Keepsake: Turn iMessage chats into a formatted, print-ready PDF

Hey, I'm Julian, built this myself with a lot of help from AI along the way. Basically I wanted to save an old conversation with someone I care about and realized there's no real way to do it on iPhone, no export button or anything like that. The free options are things like printing from a Mac, which cuts off long conversations, and the paid options are $30-50 desktop apps built for general phone backups, not really for making something you'd actually want to keep. Started out just wanting a simple export, ended up caring a lot more about privacy once I got into it. Everything runs in your browser now, nothing gets uploaded anywhere, which felt important given it's someone's actual private conversation. It reads your chat.db, an iPhone backup, or even just pasted text, and turns it into a proper PDF with the real chat bubbles, photos, dates, all of it. First time building something like this, would love any feedback.
