Best free AI chatbots for websites, and where free runs out

Free chatbot plans are more generous than they were two years ago, and for a lot of small businesses one of them is genuinely the right answer. The trap is not that free plans are bad. It is that the tool you pick while you are free becomes the tool you are stuck with when you are not.

The three ceilings

Every free plan in this category limits you in one of three ways, and knowing which one applies to you is more useful than any feature comparison.

Conversation caps. The plan includes a set number of AI conversations per month. Cross the line and the AI silently stops, or you get billed. This is the most common model and the easiest to forecast.

Seat caps. Chat is free but only one person can answer. Fine for a solo operator, an immediate problem the moment you hire.

Feature gating. Everything works but the reporting is missing, so you cannot actually tell whether the bot is deflecting tickets or annoying people.

Where each one actually stops

Rather than list features, here is the point at which each free plan stops being the right tool.

Tidio’s free tier works until your AI conversations exceed the monthly allowance, at which point the Lyro agent stops answering. For a site with a few hundred visitors a day that can take months. For an ecommerce store in peak season it can take a week.

Freshdesk’s free plan is unusual in supporting unlimited agents, which makes it the best free option for a team rather than an individual. The limit here is that AI features live on paid tiers, so you get good ticketing and very little automation.

HubSpot’s free tier is best understood as a free CRM that happens to include chat. If you need contact records anyway, this is the highest-value free plan on the list. The ceiling arrives when you want marketing automation, and it arrives expensively.

The honest recommendation

Start free. Pick based on where you expect the ceiling to be rather than on today’s feature list, because switching costs are real once you have written a knowledge base and trained a bot on it.

And before you upgrade anything, check your actual numbers. A surprising number of businesses pay for AI conversation packs while resolving under twenty questions a month, which a well-written FAQ page would have handled for free.
