Thanks — this is extremely helpful, especially the constraints: you want semantic search + “where/when to execute”, calendar as a key context source, and migration cost as a hard friction point.

YAML/JSON as a local knowledge store is a nice wedge too: it keeps things portable and makes “AI suggestions” easier to reason about.

Re the waitlist: the landing page is up now (https://concerns.vercel.app), and you can leave an email there. I’ll make sure you get an update when there’s something testable.

One quick follow-up: if you could get only one capability first, would you pick

a) semantic recall (find related knowledge without exact keywords), or

b) a daily “top 3” plan generated from calendar + your knowledge store (pulled on demand, no interruptions)?

Details are in my HN profile/bio if you want more context.
