Getting a list of 50 "changes" in a document when 49 of them are just minor rewording is frustrating. Having the semantic diff actually separate a simple rewrite (like "retries three times" vs "makes three attempts") from a real meaning change like "30 seconds" becoming "3 seconds" is exactly what document reviewers need.

Every time I use an AI search tool on a PDF it just hallucinates an answer if it can't find it. The fact that DiffFind's semantic search defaults to being "silent when unsure" instead of making up a fake quote is a massive win. Being able to search by concept without actually sending the document to an LLM is exactly how this should work.
