Generate slides with Claude, Copilot or any AI model. See exactly what changed. Accept or reject every edit — shape by shape. The complete AI-native presentation workflow, inside PowerPoint.
The problem
You know PowerPoint. Every shortcut, every layout, every way to make a waterfall chart land exactly right. That expertise took years — and it's not going anywhere. When Claude for PowerPoint shipped, it worked because it met you inside the tool you already master.
The teams that will win are the ones who adopt AI inside PowerPoint and stay in control of it. Faster iteration, cleaner versions, every number traceable to its source. Not slower because of review overhead — faster because the review is already built in.
Scenario
Your analyst uses Claude to rebuild the financials section. Four slides, four minutes. Instead of scrolling through every shape manually, Gedonus surfaces exactly what changed — she accepts the right edits and flags the ones that need another look, shape by shape, in seconds. The VP sees what shifted since the last update without opening a single old file. The MD runs a brand and numbers check in one click before the IC pack goes out. The same deck that used to take a full review cycle closes the loop in one session — and the deal moves faster because of it.
How it works
AI Assistants
Extract & generate
Tool-agnostic in PowerPoint — Gedonus applies the same features no matter which AI assistants feed your deck.
GEDONUS
Sync & storage
Your data. Your infrastructure.
Versions sync straight to your repos and libraries — peer-to-peer only; Gedonus never stores your data. Link a reference deck for automatic house-style checks.
Data sources
Numbers you can trust.
Bloomberg
Refinitiv
Tie deck figures to live feeds. Gedonus flags drift from source and refreshes values proactively.

Industries
Pitch books, CIMs and client decks go through dozens of iterations before they leave the firm. Claude rewrites your financials section in four minutes. Gedonus shows you exactly which numbers shifted, who touched what, and locks the right version before it hits the MD's inbox.
Your investment thesis moves faster than any slide deck can keep up with. When AI rewrites the narrative overnight, Gedonus gives you a shape-by-shape diff so you accept what works, reject what doesn't, and the allocator sees only what you intended.
IC packs, portfolio reviews and LP updates are rebuilt every cycle. AI accelerates the first draft. Gedonus makes every revision traceable from first prompt to final vote, so materials are always IC-ready without the version chaos.
Client communications need to be precise, on-brand and fast. Gedonus preserves your house style automatically while you iterate with AI — every change tracked, every version signed, so what goes to clients is always exactly what you approved.
Capabilities
Save any state of your deck with a message, timestamp and author. Every version is stored locally — restore, compare or branch at any point without leaving PowerPoint.
See exactly what changed between any two versions, down to individual numbers and text boxes. Accept or reject every AI edit shape by shape, just like reviewing code in Cursor.
Generate slides with Claude, GPT or Gemini directly inside PowerPoint. Automatic content and brand compliance checks flag wrong or suspicious numbers and off-spec fonts, colors etc.
FAQ
Gedonus is a PowerPoint add-in that sits inside your existing workflow. It 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 and everything looks great.
Clone the repository from GitHub, run npm install and npm start, then sideload the add-in into PowerPoint. It takes about five minutes. Full instructions are in the README. No account required, no cloud setup, nothing to configure. It runs entirely on your machine. Later this year Gedonus will also be available directly through the Microsoft AppSource add-in store.
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 license. 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.
Shape-level accept and reject for AI edits, brand compliance checks, approval workflows before send, source verification, and AI-driven content extraction and slide generation. Everything with your employees in control.
Gedonus is MIT-licensed and open source so teams can adopt and extend the governance layer for AI-driven presentations with full transparency.
