How to Capture Ideas on iPhone So You Can Find Them Later

Ideas show up as a voice note on a walk, a screenshot, a saved reel or a link sent to yourself. Here is how to keep them in one place where you can find them again.

By Ilian Raykov, founder of BrainTube

The short answer

  • Send voice notes, screenshots and links to BrainTube from the share sheet.
  • Each idea is transcribed or read, summarised and linked to related saves.
  • Search by meaning and let recall resurface ideas worth revisiting.

Step by step

1. Capture in the moment

Record a voice memo, take a screenshot or copy a link, the way you already do.

2. Share it to BrainTube

Tap Share and choose BrainTube. Voice notes are transcribed and screenshots are read, so the idea becomes text.

3. See connections

Related saves are linked automatically, so an idea from today sits next to the one from last month.

4. Bring ideas back

Search by what you meant, ask Cue to pull related ideas together, and let recall resurface the ones worth revisiting.
