If your support already lives in Intercom, Fin is the lower-friction choice and this page will not pretend otherwise. The integration you do not have to build is worth more than a feature comparison.
Fin moved to its own domain during 2026, intercom.com/fin now redirects to fin.ai, and the page that greets you there is not really a feature list. It is scale: 12,000 brands, a 76% average resolution rate, and Anthropic among the logos. If you are buying reassurance that the category works, they have more of it than anyone, and considerably more of it than we do.
The certifications are worth watching even if you are not buying Fin. ISO 42001 and AIUC-1 are AI-specific, they did not appear on vendor pages a year ago, and they are becoming the bar an enterprise security review asks about. We hold neither, and our security page says so in as many words rather than leaving you to notice.
Where the two differ is what happens when an answer is wrong. Fin does not show you which documents it retrieved or how they scored, so a wrong answer leaves you rewriting a source or adding an instruction and hoping. That is the gap this product exists to close.
Pick Fin if channel breadth, an existing Intercom estate, or an AI-specific certification decides it. Pick this if you expect to be debugging answer quality yourself, on a website, and want to see the retrieval stage while you do.
