DiffFind – Semantic search and diff for text and documents

DiffFind launched a semantic search and diff tool that compares text and documents by character, word, sentence, line, or paragraph and tracks additions, removals, and moved text. The tool supports JSON, YAML, XML, CSV, PDF, and Excel (XLS/XLSX) comparison, offers optional AI analysis with cited facts verified against source documents, and exposes a REST API with agent-ready functions via a POST /v1/compare endpoint. DiffFind targets both non-technical users comparing contracts, invoices, budgets, and policy documents and developers integrating comparison into their own tools.
