unWarp is a hosted service that turns voice memos and calls into searchable notes with a summary and action items; it runs in the browser, and calls are recorded by its Windows and macOS desktop app. Personal is €10/month, teams €8/seat, 14-day trial. Note before using it: nothing joins the call as a visible participant, so other people are not notified of the recording, and consent law, employer policy and platform terms still apply.
