A SiteGPT alternative with a free plan

What is SiteGPT?

SiteGPT's title is "Make AI your expert customer support agent". Its site describes a personalized chatbot "trained on your website content" that answers visitors 24/7. Listed features include:

• Training sources: website links and sitemaps, YouTube, files (CSV, TXT, PDF, DOCX, PPTX, MD), and Notion, Google Drive, Dropbox, OneDrive, Box and GitHub.
• Quick prompts (suggested starter questions).
• Weekly digest emails with usage and unanswered questions.
• Escalation to a human.
• Lead collection.
• Analytics with topic grouping.
• Integrations with Crisp, Slack and Zendesk.

Its pricing page listed several plans billed monthly or yearly, stated "there is no free plan", and offered a 7-day trial with a credit card required (checked 2026-10-14).

Why look for an alternative to SiteGPT?

• You want to start free, or try paid features without a card.
• Your knowledge is in documents, not spread across your website.
• You want to use your own AI key on any plan.
• You want industry templates with built-in guardrails.
• You want agency tools, such as client workspaces and report links.

How does InstantKnowledgeBot compare with SiteGPT?

When is SiteGPT the better choice?

• Your answers live across a very large website (more than 500 pages) that changes often, and you want crawling to keep the bot in sync.
• You need YouTube or cloud drive sources.
• You use Crisp, Zendesk or Slack and want the bot integrated there, with human escalation.

When is InstantKnowledgeBot the better choice?

• You'd like a free plan or a no-card trial.
• Your knowledge is a set of documents you control: FAQ, policies, price lists, handbooks.
• You want lead capture with instant email notifications and a simple pipeline.
• You want to bring your own AI key with no message cap from us.
• You build bots for clients and want workspaces and report links.

How do you move website content into InstantKnowledgeBot?

Enter your website's URL when you create the bot: import the whole site, a sitemap or single pages (up to 10 pages per import on Free, 50 on Starter, 200 on Pro and 500 on Agency). Then remove any pages you don't want the bot to use. You can also:

1. List the pages that answer most questions: FAQ, shipping, returns, pricing, contact.
2. Import each one as a single page, or save it as HTML or PDF.
3. Sign up free and add them to a new bot.
4. Test, then embed.

The step-by-step version is in create a chatbot from your website FAQ. Choosing pages yourself has an upside: old blog posts and outdated pages don't leak into answers.

Who is each tool built for?

• Companies whose answers live across a large, frequently changing website and that use Crisp, Slack or Zendesk will appreciate SiteGPT's crawling and integrations.
• Small businesses and agencies whose key answers fit in a set of documents (FAQ, policies, price lists) and who want to start free are InstantKnowledgeBot's focus.

What does day-to-day maintenance look like?

With InstantKnowledgeBot, you maintain the bot by maintaining its knowledge. When a file changes, replace it in the bot's Knowledge tab; when your website changes, click Refresh from website, or let paid plans re-import it automatically every week. The live bot updates as soon as the new content is in, and the embed code stays the same. Each week, check the knowledge gaps list for questions the bot couldn't answer, and add them. Every imported page is listed, so the bot only knows what you've chosen to keep.

What happens when a visitor needs a person?

SiteGPT lists escalation to a human. InstantKnowledgeBot shows your fallback message (for example your support email and phone number) and, with lead capture on Pro and Agency, collects the visitor's details so you can follow up. Each lead is emailed to you with the conversation.

Which questions should you ask before deciding?

• Is your knowledge mostly on web pages that change often, or in documents you control?
• Do you want to start free, or are you happy to begin with a card-required trial?
• Do you need helpdesk integrations such as Zendesk or Crisp?
• Would you like to run the bot on your own AI key?
• Do you manage bots for several clients?

Your answers usually make the choice clear. Either way, test both tools with the same 20 real questions before committing.

What should you check during a trial?

• Answers to your top 20 questions, including ones your content doesn't cover.
• Total monthly cost at your expected volume; see pricing.
• How each tool handles the limit, and what happens when a visitor needs a person.
