MementoBook - Turn any event into a keepsake everyone helped create

Hey Product Hunt! 👋 I'm Fernando, co-founder of Entrinsia and the maker behind MementoBook. The idea came from a frustration I kept seeing at events — the guest book sitting in the corner with nobody near it, disposable cameras coming back with 40 blurry photos of the ceiling, and guests who meant to sign the book but never made it back. And then there's the bigger problem nobody was solving — the friend who moved abroad, the grandparent who couldn't travel, the family member on the other side of the world. They couldn't be there, but they had something to say. So I built MementoBook. Set up a tablet kiosk at your venue, or invite guests to contribute from their own phones from anywhere in the world. Video messages, photos, voice notes, handwritten notes — we compile everything automatically into one beautiful keepsake video your guests can all share privately. It works for weddings, birthdays, graduations, group travel, family reunions, sports teams, school trips and more. Your first event is completely free. No subscription. Ever. I'd love to hear your feedback and answer any questions — this community has been a huge inspiration in getting MementoBook to launch day. 🙏
