A non-linear chat interface for LLMs. Conversations are displayed as a tree structure, allowing you to branch off at any point and explore multiple conversation paths simultaneously.
- 🌳 Tree-based conversations - Branch anywhere, not linear
- 🔀 Merge branches - Combine conversation paths with configurable context
- 🗂️ Artifacts - Add text or images to the canvas and merge them into conversations
- 🖼️ Multimodal support - Vision models can process images (auto-detected from model capabilities, at least works with Openrouter)
- ✏️ Edit propagation - Edit any node and all descendants automatically regenerate
- 🔌 Any OpenAI-compatible provider - OpenRouter, OpenAI, Ollama, LM Studio, etc.
- 💾 Local storage - Everything persists only in your browser
- 🔗 Stateless sharing - Entire conversation trees are compressed into a sharable URL. (Links can get huge)
- Clone the repo
npm installnpm run dev
Option A: Server-side (.env file)
OPENAI_API_KEY=your-key-here
Option B: Client-side (Settings panel)
- Click the ⚙️ icon in the top-left panel
- Enter your API key and optionally a custom API URL
- Use the 🙈 checkbox to save the API key in browser storage
For local LLMs, set the API URL to your local endpoint (e.g., http://localhost:11434/v1 for Ollama).
