Knockin'
Turns your static bio into an AI business card that replies.
Knockin turns your bio into an AI business card people can chat with. Add your work, links, and content. It learns what you do and answers questions in your voice. Visitors can book time with you right away, even when you’re away. Knockin remembers who stopped by, so you know who to follow up with. This cuts down on back and forth and gives both sides more context before a call.
Do you also offer a printing service along with that? I mean, once someone is using your cards, exporting and printing the physical form would create the whole ecosystem.
