GenOffice

1. What is GenOffice?

GenOffice is a free, open-source office suite meant to replace Microsoft Office on Windows, macOS and Linux. It opens and saves real Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) files, and also edits PDF, Markdown and HTML. Every document has an AI panel next to it: you type a request, the AI edits the document itself and shows you what it changed, with a button to undo.

According to the project, the apps are entirely free, with no trial and no paid tier for the software (Apache-2.0 license). Editing happens on your own computer. The AI features need an internet connection and one of two things: a Genspark sign-in, or your own API key.

A good fit if:

• You need to open and edit Word, Excel and PowerPoint files without buying Microsoft Office.
• You want AI to rewrite a passage, build a spreadsheet with working formulas, or draft a slide deck from one sentence.
• You need to convert PDF to Word, Excel or PowerPoint on your own machine, without uploading the file.

Not a good fit if:

• You only use a phone. GenOffice is a desktop application with no mobile version.
• You need a browser-based editor where several people type at once, like Google Docs. The official documentation does not describe such a feature.
• Your computer runs Windows 7/8 or a macOS version older than 11.

2. What you need first

Computer and operating system (from the official download table):

Operating system	Requirement
Windows (most PCs, Intel/AMD)	Windows 10 or newer
Windows on Arm (Snapdragon X and similar)	Windows 11 on Arm
macOS on Apple Silicon or Intel	macOS 11 or newer
Linux Debian/Ubuntu	x86_64, glibc 2.34+ (Ubuntu 22.04 or newer)
Linux Fedora/RHEL/openSUSE	x86_64, glibc 2.34+ (Fedora 35+, RHEL 9+, Leap 15.6+)
Other Linux (AppImage)	x86_64, glibc 2.34+, FUSE 2

Download size: the 0.11.0 installers are roughly 140 to 150 MB on Windows and roughly 180 MB on macOS (sizes of the release files at the time of writing).

Nothing else to install first. No Python, Node.js or Docker.

Accounts and API keys (only for AI features):

• Genspark sign-in: nothing to configure. The README does not state pricing or limits for this option; check https://genoffice.ai/.
• Your own API key (a secret string for calling an AI model): GenOffice accepts keys for Claude, OpenAI, Gemini, DeepSeek, OpenRouter and many other providers, including model servers running on your own machine. The provider bills you by usage.

If you only edit documents and never use the AI, you need no account at all.

3. Step-by-step installation

Step 1: Open the official download page

Go to https://github.com/genspark-ai/genoffice/releases/latest and scroll to Assets (the list of attached files). The latest release when this guide was written is v0.11.0, published on 28 September 2026.

Step 2: Pick the right file for your computer

Your computer	File to download
Ordinary Windows PC	GenOfficeSetup-v0.11.0-x64.exe
Windows on Arm	GenOfficeSetup-v0.11.0-arm64.exe
Mac with an Apple chip (M1 or later)	GenOffice-0.11.0-arm64.dmg
Mac with an Intel chip	GenOffice-0.11.0.dmg
Ubuntu/Debian	genoffice_0.11.0_amd64.deb
Fedora/RHEL/openSUSE	genoffice-0.11.0.x86_64.rpm
Other Linux	GenOffice-0.11.0.AppImage

The version number in the file names changes with each release.

Note: Not sure which Windows PC you have? Open Settings → System → About and read "System type". If it says "x64-based processor", download the x64 file.

Step 3 (Windows): Run the installer

Double-click the .exe you downloaded and follow the prompts. The Windows installers are code-signed, so you should not normally see an "unknown publisher" warning.

What success looks like: GenOffice appears in the Start menu.

Step 3 (macOS): Drag to Applications

Double-click the .dmg, then drag the GenOffice icon into the Applications folder. The macOS installers are signed as well.

What success looks like: GenOffice shows up in Launchpad and opens normally.

Step 3 (Linux): Install from the terminal

Open a terminal in the folder that holds the downloaded file.

Ubuntu/Debian:

sudo apt install ./genoffice_0.11.0_amd64.deb

Fedora/RHEL:

sudo dnf install ./genoffice-0.11.0.x86_64.rpm

openSUSE:

sudo zypper install ./genoffice-0.11.0.x86_64.rpm

AppImage (runs in place, no install). Install FUSE 2 first; on Ubuntu 24.04 the package is called libfuse2t64, on older releases libfuse2:

sudo apt install libfuse2
chmod +x GenOffice-0.11.0.AppImage
./GenOffice-0.11.0.AppImage

What success looks like: with .deb and .rpm, GenOffice is added to the applications menu; with the AppImage, the app window opens straight away.

4. First use

Step 1: Open the app and read the first notice

On first launch GenOffice shows an onboarding screen that includes a notice about anonymous usage statistics (see section 7 for how to turn them off). Then you reach the home screen, where you create new documents or search your files by name and by content.

Step 2: Open an existing Word file

Open any .docx on your computer. It appears laid out as it would be in Word. Change a few words and save. GenOffice rewrites only the parts you edited and leaves the rest of the file untouched, so the document still opens normally in Microsoft Word.

Step 3: Turn on the AI

Go to Settings → AI and do one of the following:

• Sign in with Genspark, or
• Choose the provider you have (for example Claude, OpenAI, Gemini or DeepSeek) and paste your API key.

Step 4: Ask the AI for something specific

Return to your document, open the AI panel and type a request such as "Make the introduction shorter". The AI edits the document directly. Each AI turn is a snapshot you can roll back with one click. With Track changes on, the edits arrive as Word-style revisions.

More things to try:

• In a spreadsheet: ask for a summary sheet. You get real formulas (for example SUMIF), not pasted numbers.
• In Slides: describe a presentation in one sentence and the AI drafts the slides as an editable .pptx.
• In PDF: use PDF Converter → PDF to Word to turn a PDF into a .docx on your own machine.

5. Common errors and fixes

Symptom	Cause	Fix
The Windows installer will not run or reports incompatibility	You downloaded the arm64 build for an Intel/AMD PC, or the reverse	Check "System type" as in Step 2 and download the correct file
The AppImage will not start and mentions FUSE	FUSE 2 is not installed	Install libfuse2 (libfuse2t64 on Ubuntu 24.04) and try again
The AppImage gives "Permission denied"	The file is not marked as executable	Run chmod +x on it as in Step 3
The AI panel does not answer	No Genspark sign-in, no API key, or no network	Check your connection, then open Settings → AI and sign in or paste a key
Typing genoffice in a terminal gives "command not found"	The command-line tool lives inside the app and is not on your PATH	Open Settings → Integrations, which prints the exact path of the command on your machine
A scanned PDF converted on Linux has no editable text	The docs mention system text recognition (OCR) for scans on macOS and Windows only	Do the conversion on a macOS or Windows machine
An older Linux system refuses to install it	glibc is older than 2.34	Upgrade to one of the releases listed in section 2

6. Uninstalling and updating

Updating

GenOffice has in-app updates. You can also download the newest installer from the Releases page and install it over the old version. On Linux, install the new .deb or .rpm with the same command as in Step 3.

Uninstalling

The README has no uninstall section, so use your operating system's normal method:

• Windows: Settings → Apps → Installed apps, find GenOffice and choose Uninstall.
• macOS: drag GenOffice from Applications to the Trash.
• Linux (AppImage): delete the AppImage file.
• Linux (deb/rpm): remove it with your distribution's package manager. For example on Ubuntu/Debian:

sudo apt remove genoffice

Your documents are ordinary files on disk and are not deleted when you remove the app.

7. Frequently asked questions

Does it cost money?

The apps are free, with no trial and no paid tier for the software. Costs can only arise on the AI side, if you use a paid API key from a model provider.

Does it work offline?

Editing, saving and converting run entirely on your computer and need no network. The AI features (assistants, web search, image tools) need a connection.

Are my documents sent anywhere?

Opening, editing, saving and converting all happen locally. Content leaves the machine only when you use the AI, and then it goes to the provider you chose. Separately, official builds send anonymous usage statistics by default (for example an app-launch event, or the extension of a file you open). According to the privacy document these never include document content, file names, file paths or email addresses. Turn them off under Settings → General → Send anonymous usage statistics.

Will files made in GenOffice open in Microsoft Office?

Yes. GenOffice saves native .docx, .xlsx and .pptx, and keeps every part you did not edit byte-for-byte.

Can GenOffice edit PDFs?

Yes. It edits text and images inside the page using the original fonts, and converts PDF to Word, Excel and PowerPoint on your device.
