Choose Replyflow if…
- You want more than answers — buying-intent scoring, lead capture and HubSpot sync built in

- You want voice in the widget and calendar booking across five providers
- You prefer credit-based pricing over per-message quotas
Choose SiteGPT if…
- You need very large page counts — SiteGPT's Scale plan covers up to 50,000 pages
- You want its Zendesk AI Agent or the iOS app for answering on the go
- You want daily automatic content re-scans on the top plan
- Your budget starts under $40/mo and lead capture alone is enough

What SiteGPT does well
SiteGPT does the core job — answer visitor questions from your site content — simply and at a fair price. Lead capture is wired in by default, the page limits are generous (up to 50,000 pages on Scale), and touches like the iOS app and the Zendesk AI Agent show a team focused on support workflows.
For content-heavy sites that mainly need accurate self-serve answers and a list of captured emails, it's a sensible pick.
Where Replyflow is different
Replyflow starts where Q&A ends. Every conversation is scored for buying intent, so you know which visitor is browsing and which is evaluating with budget. Qualified leads land in HubSpot with the transcript and intent attached, and your team gets a Slack ping while the visitor is still on the page.
It also acts: a hosted MCP server generated from your OpenAPI spec (or your own MCP servers) lets the agent look up orders, check accounts and book meetings across Cal.com, Calendly, Google, Outlook and Microsoft Bookings — capabilities SiteGPT largely leaves to Zapier glue.
Frequently asked questions
Is Replyflow a good SiteGPT alternative?
Yes, if you want the chatbot to produce pipeline rather than only answers. Replyflow adds buying-intent scoring, HubSpot sync, Slack alerts, voice, calendar booking and MCP-based actions on your own API. If you only need Q&A plus basic lead capture on a large site, SiteGPT covers that well.
How does Replyflow pricing compare to SiteGPT?
SiteGPT charges per message quota: $39/mo for 4,000 messages up to $259/mo for 40,000, with branding removal a $39/mo add-on. Replyflow uses AI credits: Starter $49/mo, Growth $199/mo with branding removal included — and 500 free credits, no card, to start. As of August 2026.
Does SiteGPT score leads like Replyflow?
SiteGPT captures leads but doesn't advertise buying-intent scoring. Replyflow scores every conversation for intent and syncs the score to HubSpot, so sales can prioritise the visitors most likely to buy.
Can I switch from SiteGPT to Replyflow?
Yes. Both train on your website, so switching means pointing Replyflow at your domain and swapping one script tag. The 500 free AI credits let you compare answers before you move.
