Kino is a video-production workspace that combines media storage, editing, and team review with AI coding agents. Its central idea is to treat editing as code: timelines, motion graphics, 3D scenes, and comments are represented in a Remotion-based system that agents such as Codex and Claude Code can manipulate. Projects, clips, individual frames, and feedback each have links, giving people and agents a shared, addressable source of truth instead of relying on vague instructions or scattered screenshots. Teammates can collaborate in real time, see one another’s cursors, and leave notes that agents can apply.

To make this practical with large, professional footage, Kino analyzes media through transcription, embeddings, descriptions, and face detection, while local playback and low-resolution cloud proxies support collaboration and inference. Custom decoders handle formats including ProRes, BRAW, and R3D, and the developers say WebCodecs and related libraries enabled the performance. The company began with custom deployments for film and television productions, but rebuilt Kino in 2025 after finding that studio workflows limited access to newer AI models and broad improvements to editing. Users now include businesses producing ads with agent assistance and filmmakers running many agents on shared projects. The Electron app’s editor, imports, exports, collaboration, and basic agent access are free; a $25-per-editor monthly Pro plan adds storage, YouTube search, share links, and expanded agent tools.
