Your clipboard, but it writes a Wikipedia about you

What it does

OpenWiki is a Tauri-built desktop app that sits in your system tray and pops up whenever you copy text, an image, or a URL. You choose what to keep, and the app stashes it in a local SQLite database. From there, LLMs compile the fragments into wiki pages, draw knowledge graphs, and generate weekly “attention analysis” reports that try to map your information habits. It is essentially a clipboard manager that aspired to become a second brain.

The interesting bit

The clever part is the opt-in capture: the popup auto-dismisses after ten seconds, so nothing is silently hoarded. Once saved, the content is not just stored but synthesized—AI extracts concepts and entities, surfaces orphaned pages, and lets you query your own pile of notes via a sidebar. It is Andrej Karpathy’s “LLM Wiki” idea packaged as a desktop utility, with MCP protocol support so it can talk to Claude Desktop.

Key highlights

• Clipboard-triggered capture with manual keep/discard and source-app detection.
• Local-only storage in SQLite; LLM calls go out, but the corpus stays on disk.
• Auto-compilation of snippets into wiki pages, plus a knowledge graph and an “Ask sidebar” for RAG-style questioning.
• Weekly AI-generated insight reports with seven attention-analysis dimensions (including charming labels like “Graveyard” and “Blind Spots”).
• Supports Claude, OpenAI, and Gemini via API key or OAuth; unsigned builds for macOS and Windows.

Caveats

• macOS and Windows builds are unsigned, so expect security warnings on first launch.
• YouTube subtitle extraction requires separate installation of yt-dlp and Node.js.

Verdict

Worth a look if you are a note-taking maximalist who wants AI to impose structure on your daily copy-paste stream. Skip it if you already have a clipboard manager you love and do not need LLMs to tell you what you were thinking last Tuesday.
