The short answer
One reads more. The other does more with each visitor.
Choose AI Chat Bot if you run a local business with a normal-sized website and the job is turning visitors into booked customers. Every plan includes everything: lead emails with a reminder and a backup contact, real free times from Google Calendar, a webhook to your CRM, rules written for your trade, and a Results screen that measures what the assistant adds. It holds to your facts by a check, not only by an instruction, and there's a Free plan to start. Starter is $19 a month for 1,500 customer messages.
Stay with SiteGPT if you need it to read thousands of pages, YouTube videos or a Notion workspace, if your team wants to take over chats live from a shared inbox or an iPhone app, or if you need WhatsApp, Messenger, Slack or Zendesk, an API, or a SOC 2 Type II report. SiteGPT has all of those. We don't.
How we compared
We make AI Chat Bot. We compared it with SiteGPT using SiteGPT's pricing page in both its monthly and yearly views, its plans and limits reference, its help docs on answers, leads, human support and billing, and its security page, all read on October 1, 2026, and our own product as it works today. We didn't buy a SiteGPT plan for this page. SiteGPT has few public reviews (12 on G2 when we looked), so we quote one and say so. Where SiteGPT is the better pick, we say that too.
Why people switch
Why people look for a SiteGPT alternative
“4k messages” can mean 200 answered questions
SiteGPT counts the visitor's message and the chatbot's reply separately, so one answered question uses 2 messages. One GPT-4.1 message uses as much as 10 GPT-4.1 mini messages, and its docs say new chatbots start on GPT-4.1 (choose a model). On that default, Starter's 400 GPT-4.1 messages cover 200 customer questions.

Staying on your content is an instruction
SiteGPT's own help docs are candid about this: “answer only from your content” is “guidance, not a hard block”, and the model can still use general knowledge it already has. Clear instructions reduce that, they say, but can't remove it fully.
The lead tools sit on bigger plans
The leads webhook for a CRM needs Scale, at $429 a month (plans and limits). The iPhone app needs Growth, and Starter refreshes your content by hand only. A May 2026 G2 review also wished for deeper Zapier and HubSpot integrations. Removing “Powered by SiteGPT” is a $59 add-on.

No free plan, and nothing to fall back on
SiteGPT has no free plan, and its seven-day trial needs a card. Cancel during the trial and the chatbot stops at once. When a paid subscription ends, the chatbots stop answering and SiteGPT schedules their conversations, documents and leads for deletion after 30 days.

Side by side
AI Chat Bot vs SiteGPT, row by row
| Feature | AI Chat Bot | SiteGPT |
|---|---|---|
| Starting paid price | $19 a month ($17 billed yearly) for 1,500 customer messages and 1 website. | Starter, $59 a month, or $39 a month billed yearly ($468): up to 4,000 GPT-4.1 mini or 400 GPT-4.1 messages, 1 chatbot, 1 member. Growth is $129 ($79 yearly), Scale $429 ($259 yearly). |
| What you pay for, and what happens at the limit | One customer message answered. Past your allowance it keeps answering in shorter form and keeps taking leads until the 1st. No overage charge; a top-up of 2,000 messages for $20 is optional. | The visitor's message and the reply each count, so a question and its answer use 2. A GPT-4.1 message counts as 10. At zero the chatbot keeps answering, the dashboard is covered until you buy more, and 5,000 extra messages are $59 a month (plans and limits). |
| Free plan and trial | Free for ever: 100 customer messages a month. A 7-day trial of 200 messages first, no card. Cancel a paid plan and you drop to Free, still answering. | No free plan. A seven-day trial on each self-serve plan, card required. Cancelling a trial stops the chatbot at once (billing). |
| How answers stay accurate | Answers come only from facts read from your pages and documents, your own answers, or your page's wording quoted exactly, and each reply shows what it used. A factual answer with nothing behind it is blocked and passed to you instead. | Finds the passages that most closely match the question and writes an answer from them, with your fallback message when nothing matches. Its docs call the stay-on-your-content rule guidance that clear instructions reduce but can't remove (how answers work). |
| When it can't answer | Says so, takes the visitor's name and contact, and emails you the question. A Talk to a person button sits under every reply. | Replies with your fallback message. With human support on, a button asks for a person, the owner gets an email, and your team replies or takes over from Chat History, or the iPhone app from Growth (human support). |
| Lead capture and alerts | Asks in the conversation for a name, a way to reach them and what they need. An email in seconds with a one-line summary, one reminder after 5 minutes, then your backup contact is told. Urgent leads are marked urgent. | A form inside the chat (email always required), shown on interest, on a gap or after a set number of messages. An email to your team for each new lead, and iPhone pushes from Growth (collect leads). Reminders and a backup contact: not published. |
| Bookings | Sends customers to the booking page you already use, or offers your real free times from Google Calendar and books them into your diary. | Your booking-page link (Calendly, Acuity or others), shown after the visitor fills in the lead form. |
| Set up for your kind of business | Pick one of 25 business types, each with its rules already written: what it must never promise, what counts as urgent, which details to ask for. | Nine lead-form templates (Dental Clinic, HVAC Services, Legal Services, Real Estate and five more) that preset the form fields and booking. Rules about what not to say go in instructions you write. |
| What it learns from, and staying current | Your key pages in about a minute, up to 40 after signup, up to 50 pages kept, plus 20 PDF, Word or text files. Re-reads weekly, or daily on Growth and Pro, and emails you when a price it quotes changes. | 1,000 pages on Starter, 10,000 on Growth, 50,000 on Scale (a page is 2,500 characters), from websites, files, YouTube, Notion, Google Drive and more. Manual refresh on Starter; auto-sync monthly from Growth, weekly on Scale. |
| Checking answers before customers see them | A Test page with the questions your customers ask, one-step corrections, a preview of what an edit changes before you save it, and a To check list of facts that disagree and answers it wasn't sure of. | Review chat history, fix answers with custom responses, and from Growth see a list of unanswered questions. |
| Sending leads to your CRM | A webhook to Zapier or Make on every plan, with guides for HubSpot, Pipedrive and Salesforce. Leads and conversations export as a spreadsheet. | Lead emails and CSV export on every plan. The leads webhook from Scale ($429 a month), and no built-in CRM connection (send leads). |
| Measuring results | Results compares visitors who saw the assistant with a held-back group who didn't, plus customers' ratings of their chats. | Totals on Starter; trend charts, CSV export and a weekly digest from Growth; topics, sentiment and outcomes from Scale. |
| Channels, AI models and security | Your website (one line of code or the WordPress plugin) and a hosted chat page. One AI model, chosen and tested by us. No SOC 2, HIPAA agreement or SSO yet (security). | Website and hosted page, plus Messenger, Slack, Google Chat, Crisp and more from Growth, Zendesk from Scale, WhatsApp as a $59 add-on, and an API. GPT-4.1 or GPT-4.1 mini. SOC 2 Type II; HIPAA agreement on Enterprise (security). |
| Best fit | Small and local businesses that want visitors answered from their own facts, every lead followed up, bookings in the diary and every feature on the plan they can afford. | Businesses with big sites or document sets, teams that want to take over chats live, and companies that need more channels, an API or SOC 2. |

Where we're the better pick
Where AI Chat Bot is the better choice
Every feature on every plan, counted per customer message
A message is one customer message answered, and the reply doesn't count again. The webhook, Google Calendar, daily or weekly re-reads and Results come with every plan, so the price you see is what the features cost. At 1,500 customer messages a month, ours is $19; the same volume is $59 on SiteGPT's smaller model and $365 on its default one. Plans.
Your facts are enforced, not requested
Every reply has to rest on a fact from your pages, your documents or an answer you wrote, and a factual reply with nothing behind it is stopped and handed to you. You can watch this on the Test page before a single customer sees it. How answers work.
A lead that waits gets chased
Both products email you a new lead. Ours adds a one-line summary of what they want, one reminder after 5 minutes if you haven't opened it, then a message to your backup contact, and urgent leads marked urgent. Missed callbacks are where small businesses lose jobs. Lead alerts.
Real appointment times, not only a link
Connect Google Calendar and the assistant offers your actual free times inside the chat, then writes the booking into your diary and tells you. Or keep the booking page you already use. Bookings.
Rules for your trade, already written
SiteGPT's templates set up the lead form. Ours set up behavior: a dentist's assistant never gives clinical advice, a roofer's never promises what insurance pays, a law firm's says early that it isn't a lawyer. All 25 business types.
Where they're the better pick
Where SiteGPT is the better choice
Much bigger knowledge
SiteGPT's Starter covers 1,000 pages of 2,500 characters each, Scale 50,000, from websites, files, YouTube, Notion, Google Drive, GitHub and more. We read up to 50 pages and 20 documents per website, which suits a local business site but not a large catalog or help center.
Your team can take over live
With human support on, your staff reply inside the chat or take a conversation from the AI in SiteGPT's dashboard, and from Growth in its iPhone app. We have no shared inbox: after the alert, you reply by phone or email.
More channels, an API and model choice
SiteGPT answers on Messenger, Slack, Google Chat, Crisp, Zendesk and WhatsApp (some by plan or add-on), has an API, CLI and MCP server, and lets you pick GPT-4.1 or GPT-4.1 mini. We answer on your website and a hosted chat page, with one model.
Security paperwork and reviews
SiteGPT reports a SOC 2 Type II examination and GDPR certification, offers a HIPAA agreement on Enterprise, and holds 4.9 from 12 reviews on G2 (October 1, 2026). We're new: no SOC 2 report and no customer reviews yet.
Everything AI Chat Bot does
What you get, on every plan
Answers you can trust
Answers from your website and documents
Paste your address and it reads your key pages in about a minute, and up to 40 once you sign up. Add price lists or brochures as PDF, Word or text files, and write your own answers to common questions. How it works.
Says when it doesn't know
An answer has to come from your facts or quote your own pages word for word. When nothing covers a question, it says so and passes it to you instead of guessing. Custom chatbot.
Stays up to date
It re-reads your website every week, or every day on Growth and Pro, and emails you when a price or policy it quotes has changed.
Answers in your customer's language
It replies in the language the visitor writes in, from the same facts, and the chat's buttons switch to that language too.
Leads, bookings and handoffs
Captures the lead
It answers first, then asks for a name, a way to reach them and what they need, and keeps the full conversation with the lead. Lead generation.
Email alerts in seconds
Each lead arrives by email with a one-line summary of what they want. Unanswered, you get one reminder after 5 minutes, then your backup contact is told. Urgent leads are marked urgent. Lead alerts.
Books appointments
It sends customers to the booking page you already use, or connects to Google Calendar and offers your real free times. Bookings.
A person is always one tap away
A Talk to a person button sits under every reply. Asking for you sends you their question and details at once. Human handoff.
Sends leads to your CRM
A webhook passes each lead to Zapier or Make, and from there into HubSpot, Pipedrive, Salesforce or anything else. CRM guides.
Control and proof
Check answers before customers see them
The Test page shows its answers to the questions your customers ask. Fix one in a step, and preview what an edit changes before you save it. Test and correct.
Rules for your kind of business
25 business types each come with their own rules: a roofer's assistant never promises what insurance pays, a dentist's never gives clinical advice. Business types.
Results measured against a control group
Hold back a small share of visitors from seeing it, and Results compares the two groups, so you see what it adds rather than every lead it touched. Customers' ratings of their chats show there too. Results.
Your data, yours to take
Download your leads and conversations as a spreadsheet, choose how long they're kept, and delete your account yourself. Security and privacy.
On your website
One line of code, or a plugin
Paste one line into any website, install the free WordPress plugin, or share your own chat page link. Chat widget.
Never in the way
It never pops open by itself, takes your colors, and goes full screen on phones so it's easy to use.
Answers around the clock
Evenings and weekends get the same answers as office hours, and urgent leads can wake you if you want them to. After hours.
Plans: Free for ever with 100 customer messages a month, after a 7-day trial of 200. Paid plans from $19 a month, no setup fee, cancel any time. Compare plans.

Switching
How to switch from SiteGPT
Paste your website into the demo
It reads your key pages in about a minute and you can chat with it straight away, with no account. Sign up and it reads up to 40 pages in the background. How it works.
Bring over what SiteGPT knew
Upload your price lists and brochures as PDF, Word or text files, and copy your SiteGPT custom responses and text snippet into your own answers, which outrank your website. YouTube, Notion and Drive sources, instructions, chat history and the iPhone app don't carry over. Export your SiteGPT leads as CSV first.
Set alerts and bookings, then test
Choose where lead emails go and add a backup contact, paste your booking link or connect Google Calendar, then check the answers on the Test page and fix any in a step. Bookings.
Swap the code, then cancel
Remove SiteGPT's embed code, then paste our one line or install the WordPress plugin. A paid SiteGPT plan keeps working to the end of its billing period after you cancel, so you can run both while you check.
Questions
Questions buyers ask
Is AI Chat Bot a good SiteGPT alternative?
Yes, for a local or small business whose website is a few dozen pages and whose goal is leads and bookings. If you need thousands of pages, live takeover or more channels, SiteGPT is the better fit. The quickest test is to try ours on your own site and ask it something your pages don't say.
Is SiteGPT free?
No. SiteGPT has no free plan; it offers a seven-day trial that needs a card, and a demo bot trained on its own website. AI Chat Bot has a Free plan of 100 customer messages a month that keeps your assistant running for as long as you use it.
Does AI Chat Bot answer in other languages, like SiteGPT?
Yes. It replies in the language the customer writes in, from the same facts, and the chat's buttons switch to that language too. SiteGPT lists 95 languages; we don't keep a list, so try your customers' languages in the demo before you decide.
Can AI Chat Bot read as much as SiteGPT?
No. We keep up to 50 pages and 20 documents per website, chosen from your sitemap or added by address. That covers the services, prices, areas and policies of most local businesses; a shop with thousands of product pages needs SiteGPT or a similar tool.
Can my team reply inside the chat, as with SiteGPT?
Not today. The assistant hands the conversation to you by email with the customer's question and details, and you call or email them back. If live chat with your staff matters most, SiteGPT's takeover and iPhone app are the better fit.
What happens if I stop paying?
On ours, you move to the Free plan: the assistant keeps answering 100 customer messages a month in full, and your leads and conversations stay yours to download. On SiteGPT, the chatbots stop answering when the subscription ends and their data is scheduled for deletion 30 days later.
