Show HN: Open a phone number in WhatsApp without saving contact

3 pointsby mayerwinabout 1 year ago
I made a simple HTML app that can help open a phone number in WhatsApp (web on desktop or app on mobile) without having to create a contact first.<p>Source code is available on GitHub. Enjoy and share it with your friends and family (they will thank you if they&#x27;re using WhatsApp)!<p>I used ChatGPT 4 (even for the favicon) but couldn&#x27;t say it was faster than writing it from scratch. It was a completely different kind of debugging and improvement process. What was really missing was a way for ChatGPT to automatically see the results of its code and do a few iterations to benefit from a feedback loop. Even just asking it to read its own reply and fix&#x2F;improve it works wonders, but showing it screenshots is yet another step forward.

Really nice and clean!<p>I made something a little similar - <a href="https:&#x2F;&#x2F;github.com&#x2F;fotoflo&#x2F;alfred-whatsapp-linker">https:&#x2F;&#x2F;github.com&#x2F;fotoflo&#x2F;alfred-whatsapp-linker</a> - this one is an Alfred Workflow (<a href="https:&#x2F;&#x2F;alfredapp" rel="nofollow">https:&#x2F;&#x2F;alfredapp</a>) that assumes you have a phone number in your clipboard and then opens it in whatsapp. I suppose yours is more elegant.<p>How long did it take you + GPT to create it?
