SupportAi vs SiteGPT
SiteGPT does what its name says: it turns your website into a chatbot. Setup is quick, the widget is clean and it answers questions from your pages well.
SupportAi covers the same ground and then keeps going into actions, channels, escalation and analytics. This comparison is for teams who started with a website bot and now need a support agent.

Knowledge: similar starting point
Both crawl your site, accept file uploads and answer from that content. Both let you customise the widget and capture leads. On knowledge alone they are close.
Doing things, not just saying things
SupportAi custom actions call your APIs mid-conversation and regex webhooks return exact data for order and reference numbers. Results render as status cards, buttons and forms. SiteGPT is focused on answering from content.
Channels and team
SupportAi includes Slack, WhatsApp and email on every plan with a shared inbox, rule-based escalation and human takeover. SiteGPT is primarily a web widget with basic hand-off.
Hosting and billing
SupportAi is UK/EU hosted and bills in GBP with VAT invoices. SiteGPT bills in USD.
Frequently asked questions
No. The first step is identical: paste your URL. Actions and channels are optional extras you add when you need them.
