I work on a remote team, and whenever someone had a birthday, a work anniversary or a last day, there was no good way for all of us to sign one card. Someone would share a link to a doc or a board, half the team would miss it, and what the person got at the end never really felt like a card.

So I built the thing I wanted:

1. Describe who the card is for in a sentence, or upload a photo. The AI designs a cover and drafts an opening note, and you can regenerate either until it feels right.

2. Share one link. Everyone signs from their own phone or laptop and can add a GIF. Nobody needs an account or an app to sign.

3. Send it by email or link. It opens as a 3D card they can flip through and come back to any time. It's free, and there's a Slack app, so you can start a card with /cardshareai without leaving Slack.

I'd love to hear what's missing. What would stop you using this for your team's next card, or what would make it a no-brainer? I'll be here all day answering every comment. Thanks!
