  • Chatbase: 1 credit per reply on the default model (premium models cost more), so 1,500 credits. Extra credits $40 per 1,000; branding removal $99/mo.
  • SiteGPT: Quotas count visitor and bot messages, so about 3,000 messages on the default model. Extra 5k messages $39; branding removal $39/mo.
  • A “+” means the real bill is at least this much because higher tiers aren't public.

Choose Chatbase if

You want more channels (voice, WhatsApp, Instagram) and a built-in helpdesk, and your budget reaches the $150 tier.

Watch out for

  • Credit burn is confusing: a single reply can cost 2–6 credits depending on the model.
  • Steep jump from Hobby ($40) to Standard ($150) to get the helpdesk and API.
  • Removing branding costs an extra $99/mo; extra agents are $25/mo each.

Choose SiteGPT if

You have a very large site and want high page limits at a lower price, and you already use Crisp or Zendesk for humans.

Watch out for

  • No built-in human inbox; it relies on Crisp or Zendesk for handoff.
  • Branding removal is a paid add-on, even on the Scale plan.
  • No free plan, only a 7-day trial.
