How it works

1

Record on iPhone

One tap to start. Records in the background — lock your phone, switch apps, put it in your pocket. Voice-optimised 16kHz or high-fidelity 48kHz.

2

Auto-sync to Mac

Pair once with a 6-digit code. Recordings sync over your local Wi-Fi — never through the cloud. Authenticated and encrypted end-to-end.

3

AI processes locally

Your Mac transcribes (whisper.cpp), identifies speakers, generates summaries, action items, and mind maps — all on-device using local AI models. Nothing leaves your machine.

Features

Transcription

Speech-to-text with timestamps powered by whisper.cpp. Runs entirely on your Mac's CPU/GPU.

Speaker identification

Automatically labels who said what. Name a speaker once and they're recognised in future recordings.

AI summaries

Meeting minutes, action items, key points, SOAP notes, Cornell notes — generated locally by llama.cpp.

Mind maps

Structured outlines generated from your transcripts. Export as Mermaid or OPML.

PLAUD Note support

Already own a PLAUD Note? OpenPlaudit syncs recordings directly over Bluetooth — no PLAUD cloud required.

Background recording

iPhone records while locked or in another app. Live Activity shows elapsed time on your Lock Screen.

Private by design

OpenPlaudit was built for people who can't afford to have their conversations in someone else's cloud. Lawyers, therapists, journalists, executives — your recordings stay on your devices.

No cloud processing No accounts No analytics No ads
