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 the sample spectrum file, then provide the reported match list as text or upload the existing report. FTIR.fun will extract the reported Top-1 match and route the sample through the same ordinary search workflow.
View supported service types before submitting your request.
Compare two infrared spectra to determine if samples are compositionally consistent. Suitable for forensics, QC, and failure analysis.
Provide assignment and standard description of characteristic peaks for papers, projects, and reports.
Expert-assisted analysis for complex samples not easily identified by automatic search.
Includes IR testing consultation, case studies, and other customized technical support.
Commercial libraries remain essential for arbitration-grade work. FTIR.fun adds AI review to check whether the reported match is chemically correct and supported by the evidence. For routine R&D and QC, our library plus AI interpretation can complement, and in some workflows replace, a traditional library.
A subscription-based enterprise channel built around four commitments: confidentiality and compliance, efficiency, dedicated customer service, and unlimited sample volume.
