On-device transcription

On-device meeting transcription. Your audio never leaves your device.

On-device meeting transcription means the speech-to-text runs entirely on your device, with no audio sent to a server. mind² ECHO transcribes meetings locally with the Whisper speech model and tells speakers apart on the device, so a recording of a private conversation never has to travel to anyone’s cloud.

What on-device transcription means

Most meeting tools upload your audio to their servers to transcribe it. On-device transcription does the opposite: the model that turns speech into text lives in the app and runs on your device’s own processor. The audio is read and transcribed right there, and it stays on the device, kept locally so you can replay it, share it, or re-transcribe it later. Nothing about the recording, not the audio and not even the raw transcript, has to leave the device for the words to appear.

How mind² ECHO transcribes locally

Transcription uses the Apache-licensed ACFT Whisper models from FUTO, whose mission is freeing technology from the control of the few. Speakers are then told apart by the open-source sherpa-onnx stack, a pyannote segmentation model paired with wespeaker speaker embeddings. All of it runs offline on the device, in real time, so you watch the transcript build as people speak.

Why local transcription matters for privacy

A meeting is one of the most sensitive things you can record: salaries, strategy, health, personal conflict. Keeping transcription on-device means that sensitive audio is never exposed to a third-party server, a subprocessor, or a data breach you would never hear about. When you ask the room to agree to a recording, you can honestly say the audio stays on your device. Only the transcript text, never the audio, is later sent for AI analysis, and only with your explicit consent; the server does not keep it.

Works for in-person meetings, no bot required

Because mind² ECHO records through your device’s microphone, it works around a table just as well as on a video call. There is no meeting bot to invite into the call and nothing for the other participants to install. One tap starts the recording; the transcript and the per-speaker analysis follow.
