Watch out: Free means the accounting; payments and payroll are charged, and that is where the business model actually is. 60 per-transaction fee rather than features, so on annual billing it only starts paying for itself somewhere above roughly 26 card transactions a month.

Questions
What is the best ai for small business?
There is no single answer, which is why this page lists 12 rather than one: ChatGPT, Claude, Canva Magic Studio, Zapier, Intercom, Gamma, Microsoft 365 Copilot, HubSpot, Wave, Bitrix24, Trello, Zoho Books. 6 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?
10 of the 12: ChatGPT, Claude, Canva Magic Studio, Zapier, Gamma, HubSpot, Wave, Bitrix24, Trello, Zoho Books. 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.
