More Than Spectral Matching
Delivering Detailed FTIR Interpretation Reports
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. FTIR.fun is also packaged as MCP and Skill integrations, callable from leading agent platforms such as Claude, Codex and 豆包 (Doubao) — extending professional FTIR analysis to a wider audience.
Start Analysis Task
Learn About FTIR In-Depth Interpretation →Upload a spectrum file or spectrum image to run library search and generate an FTIR interpretation report.
Find Spectra
Search infrared spectra from our database by ID, IUPAC, CAS, or product name.
Result Review
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.
