Hi Product Hunt! I built Cardlake because useful things kept getting lost in my AI chats: a link Claude found, a follow-up I agreed in ChatGPT, an idea I meant to come back to. They were all in a chat somewhere, never in one place I actually check.
Cardlake is one feed for reminders, learnings, bookmarks, work and ideas, and you can go through it in a few minutes. Connect Claude or ChatGPT and you can save to it just by asking, then find it again from a different chat days later, because both assistants use the same Cardlake account.
Two things it deliberately isn't:
A background memory. Nothing is saved unless you or your assistant save it on purpose, and it never reads your chat history.
A lock-in. There's an open-source edition (AGPL-3.0) you can run on your own Vercel and Neon accounts.
The personal app is free to start with Google sign-in. I'd love to hear what you'd save first, and what would make the feed worth coming back to.
