Use tool ↗About Knowster
Knowster reads the pages a business has already published, plus optionally a Google Drive folder or manually written answers, and turns that into a chat widget that answers visitor questions on the same site. It replies in whatever language the visitor writes in, regardless of the source content's language, and can capture leads from the conversation. An analytics dashboard shows what visitors are asking, and paid plans add white-labeling. Installation is a single line of code and it updates automatically when the underlying pages change, so there's no separate re-training step. It's a solo-built product (the site credits one developer as creator); no company entity or country is disclosed.

Pros & cons of Knowster
A straightforward pick for a small business that wants a support widget trained on pages it already has, without a lengthy setup. The catch is it's a one-developer product with no disclosed company behind it, so there's no visible track record for support or uptime guarantees.
Pros
- One-line install with automatic re-training when pages change
- Answers in the visitor's language regardless of source content language
- Free tier with no credit card required
- Lead capture built into the chat flow
Cons
- Built and run by a single developer with no company entity disclosed
- White-labeling is locked behind paid tiers
- No API or integrations beyond the chat widget itself
Best for
- Small sites that want a Q&A widget without writing a separate knowledge base
- Businesses that get questions in multiple languages from one set of source pages
Not for
- Enterprises needing SLA-backed support or a named vendor for procurement
- Sites needing deep CRM or helpdesk integrations beyond lead capture
