The world's first full-featured open-source AI Office suite.
HermesOffice is a free, open-source alternative to Microsoft Office for macOS,
Windows, and Linux, built around AI editing as a first-class workflow rather
than a bolted-on chat box. It opens and saves the real Microsoft Office
formats — Word (.docx), Excel (.xlsx), PowerPoint (.pptx) — and edits
PDF and Markdown too: a word processor, spreadsheet, presentation editor,
PDF editor, and Markdown editor as six Electron apps sharing one engine
layer.

Features
- Real PDF editing — retype text and edit images in the page itself, original fonts preserved.
- Local PDF → Word / PowerPoint / Excel conversion — turn a PDF into an editable
.docx,.pptx, or.xlsxentirely on your machine: no cloud, no upload. - Scanned PDFs too — on macOS and Windows scanned pages are read with the system OCR, so they convert to editable text.
- Microsoft Word–compatible, byte-preserving
.docxediting — only what you touched changes; Word never notices. - Word-faithful pagination — page breaks land where Word puts them.
- Excel-compatible spreadsheets — in-house engine with a Rust
.xlsxsidecar, own charts, pivot tables, slicers. - PowerPoint-compatible presentations — in-house
.pptxengine with masters, layouts, smart guides, non-destructive crop. - Markdown to Word, fully local — the same OOXML engine, no Pandoc, no cloud.
- AI that edits documents — block-level edits with snapshots and diffs, document-aware agents.
- Bring your own key (BYOK) — run the AI on your own API key: Claude, OpenAI, Gemini, DeepSeek, Kimi, GLM, Qwen, Doubao, MiniMax, Grok, Mistral, OpenRouter, or any OpenAI-compatible endpoint — or sign in with Genspark and skip keys entirely.
- Agent tools built in — web/image search, image generation, media analysis.
- Light / dark / system themes.
- macOS, Windows, Linux.
- Free & open-source (Apache-2.0).
