What the AI actually costs: published, in the open
Most chat vendors hide the model cost inside credits, multipliers, and per resolution fees. One rival charges US$0.99 for every resolved chat. Another charges about US$0.65 to US$0.78 per AI conversation. Here is what the raw AI actually costs at published API rates, November 2026:
Assumptions, stated plainly: each message carries about 1,500 input tokens (the visitor question plus the retrieved passages from your site) and about 250 output tokens, across a 10 message conversation. Indexing your whole site costs under US$0.01 one time at published embedding rates of US$0.02 per million tokens. Sources are listed at the bottom of this page.
The same math at different conversation lengths
Read that last column again. A full month of Growth plan conversations, every one answered by a capable model, costs roughly a dollar in AI fees. Even the premium model at full volume stays under ten dollars. Anyone charging per conversation or per resolution is charging for the metering, not the AI.
And it gets cheaper as scripts take over
Indexing is a one time cost of under a cent, and weekly refreshes cost the same order of magnitude, because only changed pages are re indexed. Then Script Builder starts eating the volume: if your top action is 40% of conversations and it moves to an approved script at zero inference cost, your monthly AI bill falls by roughly that share, from about a dollar to about sixty cents in the example above. The curve only bends one way, month after month, as the learning loop promotes more repeat actions into scripts.
The conclusion: a conversation costs between US$0.003 and US$0.03 in AI fees, and even the premium model stays under three cents. That is why our pricing is a flat monthly fee in Canadian dollars with a clear conversation allowance, instead of credits that burn at different rates depending on which model answered. And it is why we never route your visitors to a free tier: free API tiers can use conversation content to improve the provider products, which is no place for your customers names and phone numbers. Your chats run on paid tiers with no training on your data.
