Most recorders give you hours of audio and no way back to what mattered. AI Lecture Recorder lets you tap a live bookmark the moment something important is said, then jump straight to it later. Recordings stay on your iPhone (local-first, no data collected), with background recording, pause/resume, trimming, and speed playback. AI transcription is optional, so you only use it when you need searchable text. Export audio along with notes, bookmarks, and transcripts.
