Knowster reads a website's public pages (and optionally a Google Drive folder or hand-written answers) and answers visitor questions from that content, in the language the visitor uses. Unanswered questions are logged and visitors who ask can be captured as leads. The widget is added with a single script tag and is configured from a web dashboard. Plans run from a free tier to a $299/month Scale plan, with message and lead limits per plan.
