DiffFind is a semantic search and diff tool that compares text and documents at multiple granularities (character, word, sentence, line, paragraph) while preserving context. It tracks additions, removals, and moved text, with optional AI analysis to explain changes, and supports multiple formats including JSON, YAML, XML, CSV, PDF, and Excel spreadsheets. The platform serves both non-technical users comparing contracts and documents, and developers via REST API and agent-ready functions.
