Seline is an AI assistant that blends chat, visual tools, and a local knowledge base into a single desktop app. It runs mostly on your machine—your documents stay private, your conversations persist across sessions, and you can switch between LLM providers without leaving the app.
- Chat with configurable agents and keep long-running sessions organized.
- Enhance prompts with grounded context from your synced folders and memories.
- Generate and edit images, then assemble them into videos.
- Run vector search locally with LanceDB for fast, private retrieval.
- Windows (installer builds are available).
- macOS is supported today; DMG distribution is coming soon. You can build macOS packages from source in the meantime.
- Linux, not tested.
For end users: none beyond the OS installer.
For developers:
- Node.js 20+ (22 recommended for Electron 39 native module rebuilds)
- npm 9+
- Windows 10/11 or macOS 12+
npm installnpm run electron:devThis runs the Next.js dev server and launches Electron against http://localhost:3000.
# Windows installer + portable
npm run electron:dist:win
# macOS (DMG/dir)
npm run electron:dist:macFor local packaging without creating installers, use npm run electron:pack. See docs/BUILD.md for the full pipeline.
