Gedonus is a PowerPoint add-in that gives you version control, shape-level diffs, and a full change history for every deck you work on — without changing how you use PowerPoint.Think of it as Cursor for PowerPoint: AI edits your slides, Gedonus shows you exactly what changed and whether every number is correct.
Clone the repository from GitHub, run npm install and npm start, then sideload the add-in into PowerPoint using the manifest.xml file. It takes about five minutes.See the Installation guide for step-by-step instructions. No account required, nothing to configure — it runs entirely on your machine.
No. Gedonus stores everything locally using your browser’s Origin Private File System (OPFS). Your slides, your version history, your diffs — none of it is sent anywhere.If you choose to connect a GitHub repository, that sync goes directly between your machine and your own repo. Gedonus never has access to your data.
Gedonus is source-agnostic: it tracks what changed in your deck regardless of how the change was made. Human edit, Claude for PowerPoint, Microsoft Copilot, a python-pptx script — Gedonus sees all of it.For AI generation inside PowerPoint, we currently recommend using Claude for PowerPoint alongside Gedonus: Claude to generate and edit, Gedonus to track, diff, and review.
Yes, fully. Gedonus is open source under the MIT licence. Free to use, free to modify, free to self-host. The code is public on GitHub and always will be.
Yes. You can link any GitHub repository and Gedonus will sync your version history there — committed under your account, in your repo, with your data. No Gedonus account, no third-party storage, no lock-in. You own everything.
Not currently. The add-in requires PowerPoint desktop (Windows or Mac). Web support is on the roadmap.
The top priorities are:
  • Per-shape accept/reject — review and selectively accept AI edits, shape by shape
  • Brand compliance checks — automatic detection of off-brand fonts, colors, and layouts
  • Approval workflows — structured sign-off before decks go out
  • Source verification — flag numbers that cannot be traced to a linked data source
  • Native AI generation — prompt-to-diff directly inside the Gedonus task pane
See the individual feature pages for details on each.
