GenOffice, released by Genspark under the Apache 2.0 license, is a desktop office suite covering documents, spreadsheets, presentations, PDFs and markdown for macOS, Windows and Linux, according to the project's GitHub repository.
The suite reads and writes native .docx, .xlsx and .pptx files with byte-preserving edits meant to keep files fully compatible with Microsoft Office, the repository states. It includes local PDF-to-Word, PowerPoint or Excel conversion with OCR for scanned documents, and five integrated applications: Docs, Sheets, Slides, a PDF editor and a markdown editor.
AI editing is built in as what the project calls a first-class workflow rather than an add-on, with a bring-your-own-key option supporting Claude, OpenAI, Gemini and other model providers, according to the repository. Document editing works fully offline; AI features require a network connection.
The project has drawn 4,650 stars and 690 forks since its late July repository creation, built primarily in TypeScript with Rust components for the spreadsheet engine. Enterprise modules are kept in a separate, reserved package, but the core suite carries no paid tier, the repository states.
A free, self-hostable Office alternative is not new. One built from the start around editing files with an AI agent instead of a mouse, and licensed so a company can run it entirely on its own infrastructure, is a more specific pitch to any builder wary of routing documents through someone else's cloud AI feature.
