About Document Compare
Document Compare is a private, in-browser document comparison tool. Drop in two files (or paste two snippets) and get a precise, professional diff: side-by-side and unified/inline views, word- and character-level intra-line highlighting, and a combined redline (insertions underlined, deletions struck through). It understands plain text, source code, Markdown, Microsoft Word (.docx), spreadsheets (.xlsx/.csv), HTML, RTF, and OpenDocument Text (.odt). For Word documents that contain tracked changes, Document Compare reconstructs a timeline of who changed what, and when. Above the results there are buttons to swap the two sides (handy when they were loaded backwards), clear both, and download the comparison as a unified .patch file — the standard format for code review tools and version control.
No account data, no uploads, no AI cost — all parsing and diffing happens locally in the sandbox, so your documents stay on your device.
The Fias AI assistant can drive the app for you: pasting text you give it into either side, swapping or clearing the sides, switching between the split, inline and redline views, changing the comparison options, and downloading the patch. It deliberately cannot see your documents, the differences, or the patch — the assistant runs on Fias servers, and sending it your content would break the promise that your documents never leave the page. It is told only measurements: how many lines, words and characters were added or removed, and where the changed blocks sit (how many there are, how big the largest is, and which line ranges). So it can tell you how big a change is, whether it is one block or scattered, and where to look — but never what the change says.
