Our assessment of genoffice
genoffice scores 88/100 on our quality scale, 342nd of 600 Data & Analytics skills we index.
Its CLAUDE.md is 44 KB long, well organised into 31 sections with 11 code examples: long enough that it reads more like full documentation than a focused instruction file, which agents can find harder to follow.
With 11,276 GitHub stars, it is one of the more widely adopted skills in the catalogue.
Maintenance, license and trust
- The repository was last updated today, so genoffice is actively maintained.
- Our last check on 2026-10-17 found the source still online.
- It is released under the Apache-2.0 license, a permissive license that allows use, modification and commercial use with attribution.
- Its trust signals score 100/100, with no cautions. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

- Run
npx skills add genspark-ai/genoffice. The install tabs above show the steps for each supported agent. - Which AI agents does genoffice work with?
- It is written for Claude Code, Cursor and OpenAI Codex, as a CLAUDE.md file. Other agents that read the same format can often use it too.
- Is genoffice safe to use?
- Our scan of the whole file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful. It is Apache-2.0-licensed and scores 100/100 on trust signals. Skills are instructions an agent will follow, so read the file before installing it and do not approve commands you do not understand.

Skill content
View source on GitHubGenOffice 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.
- Find files by what they say. The home screen searches the names,
folders and full text of your
.docx,.xlsx,.pptx, PDF, Markdown and HTML files from a local SQLite index, CJK included. Optionally, the top hits are reranked by TypeSafe Jev, the System One judgment model, so the file that answers your question comes first. - 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, Requesty, Opper, or any OpenAI-compatible endpoint, local servers included.
- Scriptable and agent-ready. The app ships a
genofficecommand line and a skill for Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf, so a coding agent can create, convert, read and edit real Office files on your machine without opening a window.

Demo
Six apps, one AI panel, a file search reranked by TypeSafe Jev, and a command line for your coding agent. 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
<table>
<tr>
<td width="50%"><img src="docs/assets/readme/docs-report.webp" alt="GenOffice Docs rendering a two-column annual-report page with a full-width cover image, shaded KPI table, header and footer, at 80% zoom with the AI panel collapsed"></td>
<td width="50%"><img src="docs/assets/readme/docs-ai.webp" alt="GenOffice Docs: a company overview with a banner image; the AI tightened the Overview and inserted a new bulleted section, and the panel offers a one-click roll back"></td>
</tr>
<tr>
<td><b>Opens the file as Word lays it out</b> — two-column sections, full-bleed images, shaded tables, headers and footers, pagination on Word's line metrics. Styles, comments, tracked changes, equations and ink round-trip untouched.</td>
<td><b>Ask for the edit</b> — the AI reads the blocks it needs, rewrites the Overview and inserts a new bulleted section. Every AI turn is a snapshot you can roll back; with <b>Track changes</b> on, edits arrive as Word-style revisions.</td>
</tr>
</table>
2 · Sheets — .xlsx with live formulas and charts, not pasted numbers
<table>
<tr>
<td width="50%"><img src="docs/assets/readme/sheets-ai.webp" alt="GenOffice Sheets: the AI added a Summary sheet with revenue by region and category using SUMIF formulas, plus a column chart, and reports 43 applied changes with an Undo button"></td>
<td width="50%"><img src="docs/assets/readme/sheets-qa.webp" alt="GenOffice Sheets: asked which region led Q2 revenue, the AI answers Europe with the category breakdown and cites the cells it used as links, next to the Orders sheet"></td>
</tr>
<tr>
<td><b>Build it</b> — from one sentence the agent adds a Summary sheet with real <code>SUMIF</code>s by region and category, inserts a column chart, and applies the 43 changes as a single undoable batch.</td>
<td><b>Ask it</b> — questions about the workbook come back with the reasoning and the exact cells used as clickable citations. Under the hood: an in-house Rust <code>.xlsx</code> engine, pivot tables, slicers, conditional formatting and formula tracing.</td>
</tr>
</table>
3 · Slides — from a prompt to a .pptx deck
<img src="docs/assets/readme/slides-generate.webp" alt="Time-lapse of GenOffice Slides generating the Aurora Home investor deck: the AI plans the storyline in the panel, slides appear on the canvas one after another, and the finished deck ends on the closing ask" width="100%">
<table>
<tr>
<td width="50%"><img src="docs/assets/readme/slides-cover.webp" alt="GenOffice Slides: the cover slide of an AI-generated Aurora Home investor deck on the canvas, with the original one-line prompt and the AI's summary of what it built in the panel"></td>
<td width="50%"><img src="docs/assets/readme/slides-ai.webp" alt="GenOffice Slides: the designed closing slide of the same 11-slide deck, with the thumbnail strip on the left and the AI panel summarizing the storyline"></td>
</tr>
<tr>
<td><b>One line in</b> — "Create a 10-slide investor pitch deck for Aurora Home…". GenOffice plans the storyline, researches the numbers, and drafts every slide onto the canvas as a real <code>.pptx</code>.</td>
<td><b>A finished deck out</b> — eleven designed slides with consistent typography, imagery and a closing call to action; keep editing with masters, layouts, smart guides and non-destructive cropping, or ask the panel to restyle, rewrite and reorder.</td>
</tr>
</table>
4 · PDF — edit PDF text in place, convert PDF to Word on-device
<table> <tr> <td width="50%"><img src="docs/assets/readme/pdf-edit.webp" alt="GenOffice PDF: Edit text mode outlines every text block on the page for in-place editing while the AI panel answers a question about the report with page citations"></td> <td width="50%"><img src="docs/assets/readme/pdf-convert.webp" alt="GenOffice Docs showing a Word document converted locally from the Helios quarterly review PDF, opened in a second tab beside the original PDF"></td> </tr> <tr> <td><b>Edit inside the page</b> — Edit text mode outlines every text block for in-place retyping; the content stream is rewritten through PDFium with the original fonts, not a cover-up annotation. Ask the AI about a long report and get answers with page citations.</td> <td><b>Convert on-device</b> — <b>PDF Converter → PDF to Word</b> produces an editable <code>.docx</code> that opens in Docs next to the source, headings, stat rows and paragraphs intact. Excel and PowerPoint targets work the same way; scanned pages go through the system OCR.</td> </tr> </table>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.
