egocentric videos with promising results. The project aims to make large-scale, high-quality video annotation accessible for training video world models, VLMs, VLAs, and physical AI systems.
