About FTIR.fun

AI-Assisted Infrared Interpretation

FTIR.fun is an AI-assisted infrared spectroscopy platform designed to support scientific research, technical interpretation, and analytical workflows.

By combining continuously updated reference spectral resources, literature knowledge, and intelligent reasoning tools, FTIR.fun helps researchers, laboratories, manufacturers, and technical professionals perform more efficient infrared spectrum interpretation and preliminary evaluation.

FTIR.fun is intended to complement, rather than replace, established commercial spectral libraries, certified reference materials, and accredited laboratory procedures.

130,000+ Reference spectra

21,000,000+ Knowledge-graph facts

How FTIR.fun Works

Most spectral tools return a similarity-ranked candidate list and stop there. FTIR.fun cross-validates every result across three independent layers before producing an interpretation. When they align, you get a high-confidence report. When they don't — we say so, with explicit uncertainty annotation.

Reference Spectral Library

130,000+ spectra continuously updated from our team's experimental measurements, user-licensed contributions, and factual data extracted from public-domain sources — all legally compiled without copyright encumbrance.

AI Peak Reasoning

Proprietary AI assigns each peak to specific functional-group vibrations, verifies consistency with the matched structure, and flags anomalies. Every assignment links to the supporting literature by DOI.

Chemical Knowledge Graph

21,000,000+ relation facts connecting compounds, functional groups, spectral peaks, and published literature — providing a second independent check beyond similarity scoring.

Reference Database — Data Sources & Legal Status

The FTIR.fun reference database is a continuously evolving resource intended to support scientific research, technical interpretation, and preliminary analytical evaluation.

Reference spectra are compiled from three categories:

Experimental data measured by the founding team over decades of professional infrared spectroscopy practice.
Spectra and technical materials uploaded by users under the license terms specified in our Terms & Conditions.
Wavenumber and corresponding absorbance or transmittance values extracted from spectral images in published patent documents and other public-domain sources using proprietary image-processing technology.

Reference spectra are compiled from in-house measurements, user-licensed contributions, and factual data extracted from public-domain sources under applicable copyright law. See Data Use & Institutional Disclaimer for details.

Under international copyright law, facts — including quantitative spectral measurements such as wavenumber and corresponding absorbance or transmittance values — are not copyrightable expression. The Berne Convention (Art. 2(8)) excludes 'miscellaneous facts' from protection, and the TRIPS Agreement (Art. 10(2)) protects compilations of data only where the selection or arrangement constitutes an intellectual creation — not the underlying data itself. In the United States, the Supreme Court held in Feist Publications, Inc. v. Rural Telephone Service Co. (499 U.S. 340, 1991) that 'facts do not owe their origin to an act of authorship' and are therefore not copyrightable. Under China's Copyright Law (Art. 5), factual data and publicly issued patent documents are likewise excluded from copyright protection. Accordingly, extracting objective spectral measurements from publicly available patent images and other public-domain sources does not constitute reproduction of a copyrighted work.

Reference information provided by FTIR.fun should not be considered authoritative identification and should not be used as the sole or direct basis for arbitration, regulatory decisions, conformity assessment, or accredited laboratory conclusions. Some entries may carry less sample-preparation metadata than mature commercial databases.

Users are responsible for independently verifying analytical results. Enterprise confidentiality plans and zero-retention workflows are exempt from database incorporation.

Platform Recognition

Our MCP server has been reviewed and officially listed on the Anthropic MCP Registry, Smithery, and MCP.so. Claude, Cursor, Codex, and any MCP-compatible client can call FTIR.fun's spectral intelligence directly within their workflow.

FTIR.fun is also distributed as a LangChain tool on PyPI, an n8n community node on npm, and provides an OpenAPI 3.0 schema for GPT Actions and Dify.

Review and acceptance by these platforms is independent validation of our API design, documentation, and service reliability. View all integrations →

Payment & Financial Compliance

Payments on FTIR.fun are primarily processed through PayPro Global, a PCI DSS Level 1 certified payment platform and our authorized reseller and merchant of record, handling transaction processing, tax collection, and remittance across our served regions.

For regions where PayPro Global is unavailable, we employ alternative PCI-compliant channels to ensure every customer has a lawful, traceable payment path. Regardless of the processor, VAT, GST, sales tax, and other applicable levies are calculated and remitted in accordance with local regulations, and formal tax-compliant invoices are issued for every transaction.

Supported payment methods include major credit and debit cards, PayPal, Alipay, WeChat Pay, and wire transfer. Additional procurement documentation is available to institutional subscribers upon request.

Who We Serve & How to Use FTIR.fun

Our platform serves researchers, analytical chemists, technical professionals, educators, and students — from running a first IR spectrum to handling routine QC and failure analysis workflows.

FTIR.fun is available in three product forms to fit different working environments:

Online Platform — Upload spectra directly in your browser for search, AI interpretation, and report generation. No installation required. Supports 20+ instrument formats.
Instrument Terminal — A dedicated hardware device that connects to your lab instrument PC, enabling one-click spectral search and cloud AI analysis without exposing your internal network. Available as a subscription bundle with unlimited analysis.
MCP / Skill / API — Call FTIR.fun programmatically from Claude, Cursor, Codex, GPT Actions, or any custom agent via MCP server, REST API, LangChain tool, or n8n node. Bring spectral intelligence into your existing AI workflow.

We distinguish two use cases clearly:

Routine analysis — R&D, QC, failure analysis, and material identification. FTIR.fun's rapidly updated library with literature-supported interpretation complements — and in some workflows replaces — traditional library search.
High-stakes arbitration — Commercial libraries remain the gold standard. FTIR.fun adds an AI verification layer: does the top match make chemical sense? Are the peaks consistent with the proposed structure? Where is the uncertainty?

Reference library entries may contain less sample-preparation metadata than mature commercial databases. They are intended to support technical interpretation, not to serve as the sole basis for arbitration or regulatory submission.
