Most website chatbots answer from a generic script. SiteGPT builds its chatbot directly from your website’s content — pages, docs, PDFs, videos — so it can answer questions specific to your business without any manual training.
This review covers how SiteGPT works, what each pricing plan includes, how it compares to alternatives, and who it’s best suited for.
What Is SiteGPT?
SiteGPT is an AI chatbot builder that trains on your website’s content to create a custom support and engagement bot. You connect your site, SiteGPT crawls it, and the resulting chatbot can answer visitor questions based on your actual pages, product documentation, help articles, and uploaded files.
Unlike generic chatbots that require you to write out every Q&A manually, SiteGPT reads what your site already contains. When a visitor asks a question, the bot searches your content and replies with an accurate, context-aware answer.
Key use cases include:
- Customer support automation — answering FAQs, troubleshooting, and product questions 24/7
- Lead qualification — engaging visitors with relevant answers before they bounce
- Internal knowledge bases — training a chatbot on internal docs for team use
- E-commerce support — handling order questions, shipping policies, and product queries
SiteGPT works on any website platform. It integrates with WordPress, Shopify, Webflow, and others through a simple embed code. No developer is needed to set it up.
How SiteGPT Works
Training on Your Content
Setup starts by giving SiteGPT your website URL, sitemap, uploaded files (PDFs, Word docs), or YouTube video links. SiteGPT crawls and indexes the content, then uses it to train the chatbot. The bot answers only from what it has been trained on — it won’t fabricate information or pull from sources outside your content.
Training source options include website pages, sitemaps, PDF and Word files, YouTube videos, Notion docs, and Google Drive files (on Growth and Scale plans).
Real-Time Conversations
The chatbot widget appears on your site and handles visitor questions in real time. Conversations are powered by OpenAI models — the mini model by default, with GPT-4.1 available at a higher message cost. Responses stream in rather than appearing all at once, which keeps the interaction feeling natural.
Escalation to Live Agents
When the chatbot can’t resolve an issue, it can hand off to a human agent. The handoff is triggered by a button press — there’s no automatic escalation based on sentiment or complexity. Human agents can take over conversations in the SiteGPT dashboard.
Analytics and Feedback
SiteGPT tracks conversation volume, common questions, and message counts per period. Visitors can rate responses, and low ratings flag conversations for review. This feedback helps identify gaps in your training content.
Multi-Language Support
The chatbot can respond in multiple languages. If your site content is in English but a visitor asks in French, SiteGPT will attempt to answer in French using the underlying English training data.
SiteGPT Pricing Plans
SiteGPT has no free plan. All plans include a 7-day free trial. Prices below are monthly billing rates; annual billing reduces costs significantly.

Important: SiteGPT counts both the visitor’s question and the bot’s reply as separate messages. On the Starter plan’s GPT-4.1 allowance of 400 messages, that equals roughly 200 actual customer conversations per month. The mini-model allowance is 10x higher but produces less detailed responses.
Paid add-ons include: Remove SiteGPT Branding ($39/mo annual, $59/mo monthly), Extra 5,000 Messages ($39/mo annual), and WhatsApp integration ($39/mo annual).
SiteGPT vs. Alternatives

SiteGPT’s main advantage over Tidio and Landbot is the depth of site-content training — it reads and indexes your actual pages, not just a manually written FAQ. Its main disadvantage compared to Tidio is no free plan. Compared to Intercom, SiteGPT is significantly cheaper and simpler, but lacks the CRM, ticketing, and outbound messaging features Intercom provides.
Key Features of SiteGPT
Custom Chatbot Trained on Your Website
The chatbot’s knowledge base comes entirely from your content. It will not answer from general knowledge or make up information. If a visitor asks about a topic your site doesn’t cover, the bot says it doesn’t have that information — which reduces the risk of inaccurate responses.
Multiple Training Sources
Beyond website pages, SiteGPT can train on uploaded PDFs and Word documents, YouTube video transcripts, Notion pages, and Google Drive files. This means your chatbot can reference product manuals, knowledge base articles, and onboarding documents even if they’re not published on your website.
Auto-Refresh of Training Data
Website content changes. SiteGPT can automatically re-crawl your site on a schedule — monthly on Growth, weekly on Scale, daily on Enterprise — to keep the chatbot’s knowledge current. Starter plan users must trigger refreshes manually.
Integrations
Growth and Scale plans include integrations with third-party tools. The Scale plan adds Zendesk integration and webhook support. WhatsApp is available as a paid add-on. The Starter plan has no integration support.
Branding and Customization
The chatbot widget can be customized with your brand colors, logo, and name. The ‘Powered by SiteGPT’ label can be removed with a paid add-on ($39/mo annual). You can also set custom introductory messages and conversation starters.
Who Is SiteGPT Best For?
SiteGPT works well for:
- Small to mid-size businesses that want a chatbot to handle common questions without building a manual FAQ from scratch
- SaaS companies with documentation-heavy products where visitors frequently ask technical questions
- E-commerce stores on Shopify or WooCommerce that need 24/7 order, shipping, and product support
- Content-heavy sites like blogs or course platforms where visitors need help finding specific information
SiteGPT is less suited for teams that need built-in ticketing, outbound messaging, CRM, or a free tier to test before committing. For those use cases, Intercom or Tidio may be a better fit.
Pros and Cons of SiteGPT
Pros:
- Trains automatically on your website content — no manual Q&A writing
- Works across website platforms (WordPress, Shopify, Webflow, and others)
- Multiple training sources: PDFs, videos, Notion, Google Drive
- Real-time streaming responses feel natural in conversation
- Auto-refresh keeps the chatbot’s knowledge updated as your site changes
- Multi-language support without needing separate language versions
Cons:
- No free plan — only a 7-day trial
- Message caps can be tight: GPT-4.1 on Starter allows ~200 conversations/month
- Zendesk integration requires Scale ($429/mo monthly), not available on lower plans
- Escalation to human agents is manual — no automated routing based on urgency
- Branding removal costs extra on all plans
- Scale is a steep jump (3.3x the price of Growth) for one extra chatbot
Frequently Asked Questions
Does SiteGPT have a free plan?
No. SiteGPT does not offer a permanent free plan. All paid plans include a 7-day free trial. The lowest-cost entry point is the Starter plan at $39/month on annual billing or $59/month on monthly billing.
How does SiteGPT train on my website?
You provide SiteGPT with your website URL, a sitemap, or uploaded files. SiteGPT crawls and indexes the content, then uses it to build the chatbot’s knowledge base. The bot answers only from what it has been trained on — it won’t generate answers from outside your content.
What are SiteGPT’s message limits?
Message limits depend on the plan and AI model. The Starter plan allows 4,000 messages/month using the mini model, or 400 using GPT-4.1. Because both the visitor’s question and the bot’s reply count as messages, the GPT-4.1 allowance on Starter equals roughly 200 actual conversations per month. Higher plans have proportionally larger allowances.
Does SiteGPT integrate with Zendesk?
Yes, but only on the Scale plan ($429/month, $259/month on annual billing). Zendesk integration is not available on the Starter or Growth plans. WhatsApp integration is available on all plans as a paid add-on at $39/month (annual billing).
How does SiteGPT compare to Intercom?
SiteGPT is simpler and significantly cheaper than Intercom. Both train on your site content. Intercom adds CRM, outbound messaging, multi-channel support, and a full ticketing system — making it a better fit for larger teams. SiteGPT is the better choice if you only need a site-trained chatbot without the broader support suite.
Final Verdict
SiteGPT delivers on its core promise: a chatbot that knows your website. Setup is straightforward, the training process is automatic, and the responses are grounded in your actual content rather than generic AI answers.
The pricing structure has real limitations to be aware of — no free plan, tight message caps on the lower tiers, and a steep jump to Scale for Zendesk access. For teams handling moderate traffic, the Growth plan at $79/month (annual) provides a reasonable balance of features and capacity.
