The suite, built by a single developer with $10,000 worth of AI tokens, offers free file editing but routes AI requests through Genspark's service, which passes text to third-party providers including OpenAI, Anthropic, Google, xAI, and ElevenLabs, and lacks its own privacy policy. GenOffice currently supports only Windows x64 and macOS on Apple Silicon, with no Linux build available yet.", "body_md": "Office suites have changed a lot since the first ones landed on desktops decades ago. What began as basic tools for typing letters and totaling numbers has turned into sprawling software loaded with templates, cloud sync, and now, AI.\n\nIt's 2026, and that last part has split the office suite market into two camps.\n\nMicrosoft has leaned into pushing AI everywhere, with Copilot showing up across Word, Excel, and PowerPoint whether you want it there or not. Others have gone the calmer route, building AI in [as something you can turn on](https://itsfoss.com/news/collabora-office-26-04/), not something forced.\n\nGenOffice is a new offering from [MainFunc.ai](https://mainfunc.ai/?ref=itsfoss.com) that strongly focuses on AI, putting it in the first camp, featuring a range of editors that one might expect from a modern office suite.\n\n## GenOffice: A quick look\n\nBuilt by a single developer equipped with **$10,000 worth of tokens** (*for AI*), GenOffice bundles four editors, *Docs*, *Sheets*, *Slides*, and *PDF*, into one **Electron-based desktop app**.\n\nFor `.docx`\n\nwork, **Docs** lets you draft a section, restyle a paragraph, or rewrite it for a different reader from a simple prompt, with the AI working directly inside the document rather than a side panel.\n\n**Sheets**, for `.xlsx`\n\nfiles, runs on [Univer](https://github.com/dream-num/univer?ref=itsfoss.com), an open source spreadsheet engine, paired with an in-house Rust sidecar for reading and writing files.\n\nPresentations run through **Slides**, which builds `.pptx`\n\ndecks from a single prompt, picking a layout, writing the copy, and dropping in data cards as needed.\n\nRounding out the office suite is **PDF**, built on the open source [pdf.js](https://mozilla.github.io/pdf.js/?ref=itsfoss.com) and [pdf-lib](https://pdf-lib.js.org/?ref=itsfoss.com) libraries, letting you read long documents and ask questions about specific passages without you needing to switch between apps.\n\nIt's quite obvious that AI runs through every one of these editors. All of that is made possible via Genspark's [Super Agent](https://www.genspark.ai/helpcenter/super-agent?ref=itsfoss.com), which is treated as a core part of the app rather than a chat window tacked on the side.\n\nOpening, editing, and saving files costs nothing, **but AI features draw from Genspark's credit system**, tying them to an account rather than a local model.\n\nThat matters, because GenOffice doesn't appear to have its own privacy policy. AI features run through Genspark's service, so anything you send them falls under Genspark's [terms](https://www.genspark.ai/terms?ref=itsfoss.com) and [privacy policy](https://www.genspark.ai/privacy?ref=itsfoss.com) instead.\n\nThat policy states **text fed to the AI features gets passed to third-party providers**, including *OpenAI*, *Anthropic*, *Google*, *xAI*, and *ElevenLabs*, and that no API key is stored on your device.\n\nCurrently, GenOffice is available only for **Windows** (x64) and **macOS** on Apple Silicon. Intel Macs are not supported, and as you've probably guessed, neither is Linux.\n\n## Where's the Linux build?\n\nI did find [an open issue](https://github.com/genspark-ai/genoffice/issues/29?ref=itsfoss.com) (*very likely AI-generated*) that mentions a native Linux build, filed by a community member. It explains how shipping GenOffice for Linux isn't as simple as it sounds.\n\nAs of writing, there was no reply from [the lead developer](https://github.com/merrick-2002?ref=itsfoss.com) of GenOffice, so I wouldn't hold my breath for a Linux build anytime soon.\n\n**If you still want to try GenOffice**, you can grab installers for Windows and macOS from the [official website](https://genoffice.ai/?ref=itsfoss.com) or go through the source code on [GitHub](https://github.com/genspark-ai/genoffice?ref=itsfoss.com) to see if you can get a Linux build running yourself.\n\n**Suggested Read 📖: *** 6 Best Open Source Alternatives to Microsoft Office for Linux*\n\nEnjoyed this update?
