Unlike general-purpose AI such as GPT, FTIR.fun does not just generate plausible text: it ties peak assignments to published literature by DOI, cross-validates results against 130,000+ reference spectra and a knowledge graph, and states confidence and limitations when evidence is inconclusive. Available via web, REST API, and MCP server — reviewed and listed on Anthropic MCP Registry, Smithery, and MCP.so.
Upload a spectrum file or spectrum image to run library search and generate an FTIR interpretation report.
Search infrared spectra from our database by ID, IUPAC, CAS, or product name.
Upload a spectrum data file along with a report containing search results (with similarity scores), or directly paste the search results. The system will review and verify the reliability of the results, provide a confidence assessment, and analyze the characteristic peaks.
