Before you start
Install Lectern (on this site it is a fully activated donation download) and, for the best accuracy, let it fetch an on-device Whisper model once. After that, transcription runs offline. All audio and transcripts stay on your Mac.
Step by step
1. Choose your engine
On-device Whisper on the Neural Engine gives the strongest accuracy; Apple Speech is instant and also local. Either way, nothing is uploaded.
2. Start recording
Begin the session and glance at the live transcript and level meter to confirm clean audio. Capture is interruption-proof, so a notification or app switch will not lose the recording.
3. Let it summarize
At the end, Lectern generates deterministic notes: a TL;DR, a fuller summary, tags, and action items that carry owners and due dates.
4. Review and assign
Confirm the action items, set owners and dates, and export or share the summary with attendees.
5. Search later
Every session joins a full-text searchable archive. Months later you can search a phrase and jump to the exact audio segment where it was said.
Getting clean audio
- Reduce background noise where you can; it helps every transcription engine.
- For remote calls, capture system audio so remote voices are included.
- Speak one at a time; heavy cross-talk is hard for any model.
Frequently asked questions
Can I transcribe a meeting without uploading the audio?
Yes. Lectern runs on-device Whisper or Apple Speech locally, so the audio and transcript stay on your Mac and never reach a server.
Does offline transcription work without internet?
Yes, once the model is installed. On-device Whisper runs fully offline, which is ideal for confidential meetings or poor connectivity.
Can I extract action items automatically?
Yes. Lectern produces action items with owners and due dates as part of its deterministic notes, alongside a TL;DR and summary.
