Bloom is a local-first screen recorder built for agentic workflows.
- Record locally — No lock-in, your files stay yours
- Upload to VideoDB — Automatic cloud sync with AI processing.
- Find any moment — Transcripts, visual embeddings, metadata.
- Let agents work on your recordings — Query via APIs or agent frameworks like Claude Code and access your recordings data.
Recordings are no longer files, they are inputs for AI.

Recording flow: The app creates a CaptureClient which spawns a native binary to capture screen, mic, and system audio. Chunks are uploaded to VideoDB Cloud in real-time. A WebSocket connection delivers session events (started, stopped, exported) back to the app.
Post-recording: Once the video is exported, the app calls the VideoDB API to index spoken words, generate a transcript, and create a subtitled stream — all available for in-app HLS playback or sharing via URL.
The UI layer is fully open source.
- Modify it — Customize the interface to your needs
- Extend it — Add new features and workflows
- Plug it in — Integrate with your own systems
Bloom is not just a tool. It's a foundation for building agentic systems on top of recordings.
Your recorder should not trap your data.
It should:
- Give you ownership — Local-first, no lock-in
- Enable intelligence — AI-ready from day one
- Power your agents — APIs and integrations built-in
Bloom is built for that future.
- Node.js 18+
- VideoDB API Key (console.videodb.io)
npm install
npm startOn first launch, grant microphone and screen recording permissions, then enter your VideoDB API key.
