FAQ
Does it work with free Claude accounts?+
Yes. Claude Calendar works with any Claude account — free or Pro. It tracks conversations regardless of your subscription.
Can it read my conversation messages?+
No. The extension only captures the title, URL, and timestamps of your conversations — never the content. Your messages stay completely private.
Will it slow down Claude?+
No. The extension runs passively in the background. It notices when a conversation page loads and records the title and timestamp — nothing more.
Will it show conversations I had before installing?+
Yes. Claude Calendar fetches your full conversation history automatically — titles and dates going back as far as your account has been active. Everything is there from day one.
