Can I use Cardlake without an AI assistant?

Yes. You can sign in with Google and add and review cards directly in the web app. Connecting an AI assistant is optional, and you can also try the sample feed without signing in, though demo changes are not saved.

Can I save in one AI assistant and retrieve from another?

Yes, when both assistants are connected to the same Cardlake account. You can ask one connected assistant to save a note or reminder, then ask another to retrieve it from Cardlake, sharing the saved items but not the assistants' full conversation histories.

Does Cardlake automatically read all my AI chats?

No. An assistant connection lets you ask that assistant to read and manage your Cardlake cards, but it does not give Cardlake automatic access to your past chats. You save the useful information you want to keep, or configure a supported source such as GitHub Issues.

Is Cardlake free, and how do I start?

The personal web app is currently free and uses Google sign-in. You must be 18 or older. If account capacity is reached, new users join an access waitlist. Your AI provider may have separate plan or connector requirements.

How is Cardlake different from saving a bookmark?

A bookmark keeps a link, while Cardlake puts bookmarks alongside reminders, learnings and work follow-ups in a daily review feed where you can snooze, pin or mark cards as favorites to help revisit them.

Overview

Screenshot of the Cardlake homepage — What cardlake.app looks like

Cardlake is a personal knowledge and reminder app that centralizes notes, learnings, bookmarks and work follow-ups from multiple AI assistants and sources into one daily feed. Save items directly in the web app, ask connected AI assistants like Claude or ChatGPT to save them, or integrate with sources like GitHub Issues. The app lets you review, snooze, pin and favorite cards, with a daily review habit that rewards showing up rather than reaching inbox zero. You can access saved items from any connected AI assistant or the web app.
