Knockin'

This is very suitable for me. I need to introduce myself and my project to many people.

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.

I’m curious about the voice feature. Can users make the responses more casual or professional depending on who is visiting?

Can I see which parts of my profile someone interacted with before following up?

Turning a bio into something people can actually interact with feels much more useful than a static list of links.👀

congrats on launch, I’ll try it out later, hope somebody will knock knock knocking at my door

As a freelancer, I literally say the same 3 sentences about my background on every single intro call lol. If this actually gets people up to speed before we even hop on, that's a real win. Also smart that you added a QR code + email signature, that's usually where these tools die, nobody actually shares them

Hey Product Hunt 👋 I’m He Zhao, founder of Knockin.Knockin' is live today, and we’re so excited to finally open the door! 🚪I started building Knockin after noticing how often a good introduction went nowhere. I’d meet someone interesting and exchange a profile or business card. The questions usually came later, after the moment had passed.I wanted every introduction to leave more room for curiosity.Knockin‘ is an AI business card that replies. It keeps your knowledge alive and ready to speak, even when you’re away.Add your work, links, content, and knowledge. You choose what Knockin‘ can use and set the boundaries for its answers.Visitors can:Ask questions about you and your workGet answers in your voiceDiscover what matters to themBook time with you directlyEvery question leaves useful context. Knockin‘ remembers who visited, what they asked, and what caught their attention. When you follow up, you can continue from where the conversation left off.Over time, those questions also show you how others see your work and what they want to understand better.You can share your Knockin‘ through a link, QR code, or email signature.We built Knockin’ for founders, freelancers, creators, salespeople, and anyone whose story deserves more space than a static bio can offer.👉 Create your Knockin‘, share it, and see what people ask.We’d love your feedback: what’s the first question you’d want your AI business card to answer?Thank you for celebrating this launch with us. The door is open. Come knock! 🚪
