02 / Tools

Practical tools that speed up your work.

Recover curves from images, look up reference spectra, and assign characteristic peaks — one account covers all three.

01

Extract curves from images

Turn spectrum figures from papers, reports or photos back into CSV data, with an overlay check before you download.

02

Find reference spectra

Search 320,000+ records by compound name, CAS number, formula, or spectrum ID.

03

Assign characteristic peaks

Start from peak positions and get functional groups, bond vibrations and traceable literature evidence, band by band.

03 / AI interpretation · Three-Axis analysis

Every search returns an analysis, not just a ranking.

Retrieval alone cannot tell you what a sample is. FTIR.fun couples ranked candidates with a constrained AI interpretation built on the Three-Axis framework — and similarity, direction confidence and evidence level are always reported separately, so the reasoning stays auditable.

AXIS 1 · RETRIEVALCoverage-gated candidate ranking. Reference spectra below 80% analytical-window coverage never reach the final ranking.
AXIS 2 · DIRECTIONMaterial-family direction with explicit confidence classes — entity-level match, library direction, or honestly unresolved.
AXIS 3 · EVIDENCEEvery characteristic peak mapped to functional groups and bond vibrations, with traceable literature citations.

04 / Discussion & human service

Stuck on a difficult spectrum?

Two independent channels for different data sensitivity: open discussion at zero cost, confidential delivery by the team.

FREE · PUBLIC

Public results discussion

Post your spectrum and sample background, and work through the interpretation with admins and other researchers.

  • Answered by admins or community members — no response-time guarantee
  • Posts are public and feed the community library and model training
  • Never upload confidential or NDA-restricted data
Open the discussion
PAID · CONFIDENTIAL

Human analysis service

Online Requirement: delivered by the FTIR.fun technical team within a confirmed turnaround — interpretation, verification and a formal report.

  • Submissions stay private: never published, never used for training
  • Committed turnaround with formal reporting
  • Built for corporate R&D, QC and confidential work
