Launched this week
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.
Knockin'
@busmark_w_nika Yes, absolutely! We’re currently testing physical cards and plan to launch them soon. They’ll work seamlessly with the Knockin digital experience to create a complete ecosystem. Stay tuned!
Can I see which parts of my profile someone interacted with before following up?
I’m curious about the voice feature. Can users make the responses more casual or professional depending on who is visiting?

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 work
Get answers in your voice
Discover what matters to them
Book time with you directly
Every 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! 🚪
@felix_momen Can Knockin adjust its responses based on the different types of visitors, like clients, recruiters, or potential partners?
Knockin'
@julian_ting2 Not automatically at the moment. Multiple cards are on our roadmap, though, so you’ll be able to create a separate card for clients, recruiters, or partners and define how the AI responds on each one.
@felix_momen the ability to controls what Knockin' can use and set restrictions for its answer is an important details.

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

That’s exactly what we built Knockin for. Thanks for giving it a try!

Congratulations on your launch! There is no counting how many times I've thrown away my business cards when I could not remember where they came from.
For me, as a freelancer, my "business card" is always a Notion page that is never viewed a second time. An AI-driven business card that responds to queries and schedules appointments is the way forward.
