Genspark开源GenOffice，免费无广告，只重写改动的段落，Word里版式不丢。
Genspark 将 GenOffice 以 Apache License 2.0 开源，覆盖 macOS 和 Windows 的 Docs、Sheets、Slides、PDF 四类应用，共五个 Electron 前端共享同一引擎层。其核心卖点是字节级保留的往返编辑：只有被修改的段落会重新生成为 OOXML 并拼回原文件，未改动部分保持原始字节，在 Word 中版式不丢。Sheets 部分采用开源 Univer 内核加自研 Rust xlsx 侧车。AI 功能需登录 Genspark 账号，按消耗积分计费。仓库目前标注为 Alpha 版本。
Genspark Open Sources GenOffice: A Free, Ad-Free AI Office Suite for macOS and Windows with Docs, Sheets, Slides, PDF
Genspark has open sourced GenOffice under the Apache License 2.0. It is an AI-native office suite for macOS and Windows, covering Docs, Sheets, Slides and PDF as five Electron apps over one shared engine layer. The notable engineering claim is a byte-preserving round trip: only edited paragraphs are regenerated as OOXML and spliced back into the original file, so untouched blocks keep their original bytes and layout survives in Word. Sheets pairs the open-source Univer core with an in-house Rust xlsx sidecar. AI calls route through a signed-in Genspark account and consume credits. The repository labels this an Alpha.
