That headspace is not always there. A good example is when I sit down to watch something on a streaming service and end up browsing for ages instead of committing to anything. In theory, that would be a perfect moment to actively review things I have saved, but in practice I am not convinced my neurodiverse brain would reliably cooperate.
So to your question, I think I would lean much more toward a context-based mode than a time-based one. A fixed daily slot would quickly turn into another obligation. A lightweight “I am in curiosity mode right now” switch feels closer to how my brain actually works, especially if the radio-style playback keeps the cost of re-entry low.
If I were to design around your constraints, it would look like:
* a manual toggle for “curiosity mode”
* a queue that plays 1–3 small “snack” insights (not full summaries)
* and a single “save this to revisit” action that you can do in 1 second, so you don’t lose it while driving
One question: when you hear something interesting in that mode, what’s the most natural next step for you later—open the original link/video, add it to an “active project/topic”, or capture a single note like “try X / look up Y”? (More context on the direction I’m validating is in my HN profile/bio if you want to compare.)
