A SiteGPT alternative that has one price per answer
The headline allowance is on the cheaper model. Switch to the better one and each message costs ten, so 4,000 becomes 400 — and the logo is another $39 a month.

Is this a drop-in replacement for SiteGPT?
Not in every respect, and it would be dishonest to say so. Volume on a budget model. If the cheaper model answers well enough for your site, SiteGPT gives you more messages per dollar than we do. What it replaces is the part that answers customers' questions from your own pages, at a flat price.

$59 a month for 4,000 messages, $129 for 10,000 and $429 for 40,000, on its cheaper model. Messages on the better model use 10 times the credits, and removing the branding is $39 a month. Checked October 2026 against their published pricing — worth confirming, since prices move.
