It was only a while back that I came across OnlyOffice, a free document suite that made it easier to say goodbye to Microsoft 365.

Although other Microsoft Office alternatives, such as LibreOffice, existed, they never offered the level of compatibility I experienced with OnlyOffice.

Recently, however, I came across a free, open-source office suite that let me drop OnlyOffice for good: GenOffice. While at it, this free solution has also become my go-to AI office suite.

GenOffice is the office suite that Genspark built backwards

AI first, editor second, and I noticed immediately

For starters, GenOffice is a free, AI-native desktop office suite that Genspark built from scratch. It is currently available for Windows, macOS, and Linux and offers smooth compatibility with Microsoft Office files. The office suite packs enough utilities to get all your documents ready from a single interface.

It is called AI-native because AI-powered features for creating and editing documents are built into the core of the office suite rather than added as an afterthought. The result is an AI-first document suite that works with most workflows. I’ve been using this suite for all my document creation needs for a while, and I haven’t thought of going back to OnlyOffice or Microsoft Office.

These tools are called AI Docs, AI Sheets, AI Slides, AI Markdown, AI HTML, and AI PDF. As you’d guess from the name, you can use them to edit or create different kinds of documents — with the help of AI, of course. The core editing features are free, and you can power all AI features in a few ways.

It is important to note that GenOffice doesn’t require you to pay for AI features. Instead, I found plenty of room for flexibility. You can either get Genspark AI credits or bring your own model using a platform like OpenRouter.

The AI lives inside the document, not beside it

It works with the models you bring, including local ones

As far as setup goes, I can connect GenOffice to popular platforms like OpenAI or Anthropic, or to a local AI via an API endpoint. This flexibility means I can use free models to power the document AI. More importantly, if I don’t like my data going to third-party servers, I can always use a local LLM.

Once this setup is complete, I can enjoy the AI-native document experience that GenOffice offers. You get to see the AI integration of GenOffice the moment you open the app. There’s a sidebar on the left that serves as an AI Chat interface, where I drop my prompt to create or edit documents.

For instance, I can ask GenOffice AI Slides to create a deck on a topic, and it just does that. Depending on the model in use, the app may also ask questions to improve the output. You can also see dedicated buttons for AI Beautify, AI Fact Check, and AI Image. Similar features are built into each GenOffice component — and they make all the difference.

As you’d expect from an AI-first office suite, GenOffice does offer additional AI options. For instance, you can install a skill on your desired CLI or set up an MCP server so that you can invoke GenOffice capabilities from Terminal. An MCP server also means I can build impressive documents using GenOffice without connecting an AI provider to the office suite.

GenOffice’s six apps hide inside one clean shell

No ribbons, no clutter, just tabs that make sense

All these AI features are great only when the editor is worth using. Fortunately, GenOffice has done a better job of optimizing the UI for modern use than OnlyOffice has. As a result, I can manage all my documents from a single app thanks to the tabbed interface. The main page also serves as a hub that lets me search not only file names but also their contents.

Each tool built into the GenOffice suite also deserves a lot of appreciation. They are well-designed and include most of the features you’d expect from their labels. Sure, you may not find all the minute features you’re familiar with in Microsoft Office. But it won’t be a deal-breaker for most people.

Equally impressive are some lesser-known office tools built into GenOffice. For instance, the AI PDF tool makes it effortless to create new PDF documents or edit existing ones. Similarly, the AI HTML tool is a great option for creating UI designs or even writing content. The AI Markdown editor also comes in handy if you need a rather simplified space to write down things.

Unlike OnlyOffice, GenOffice takes a slight diversion from the typical user interface you’re familiar with in Microsoft Office, but that’s for good reason. You finally get a UI that is smooth and performance-friendly. Overall, GenOffice has been offering a streamlined office experience without requiring a hefty subscription or asking to live with a clumsy user interface.

It’s still in alpha, and you should know

Despite how great my experience with GenOffice has been, I must mention that it is still in alpha stage. It means you might come across minor bugs, but the developers continue to add new features into the mix. Also, GenOffice doesn’t offer mobile apps yet. Nevertheless, the fact that it is free, ad-free, and mostly open-source is reason enough to ditch both Microsoft Office and OnlyOffice in favor of this modern office suite.
