bushchat

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.

Features

• 🌳 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)

Setup

1. Clone the repo
2. npm install
3. npm run dev

Configuration

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).
