Read the Terms of Service

GenOffice is a free, open-source alternative to Microsoft Office for macOS, Windows and Linux. It opens and saves native .docx, .xlsx and .pptx files, edits PDF, Markdown and HTML, and puts an AI agent next to every document — not a chat box bolted on the side, but an editor that reads the file, makes the change, and shows you exactly what it touched.

Real formats, byte-preserving. Only what you edit is rewritten. Everything else in the file survives byte-for-byte, so documents keep working in Word, Excel and PowerPoint.
AI you can review. Edits land as tracked changes and diffs with one-click rollback. Spreadsheets get live formulas, not pasted numbers. Decks and pages are generated onto the canvas and stay fully editable.
Local by design. Files open, edit, save and convert on your machine. PDF → Word / Excel / PowerPoint, Markdown → Word and HTML → Word all run on-device. Only the AI calls leave the machine, to the provider you choose.
Your keys or none. Sign in with Genspark and skip keys, or bring your own key for Claude, OpenAI, Gemini, DeepSeek, Kimi, GLM, Qwen, Doubao, MiniMax, Grok, Mistral, OpenRouter, or any OpenAI-compatible endpoint, local servers included.

Demo

Six apps, one AI panel. Every screenshot is the real app on macOS, with the AI driven from the prompt you can read in the panel.

1 · Docs — open and edit `.docx` with an AI you can review

2 · Sheets — `.xlsx` with live formulas and charts, not pasted numbers

3 · Slides — from a prompt to a `.pptx` deck

4 · PDF — edit PDF text in place, convert PDF to Word on-device

5 · HTML — an AI page and UI builder, design brief first

Say what the page is for and who it is for. The AI proposes a design brief first — hook, palette, typography and style directions — then builds a single self-contained .html file against those tokens.
