QOwnNotes

QOwnNotes is a desktop notepad and todo manager for people who want to keep their notes in ordinary Markdown files on their own computer. It can use existing text files directly, so your notes remain accessible outside the app.

• Editing and search: Write with Markdown highlighting, image previews and heading folding, then search across notes with matching text highlighted.
• Linked notes: Connect notes with wiki-style links, backlinks and links to individual headings, and organize files across multiple note folders.
• Sync and recovery: Sync through Nextcloud, ownCloud, Syncthing or Dropbox; server-based note history and trash recovery require the QOwnNotes Nextcloud app or a supported legacy QOwnNotesAPI server.
• AI and agent access: Choose OpenAI or Groq for hosted AI, or install an Ollama or llama.cpp backend script to use models running on your computer. AI tools can complete, summarize, translate or edit selected text. The built-in MCP server lets external AI agents search and fetch notes.
• Customization and capture: Adapt the app with scripts and keyboard shortcuts, and capture selected browser text through the Firefox or Chrome Web Companion extension.

QOwnNotes is free and open source under GPL-2.0, with native apps for Linux, macOS and Windows designed for low CPU and memory use. Notes stay as local files unless you sync them or share them with an external service. Accessing todo lists through the web or mobile devices requires the Nextcloud or ownCloud Tasks backend.
