Using tools like Claude Code, Cursor, and modern AI APIs and MCPs, I went from idea to a working mobile app that can record voice notes, transcribe them, organize them, and even extract tasks. After going through this video, you can build your own AI apps including voice transcription features, authentication, paywalls and so much more!
