Lucy — Private Transcription for Professionals

The privacy label says it all.

Not Linked to You Apple App Privacy — Diagnostics

That is Apple’s privacy nutrition label. Lucy collects exactly one thing: anonymous crash and performance diagnostics, so that bugs get found and fixed. Nothing you record is part of it. Your audio, transcripts, summaries and meeting names never leave your device — there is no server that could receive them.

Audio stays on your device
Transcripts stay on your device
No advertising, no tracking, no profile of you, no account — ever.
Anonymous crash, performance and usage diagnostics are the only thing Lucy sends. They are stripped of file paths, meeting names and transcript text, and never linked to your identity.
Turn on Airplane Mode — Lucy still works. Transcription runs entirely on-device.

Record. Transcribe. Review.

The whole pipeline runs on your device, offline.

1
Record
Tap Record. Lock your screen or switch apps — recording keeps going, and the Dynamic Island shows it.
2
Transcribe
Tap Stop. Whisper, Parakeet or Apple Speech runs an accurate offline pass. Speaker attribution labels up to 4 voices on recordings, and more on imported files.
3
Review & export
Fix speaker labels, jump to any moment, compare versions, generate an on-device summary you review before it is saved. Export to plain text, Markdown, or PDF with speaker labels and timestamps.

Built for professionals who can’t use the cloud.

Mental health practitioners

Document sessions privately. Therapist mode improves transcription of clinical vocabulary. Because Lucy processes everything on-device and we never receive your audio, no BAA is required for Lucy — confirm your practice’s own compliance obligations.

Lock a session and the transcript and audio are encrypted at rest, tied to Face ID or Touch ID. No recovery path — only you can unlock it.

Therapist mode — free vocabulary mode, no extra purchase.

Legal professionals

Record depositions, client meetings, and case discussions. Legal mode improves transcription of legal vocabulary.

Lock a session and the transcript and audio are encrypted at rest, tied to Face ID or Touch ID. No recovery path — only you can unlock it.

Legal mode — free vocabulary mode, no extra purchase.

Anyone who can’t use the cloud

M&A calls, board discussions, sensitive interviews, HR meetings. If the recording can’t leave the room, Lucy is the right tool.

Honest about what works best.

Best results with:

Quiet or low-background-noise environment
2–4 speakers with distinct voices
One language per recording
Phone within 3 feet of speakers

Transcripts may require correction for heavy accents, technical vocabulary, and overlapping speech. Review flagged lines and speaker labels before exporting.
