Stardust Recorder
On-device voice transcription
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Now in 99+ languages with auto-detect. Your voice transcribed on-device with Whisper. Apple Intelligence summaries. Private by design.
Stardust Recorder is a private voice transcription app that runs entirely on your iPhone. Your recordings, transcripts, and summaries never leave your device. No accounts. No servers. Just you and your voice.
WHY STARDUST
We built Stardust because voice transcription apps shouldn't require sending your audio to someone else's servers. Your conversations, your interviews, your private thoughts — these belong to you.
Stardust uses on-device machine learning to transcribe in 99+ languages, generate summaries with Apple Intelligence, and extract action items from any recording. Everything happens on your phone's processor. Nothing is uploaded.
