Idea

An on-device AI tool that indexes and makes searchable your digital life — screenshots, notes, files, bookmarks, saved posts. Uses vision LLM to process everything locally on your phone overnight, keeping everything private without cloud uploads.

Why this is interesting

Apple's Rewind and now Microsoft's Recall have validated consumer appetite for "searchable life" tooling, and the backlash against Recall's cloud-adjacent approach has created a real opening for a credibly private, on-device alternative. The closest incumbent is Rewind.ai, which pivoted to Mac/PC and raised venture money, leaving mobile largely unserved. The $10k–$50k/mo revenue band is plausible only if the app commands a meaningful subscription ($8–15/mo) and retains users past the initial novelty — both hard to prove in productivity, where churn after 30 days is brutal. The single biggest risk is that on-device vision LLM inference is still too slow and battery-intensive on most phones to run reliably overnight without users noticing and disabling it, making the core promise feel broken before trust is established.
