AI Note Taker App for Meetings, Calls and Lectures

Phone app that records meetings, calls and lectures, then transcribes and summarises them with AI.

In plain English

Wave is a phone app that records meetings, calls and lectures and turns them into notes. AI writes the transcript and a short summary you can search later. The founder runs it almost alone, using AI tools to build it. Users pay a subscription inside the app.

Realistic income

In a Mixergy interview (Feb 3, 2026), founder Josh Mohrer said Wave AI is at about $7 million in annual recurring revenue, with roughly $3 million kept after costs, and that he runs it essentially solo. This figure is operator-reported, not independently verified, and may be out of date. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.

Risks

  • Recording others may need consent depending on local law.
  • Very crowded note-taker category.
  • App store fees and review rules.
  • Startup cost and time to first dollar are not disclosed.
