The Second Brain Gnome Users Deserve. Go Ahead, HN. Flag This OpenSourceProject

Gknowledge 0.3, the GNOME app that turns documents into an LLM-maintained wiki, was released six days after version 0.2 with a Flatpak build that installs on any Linux distribution via the GNOME 51 runtime, opening files through portals rather than the home folder and including PDF import. The release adds stale-source detection that compares each ingested source against its original file and re-extracts changed versions on Update, re-ingest and remove options that keep pages still supported by other sources, and a new stale_sources MCP tool available on PyPI via uvx gknowledge-mcp so Claude Code, Codex or Cursor can check the wiki for drift.

Open Source AI

gknowledge 0.3 is out. Six days after 0.2, the native GNOME app that turns your documents into an LLM-maintained wiki now installs on any Linux distribution, and it knows when a page is out of date.

What's new in 0.3.0 #

  • Flatpak for every distro. Fedora, Arch, openSUSE, Ubuntu: one command, GNOME 51 runtime, no access to your home folder (files are opened through portals), PDF import included.
  • Pages that know their source changed. Wiki pages rarely go wrong because the model hallucinates; they go stale because the document they came from changed. gknowledge now compares every ingested source with its original file, marks the ones that changed, andUpdate re-extracts the new version. Thanks to Justin (@fromthearchitect ) for the feedback that started this.
  • Re-ingest and remove sources , keeping shared pages that other sources still support (thanks@Aaqibhafeezkhan ,Show us the smallest useful thing you built on an API #30 ).
  • MCP : a newstale_sources tool, so Claude Code, Codex or Cursor can check the wiki for drift. The server is on PyPI:uvx gknowledge-mcp .

Install #

On any distribution with Flatpak:

flatpak install --user https://openapi.github.io/gknowledge/io.github.openapi.Gknowledge.flatpakref
