Curious thoughts arrive when you can’t stop to look them up. They get forgotten, scattered across notes or lost in open tabs.
Hypothesis
If saving a thought takes seconds and old ones come back gently, people will return to their curiosity instead of losing it, and act on the ones that matter.
How it works
Calm by design: no points, streaks or red counts
01Catch itSave a Curiosity (an idea) or a Wondering (a question) in seconds. No account needed.
02Meet it againOnce a day at most, an old thought you haven’t opened comes back as a quiet Still curious? card.
03Act on itBreak it into next steps and send them to Nudge!, where they become tasks.
Curiosities and WonderingsIdeas and questions get their own homes, so neither gets lost in the other.

Open questions
How much should an AI answer say, and how should it show its sources?
Is one resurfaced thought a day the right amount?
Do people need tags or pins beyond categories and search?
