DiffFind helps business users, writers, and developers review changes between document versions, text, and data without relying on manual side-by-side checks. It compares plain text, Word and PDF files, Excel workbooks, and structured formats such as JSON, YAML, XML, and CSV. Results can show additions, deletions, and moved text at the character, word, sentence, line, or paragraph level; structured data changes are shown in context. The comparison is deterministic and works without AI. Optional semantic analysis helps explain whether wording changes affect meaning and highlights potentially material changes. Semantic Find can locate passages by concept when a document uses different words from a search query. Developers can also compare API requests and responses using URLs or cURL commands, or automate comparisons through a REST API.
