Show HN: TapFi – Point your camera at handwritten WiFi credentials to connect (opens in new tab)

I've submitted this before but it got lost in the noise so hope it's ok to submit it again, I've added quite a few new features since last time

This is a little app I built to deal with a pain point I find when travelling a lot, often you're in a cafe/pub or airbnb and the wifi details will be written down on a card or on a poster, this simply lets you take a picture of the details and it works out the SSID/Password (using Claude Sonnet) and connects you

New features since the last post:

- Create and share a QR code with others, so they can just scan the QR code and connect

- Use a photo from your library

- Save wifi details to connect later

Open to all feedback/criticism/improvement suggestions

Cheers :)
