DiffFind FEATURES
AI Document Comparison — Compare Documents with AI
Load the original and the revised version of a document and see exactly what changed. DiffFind highlights additions, removals, and edits, so you can review a revision without reading both copies side by side. Combine exact comparison with AI-powered semantic document comparison.
How it works
Run the comparison.
DiffFind finds every difference between the two versions.
Review the changes.
See changed, added, and removed content highlighted, then check each one against the source.

Structured data
Compare the structure of JSON, YAML, XML, and CSV files instead of raw lines.
Have a document in another format? Copy its text and paste it into the text comparison.
A comparison shows what changed. To understand whether a wording change affects meaning, add optional analysis with Semantic Diff, or locate a clause by idea with Semantic Document Search.
AI document comparison in DiffFind has two layers. A deterministic lexical comparison finds every exact difference. Optional semantic analysis then helps you understand whether the differences change the meaning, and does not replace the exact comparison. You can compare documents with AI across PDF comparison, Word, Excel, text, structured data, and API responses.
