Brainstorm Notebook

Brainstorm Notebook turns your AI conversations into interactive mind-map graphs. Each conversation turn becomes a node, with edges showing how topics flow and connect across the discussion.

SUPPORTED PLATFORMS
- Claude (claude.ai)
- ChatGPT (chatgpt.com)
- Google Gemini (gemini.google.com)

FEATURES
- Auto-generated mind-maps — conversation turns are analyzed and turned into a graph of connected topics
- Real-time updates — new nodes appear automatically as you chat
- Batch rebuild — analyze an entire conversation at once
- LLM / non-LLM mode — toggle between AI-powered analysis and instant keyword-based graph building
- Multi-provider API support — works with Anthropic, OpenAI, and Google Gemini API keys
- Interactive canvas — pan, zoom, drag nodes, click to highlight ancestor chains
- Manual edge editing — connect or cut edges to refine the graph
- Scrollable node details — hover over any node to inspect its full title and summary
- Encrypted key storage — API keys encrypted at rest with AES-256-GCM
- Cache management — view cache size and clear graphs by age
- Per-conversation persistence — graphs saved locally

HOW IT WORKS
1. Open a conversation on any supported platform
2. Click the floating button to open the panel
3. Click Rebuild or let it auto-detect new responses
4. Explore the graph — click nodes to trace topic ancestry
