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.
Use this when you already have a library search report and only need FTIR.fun's downstream AI interpretation.
Provide at least one reported match. A full Top15 candidate list is better, but a clear Top1 result is acceptable.
The same report must also contain the sample peak list or peak table in cm-1. Without peaks, KG and related-literature analysis cannot proceed.
The API accepts pasted report text or a report file such as PDF, DOC/DOCX, TXT/CSV, or an image exported by the instrument software.
If the uploaded report does not contain both the reported results and the peak table, the API stops and returns the missing requirements instead of generating a report.

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 test whether the reported match is chemically defensible. For routine R&D and QC, our library plus AI interpretation can complement, and in some workflows replace, a traditional library.
