AI customer support agents
An AI support agent answers your customers before a person has to, and the good ones also act: refunds, order changes, account fixes. The real split is where it lives. Zendesk, Gorgias, Freddy AI, Kustomer and Gleap build the agent into their own helpdesk. Intercom Fin and Forethought plug into the helpdesk you already have. Decagon, Sierra and Ada are enterprise platforms you buy through sales. Most now bill per resolution or conversation, not per seat, so compare what counts as an outcome before you compare prices. 10 tools, in the order they appear in the directory. This is not a ranking.
