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.
- 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. - Ask your files, with sources. Star a set of documents and Ask AI on the home screen answers questions across them, citing the file behind every claim so you can open it and check.
- 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, Cheaper Inference, Atlas Cloud, 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.
Get it: macOS (Apple Silicon and Intel) · Windows (x64 and Arm) · Linux (deb, rpm, AppImage) — details and requirements in Download.
Six apps, one AI panel, a file search reranked by TypeSafe Jev, an Ask AI that answers from your starred files with sources, 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.
 |  |
| Opens the file as Word lays it out — 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. | Ask for the edit — 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 Track changes on, edits arrive as Word-style revisions. |
 |  |
Build it — from one sentence the agent adds a Summary sheet with real SUMIFs by region and category, inserts a column chart, and applies the 43 changes as a single undoable batch. | Ask it — questions about the workbook come back with the reasoning and the exact cells used as clickable citations. Under the hood: an in-house Rust .xlsx engine, pivot tables, slicers, conditional formatting and formula tracing. |
 |  |
One line in — "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 .pptx. | A finished deck out — 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. |
 |  |
| Edit inside the page — 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. | Convert on-device — PDF Converter → PDF to Word produces an editable .docx 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. |
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.
 |  |
| Generated from one prompt — a bold hero, feature cards, pricing and a waitlist form for Lumen, built in the Midnight Studio direction. Click any element to restyle it, double-click to edit text, or switch to the CodeMirror source view. | Same design, new direction — one Restyle request swaps the brief's tokens and the page follows: warm paper, editorial serif, sun-orange accent, nothing rewritten. Present fullscreen, or export as PDF or a native editable Word document. |
 |  |
| UI mockups — the "personal dashboard" starter turns a persona into a working layout: left rail, greeting, billable-hours sparkline, invoice and utilization cards, all real HTML you can hand to a developer. | Data stories — the "data report" starter builds an editorial broadsheet: serif masthead, one headline number, a rule-separated stat row, inline SVG charts and a methodology note. |
 |  |
| Ask AI about a selection — select any passage and an Ask AI chip appears: type an instruction or pick a suggestion, send it now, or queue several anchored edits and run them in one pass. The same entry exists in every app. | Rendered, saved as plain Markdown — headings, lists, tables, images, code blocks and Mermaid diagrams in a Tiptap block editor, written back as plain .md, with a fully local Markdown → Word export. |
Every file in your work folder is indexed on-device: names, folders and the extracted text of Word, Excel, PowerPoint, PDF, Markdown and HTML files, in a SQLite full-text index with CJK-aware tokenizing. Switch on Jev search reranking and the top 20 local hits are judged by TypeSafe Jev, the System One model that returns one calibrated relevance score per document in a single call instead of generating text. The list is reordered by that score; if the call fails or times out, the local order stays.
 |  |
| Same words, different answers — "laptop refresh policy" matches a browser-cache refresh policy, a brand-refresh plan and a dashboard-refresh schedule word for word, so full-text ranking puts them first. Jev reads the excerpts and moves the equipment standards document, the one that states the three-year replacement cycle, to the top. The Jev badge next to the result count shows when the order came from the model. | Off by default, one switch to turn on — Settings → AI Media & Search → Local file search. Pick OpenRouter or TypeSafe direct, paste a key, hit Test connection. Only when the switch is on do excerpts of the top hits leave the device; the index itself never does. |
Star the files you work with and the home screen's Ask AI treats them as a knowledge base. Ask a question in plain language; the agent searches the starred files, reads the ones it needs and answers with a citation after every claim. Click a citation and the file opens in the right app.
Ask AI searches the same on-device full-text index as Search and reads files in pages, so the model only sees the hits and the passages it asked for, through the provider you chose.
GenOffice ships a genoffice command line and an agent skill. Install the skill and Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode or Windsurf can create, convert, read and edit real Office files through the same engines as the apps, without opening a window.

One prompt to your agent — "Build an eight-slide deck about the Solar System." The agent reads the skill, writes a style sheet, an outline and one page spec per slide, generates the two photos with genoffice image, and lets genoffice slides check reject anything that overflows or overlaps before genoffice create assembles the .pptx and slides render hands back a PNG per slide to look at. |
