This is the official repository for Qumen.
Qumen is a desktop app for organizing notes as an interactive knowledge graph — write markdown notes, link them together, and see how they connect in a live, explorable graph.
Markdown notes with [[wiki-style links]] between them
Interactive graph view - visualize how your notes connect to each other, drag nodes, zoom, color them
Tables - a Notion-like structured table editor, separate from regular notes
AI chat panel - connect your own provider (local Ollama or any OpenAI-compatible API), no built-in model, you bring the key
Built-in terminal - a real OS terminal alongside your notes
Light / dark themes

When downloading or running Qumen on Windows, you may see a warning from Windows Defender SmartScreen ("Unknown publisher" / "Windows protected your PC").
This is a false positive. It is not caused by malicious code - it happens because the app isn't yet signed with a paid code-signing certificate (EV certificates cost several hundred dollars a year, which an early-stage independent project doesn't have yet). Every release is scanned with VirusTotal before publishing, with a result of 0 detections out of 60 antivirus engines.
You can safely continue by clicking "More info" → "Run anyway", or verify the release yourself using the checksum provided with each release.
Linux builds are not currently GPG-signed. GPG signing for Linux releases is planned for an upcoming update, which will let you verify the authenticity of each release before installing.
This repository also hosts the open-sourced theme and color layer of Qumen (theme.css, color-palette.ts). If you'd like to contribute a new theme or color palette, see CONTRIBUTING.md. The rest of the application's source code is not part of this repository.
The theme and color files in this repository (theme.css, color-palette.ts) are licensed under MPL-2.0.
