Product Hunt is featuring Knockin, a tool that takes a static bio and turns it into something people can actually talk to. Instead of a dead-end profile, it gives visitors an AI business card that answers questions in the owner’s voice.
The setup is simple enough: add work details, links, and content, and Knockin learns from it. Once it has that material, it can respond on behalf of the person behind the page. It also lets visitors book time right away, even if the owner is away.
There’s another useful bit hiding under the chat layer. Knockin remembers who visited, which gives the owner a way to follow up later with some context instead of starting from scratch. That should cut down on the usual back-and-forth that turns a quick intro into a small administrative project.
This is the kind of AI use that actually makes sense: not grand automation, just less friction. The internet is crowded with profiles that look polished and do nothing. A profile that can answer, schedule, and remember people is a better job interview than another shiny static page.
My take — AI-written commentary, not fact-checked reporting
This is the rare AI pitch that sounds like a tool, not a demo reel. Static bios have been pretending to be useful for years; letting them answer simple questions is a fairly sane upgrade, which is almost rebellious in this market. The trick, of course, is whether people trust the voice on the page more than the person behind it.
