Genspark open-sources a free AI office suite for Mac and Windows

Genspark released GenOffice under the Apache 2.0 license, an AI-native office suite covering documents, spreadsheets, slides, and PDFs as five Electron apps sharing one engine. It claims byte-preserving edits, so untouched parts of a file keep their original formatting, and uses an in-house Rust sidecar for spreadsheets. The project is currently in alpha, and AI features require a signed-in Genspark account that consumes credits.

Why it matters: A free, open-source Office alternative with AI built in directly challenges Microsoft 365 Copilot and Google Workspace's AI add-ons, especially for users who want local apps rather than browser tools. The byte-preserving editing approach also targets a real pain point in AI-assisted document editing, where round-tripping through AI often mangles formatting.
