I built an offline networking QR app with AI — launched today
The problem: online, sharing a link takes one click; offline it falls apart — contacts, products, projects, all stuck behind “I'll send it later.” The fix: one mobile page, every link as a QR code with one-tap copy. Built-in local editor — data never leaves your device. Installs like a real app on iOS & Android from the browser, works offline, open source.
The experiment: all code written with AI assistance (Claude), all product decisions mine. Full commit history is public if you want to see how a non-dev ships.

Honest feedback welcome — especially on what would make you actually use it at your next event.
The “I’ll send it later” problem is a good one to build around, and keeping the data on-device is a surprisingly important detail for something people might use at events.
Since you launched today, this feels like it could be pulling a lot more organic traffic than it probably is right now once people start looking for simple offline ways to share links and contacts.
I’m curious which type of event you built this around first?
Thank you, Muhammad — you picked up on exactly the two things I cared about most. The on-device part wasn't even a "feature decision" at first: I simply didn't want to build a backend for a side project. Then I realized it is the feature — at an event, the last thing you want is another service holding your contacts.
It started with professional conferences — that's where I felt the pain the most: someone asks for your LinkedIn and the moment dies while you're searching for your own profile. But the surprise came from casual settings — meetups, dinners, chance conversations — where people often aren't on LinkedIn at all. That's what shaped the "where are you?" flow: you just show Instagram or TikTok or a plain phone number instead.
Fair point on organic traffic — "how to share links offline" is a real search behavior and I haven't done anything for it yet. Post-launch homework 🙂
Curious back: what kind of events do you end up exchanging contacts at most?
Your reply actually confirms the SEO opportunity I was thinking about — “how to share links offline” is exactly the kind of problem-driven search where people are already looking for a solution.
Now that you’ve also discovered the meetup/dinner use case beyond conferences, I’d consider building the organic strategy around these specific situations rather than only positioning it as a networking app.
There’s a lot of room to build search visibility around offline link sharing, QR networking, sharing contacts at events, and similar use cases. I can help with the organic traffic + authority side here and already have some ideas for Smart Networking.

The interesting part is not really the QR code—it’s whether removing the “I’ll send it later” friction changes what people actually do at events. I’d be curious which use case you think has the strongest pull: sharing contact details, projects, or something else.
Great framing, Aryan — agreed, the QR is just the delivery mechanism. The real bet is behavioral: whether removing that 30 seconds of friction changes what happens after the conversation.
From my own use so far, the strongest pull is contact details — LinkedIn or a phone number — simply because it's the highest-frequency moment: it happens in almost every new conversation. That's the "hygiene" use case.
But the more interesting one is projects. Sharing your LinkedIn is expected; showing your book, your podcast, or a side project in the moment is where behavior actually changes. Before, "I'll send you the link" meant the project never got seen. Now it gets opened while you're still talking — and the reaction happens face to face. That's a different quality of moment entirely.
So: contacts drive frequency, projects drive the "wow, this changed something" feeling. If I had to bet on what makes people keep the app, it's the second one.
What would it be for you — do you find yourself failing to share contacts more, or your own work?
That distinction between frequency and impact is interesting. For me, it’d probably be projects — those are much easier to say “I’ll send you later” and then never actually send. I’d be interested in continuing the conversation; what’s the best email to reach you at?
Glad it resonated, Aryan — and you just made my point for me: projects are exactly the "I'll send it later" victims 🙂
Happy to continue the conversation! Easiest way: all my contacts are in the app itself — pick whichever channel works for you.
Thanks! I’ve just sent it over.
Looking forward to hearing your thoughts whenever you have a chance.
