SiteGPT is an AI chatbot builder that trains on your website content. Its pricing is straightforward on the surface — four tiers — but the number that matters is what you'll actually pay each month once you pick a billing period and any add-ons you need.
SiteGPT plans at a glance
| Plan | Monthly billing | Yearly billing (per month) | Chatbots | Pages | Messages / month | Team members |
|---|---|---|---|---|---|---|

SiteGPT's message allowance is shared between a faster standard model and a more capable model: each plan gives you roughly ten times as many standard-model messages as advanced-model ones.
What's included on each SiteGPT plan
- Starter — manual content refresh and basic analytics.
- Growth — adds advanced analytics, API access, integrations (such as Slack, Messenger and Zendesk), an iOS app, rate limiting, monthly automatic refresh and a weekly digest.
- Scale — adds weekly automatic refresh, daily automatic scanning for new pages, webhooks and AI conversation insights.
- Enterprise — custom integrations, priority support and compliance options.
SiteGPT add-ons
| Add-on | Price |
|---|---|
| Remove SiteGPT branding | $39 / month |
| Extra 5,000 messages | $39 / month |
The branding add-on is the one to watch. If you don't want another company's name on your support widget, add $39 to whichever plan you choose.
What SiteGPT really costs per month
| Scenario | SiteGPT monthly | SiteGPT yearly (per month) |
|---|---|---|
| Starter, with SiteGPT branding | $59 | $39 |
| Starter, branding removed | $98 | $78 |
| Growth, branding removed | $168 | $118 |
| Scale, branding removed | $468 | $298 |
| Growth + 5,000 extra messages, branding removed | $207 | $157 |
How to pay less for SiteGPT
- Pay yearly. Yearly billing is the biggest saving — Starter drops from $59 to $39 a month, Scale from $429 to $259.
- Right-size your plan. Count your real monthly conversations before choosing. Many sites never use the full allowance of a higher tier.
- Keep the branding if you can. If a "powered by" badge doesn't bother you, skip the $39 add-on.
- Watch model usage. Advanced-model messages use up your allowance roughly ten times faster, so reserve them for complex questions.
- Compare alternatives with the same limits. If you need the same capacity for less, the next section shows one.

A cheaper SiteGPT alternative with the same limits
CustGPT's plans mirror SiteGPT's capacity — the same number of chatbots, pages, monthly messages and team seats — at a lower price, with branding removal included from Growth up.
| Plan | SiteGPT (monthly) | CustGPT (monthly) | SiteGPT (yearly, per month) | CustGPT (yearly, per month) |
|---|---|---|---|---|
| Starter | $59 | $49 | $39 | $29 |
| Growth | $129 | $119 | $79 | $69 |
| Scale | $429 | $419 | $259 | $249 |
CustGPT also offers a Basic plan at $19.99 a month (1 chatbot, 300 pages, 1,500 AI replies) for smaller sites — SiteGPT's cheapest plan is $59.
The gap widens once branding comes into it. Growth without branding costs $168 a month on SiteGPT and $119 on CustGPT — a saving of $49 a month, or $588 a year. On Scale the difference is $49 a month too ($468 vs $419).
CustGPT also includes premium-model replies on every paid plan (400 / 1,000 / 4,000 a month on Starter / Growth / Scale using Claude Sonnet 5, GPT-5.6 Sol or Gemini 3.1 Pro), and when those run out, replies continue on the standard model rather than stopping.
What you get with every CustGPT plan
- Website crawling, sitemap import, PDF/Word uploads and custom answers
- Answers with source links, and an honest fallback when the answer isn't in your content
- Actions that call your own APIs (order status, bookings) mid-conversation
- Human handoff with live replies from a shared inbox
- Lead capture with a leads inbox and CSV export
- Multilingual replies and a customisable widget
- Growth and Scale add Slack, Telegram, webhooks, the REST API, automatic refresh and a weekly digest

Is SiteGPT worth the price?
SiteGPT is a capable, established product, and if you rely on its iOS app or its Zendesk and Messenger integrations, it may be the right fit. If what you mainly need is an accurate AI agent on your website that hands off to your team and captures leads, you can get the same limits for less — and trying it for a week is the quickest way to compare answers on your own content.
