Strong fit. The free CRM is genuinely usable rather than a demo, and the AI reaches across contacts, email and content once you pay.

Basic Vibe+ plan −34%
Watch out: Free is generous and the interface is dense in proportion. Paid plans are priced per organisation with a fixed number of users included rather than per seat, so the bundle is what to compare.

Watch out: 99 a Fin outcome on top of every seat, so cost scales with volume rather than headcount. The entry price advertised is a new-customer offer against a $29 to $39 seat, and Fin can be bought on its own with no seats if you already run a helpdesk.

Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for customer service?
There is no single answer, which is why this page lists 6 rather than one: Intercom, Zapier, ChatGPT, Claude, HubSpot, Bitrix24. 3 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
5 of the 6: Zapier, ChatGPT, Claude, HubSpot, Bitrix24. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
