A closer look at Knowster

Knowster is an AI chatbot trained on a website: it reads the pages already written, re-reads them on a schedule so an answer never outlives its page, and answers visitors in whatever language they ask in, with setup in one line of code in about five minutes, lead capture, analytics, and a free trial that reads up to 20 pages with nothing stored.

Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.

When to choose Knowster

  • Website owners who want their site to answer questions while they sleep, around the clock.
  • Support, FAQ, lead generation, e-commerce, and SaaS teams that want answers from existing pages.
  • Teams that want unanswered questions to become to-do lines and askers to become dashboard contacts.

When to choose something else

  • Users who need more than 100 messages a month on the free plan, since Free covers one website, 100 messages a month, and 10 leads a month.
  • Users whose sources are PDF or Word only, since the Google Drive option reads Docs, Sheets, plain text, and markdown, while PDF and Word are not read yet.
  • Users who want a human support team, since Knowster answers from website pages rather than staffing support.

A practical starting workflow

  1. Enter the site address and let Knowster read the pages, with a free trial that reads up to 20 pages in usually under two minutes.
  2. Add one line of code to the site to go live in about five minutes.
  3. Let visitors ask in any language, capture leads, and review unanswered questions as to-do lines.

Check before committing

  • The guessed FAQ path returns a 404 page, so FAQ answers are cited to the homepage and pricing page.
  • Paid amounts appear without a named currency on the pricing page, Starter $39 and Pro $99 per month, so they are described as page observations and not recorded as structured facts.
  • The free trial demo disappears after 15 minutes with nothing stored, which is separate from the free plan.

Common questions
