Can I transcribe research interviews offline on a Mac?
Yes. Lesskeys transcribes interviews and focus-group recordings on-device using Apple Silicon's GPU, so nothing is uploaded and it works without an internet connection. For studies where participant confidentiality and data-handling rules matter, keeping recordings on your own machine keeps the data contained.
Speaker separation for focus groups
Multi-participant recordings are hard to code when you can't tell who said what. Lesskeys applies automatic on-device speaker diarization — labeling each participant, with persistent voiceprints so a recurring participant can be recognized across sessions — so your transcripts are ready to analyze.
Useful for study workflows
- 99 languages with auto-detect for multilingual fieldwork.
- Transcript-synced player to re-listen to any coded segment.
- Import your existing audio/video files, or capture new recordings locally.
- No per-minute cloud fees — a one-time purchase.
A working setup for a study
- Collect — import session recordings from your recorder or capture remote interviews locally on your Mac.
- Transcribe on-device — every session is transcribed and diarized locally, which keeps participant data inside your own data-handling boundary.
- Label participants — assign codes or names per speaker; recurring participants can be recognized across sessions.
- Code and cite — use the transcript-synced player to re-listen to any segment, then export TXT into your analysis tool.

FAQ
Can I transcribe research interviews offline on a Mac?
Yes. Lesskeys transcribes qualitative interviews and focus groups entirely on your Mac, offline, so participant audio is never uploaded.
Does it separate multiple participants?
Yes. Automatic on-device speaker diarization labels each participant — useful for focus groups and multi-person interviews.
Is it suitable for participant confidentiality?
Recordings and transcripts stay on your device with no cloud upload, which helps keep participant data contained. Follow your institution's own data-handling and ethics requirements.
