What it does Rocketnotes is a web-based Markdown editor with a document tree, semantic search, and the usual AI trimmings—chat with your notes, copilot-style completions, voice-to-text. You can run it in the cloud or self-host entirely via Docker with Ollama for local LLMs. There’s also an Electron app and a Neovim plugin if you prefer staying in the terminal.

The interesting bit The standout is the “agentic archiving” workflow: you dump snippets into a Zettelkasten-style inbox, and a LangGraph-powered agent figures out which existing document each snippet belongs in, then files it there automatically. It’s the rare note-taking app that tries to solve the “where did I put that?” problem before you even ask.

Key highlights

• Hierarchical document tree with drag-and-drop and pinned favorites
• Semantic search via sentence-transformers (cloud: S3 Vectors, local: ChromaDB)
• Multi-LLM support: OpenAI, Anthropic, Together AI, or local Ollama
• MCP server integration—expose your knowledge base to other LLM tools
• Neovim plugin for editor-native note-taking
• Backend is Go and Python; frontend is Angular/TypeScript

Caveats

• The macOS Electron app isn’t signed with an Apple developer license, so Gatekeeper will flag it
• AWS stack (DynamoDB, S3, Cognito) is baked into the cloud deployment; local Docker is the escape hatch

Verdict Worth a look if you’re a developer who likes Zettelkasten methods but hates manual filing, or if you want an Obsidian alternative with heavier AI integration and a proper self-hosted option. Skip it if you need mobile apps or collaborative real-time editing—neither is mentioned.
