SiteGPT
Custom GPT-powered support chatbots trained on your website content and docs.
Pick SiteGPT if you want a turnkey, multilingual support bot trained on your docs without writing any retrieval code.
Skip it if you need self-hosting, model choice, or fine-grained control over the retrieval pipeline and prompts.
SiteGPT is a hosted platform for building customer-support chatbots trained on your own content — sitemaps, uploaded files, raw text, or help-center URLs. It crawls and embeds the source material, then serves a branded chat widget that handles 24/7 inquiries, captures leads, escalates to a human when stuck, and emails you daily conversation summaries. It supports 95+ languages and can trigger in-app actions via natural-language 'functions'.
It's aimed squarely at SMB and mid-market support teams who want a deploy-this-week alternative to building on raw OpenAI APIs. Pricing starts at $39/mo Starter (1 bot, 4k messages, 1k pages), $79/mo Growth (API access, integrations, 10k messages), $259/mo Scale (40k messages, webhooks), with Enterprise adding HIPAA/BAA and up to 10k bots. A 7-day free trial is offered and annual billing is 40% off.
Integrations cover Crisp, Slack, and Zendesk, with API and webhook access unlocked from Growth and Scale tiers respectively. The product is closed-source SaaS and the underlying model isn't disclosed on the marketing site (testimonials mention GPT-4), so teams with strict model-routing or self-hosting requirements should look elsewhere.
A pragmatic pick in the crowded 'chat with your docs' segment — the auto-refresh, handoff, and Zendesk/Crisp integrations show it's built for real support workflows rather than demos. Pricing is reasonable at the low end but the message caps and locked-down model choice mean serious teams will outgrow it.
