Ask HN: Do you also "hoard" notes/links but struggle to turn them into actions?

Summary

Hi HN — I’m exploring an idea and would love your feedback.I’m a builder and user of Obsidian, validating a concept called Concerns. Today it’s only a landing page + short survey (no product yet) to test whether this pain is real.The core idea (2–3 bullets):- Many of us capture tons of useful info (notes/links/docs), but it rarely becomes shipped work.- Instead of better “organization” (tags/folders), I’m exploring an “action engine” that: 1.detects what you’re actively targetting/working on (“active projects”) 2.surfaces relevant saved material at the right moment 3.proposes a concrete next action (ideally pushed into your existing task tool) My own “second brain” became a graveyard of good intentions: the organizing tax was higher than the value I got back. I’m trying to validate whether the real bottleneck is execution, not capture.Before writing code, I’m trying to pin down two things:- Project context signals (repo/PRs? issues? tasks? calendar? a “project doc”?)- How to close the loop: ingest knowledge → rank against active projects → emit a small set of next-actions into an existing todo tool → learn from outcomes (done/ignored/edited) and optionally write back the minimal state. The open question: what’s the cleanest feedback signal without creating noise or privacy risk? (explicit ratings vs completion events vs doc-based write-back)What I’m asking from you:1.Where does your “second brain” break down the most?capture / organization / retrieval / execution (If you can, share a concrete recent example.)2.What best represents “active project context” for you today? task project (Todoist/Things/Reminders) issues/boards (GitHub/Linear/Jira) a doc/wiki page (Notion/Docs) calendar "in my head" Which one would you actually allow a tool to read?3.What’s your hard “no” for an AI that suggests actions from your notes/links?
