Word-faithful DOCX redlines and rendering without Word: a Rust engine with a Mac app, in-browser wasm, and Python and Node bindings. Scored against Microsoft Word.
Side-by-side diff for prose, not code: compare Word, LibreOffice and Markdown versions, follow moved text, see new and removed comments, restore tracked changes. AI review of the edits, or of a single document: problems marked in the text, fixes returned as tracked changes and comments in Word or LibreOffice. Two files, two folders or git.
kogo (校合) — local, layout-aware PDF diff for revisions: CJK-aware text, figures, equations, annotations, and style changes, via CLI, web UI, or Docker.
Compare two Word documents (.docx) into a native Track Changes redline — word-level diffs, image-faithful, self-verifying. Built with Kimi K3 Agent Swarm.
