Secure Offline Transcription, with Full Data Ownership

Runs offline
On-device
Android

Every transcription service asks you to send the recording somewhere. Rhetoria transcribes everything directly on your phone. The audio never leaves the device, and all of your transcripts are stored in an ecrypted partition on your device.

The whole workflow runs on one machine. No upload step, no processing queue, no vendor copy.

Transcription runs on your own hardware. No network connection is required to work.
No Copy
The recording is never transmitted, so no third party ever holds a copy of it.
Encrypted
Speed claim. Real-time factor, or minutes of audio per minute of processing.
Export
Export formats. TXT, SRT, VTT, DOCX, or whatever Rhetoria actually writes out.
The friction

The recordings that most need transcribing are the ones you are not allowed to send.

Transcription stopped being a hard problem years ago, as long as you are willing to hand the audio to somebody else. That willingness is exactly what a privileged conversation, a patient interview, a source protection agreement, or an active investigation removes. So the work goes back to a person with headphones and a keyboard, at a cost nobody budgets for and a turnaround nobody likes.

The workarounds are worse than the problem. Teams strip identifying details before uploading, which corrupts the record. They transcribe only the parts they think are safe, which biases what gets analyzed. Or they route around policy quietly, which is how a compliance finding starts.

None of this is a transcription problem. It is a custody problem.

Custody breaks on upload

The moment audio reaches a third party, the chain of custody has a gap you cannot close afterward.

Manual transcription does not scale

Typing it by hand protects the material and quietly caps how much of it anyone can afford to review.

Redaction corrupts the record

Stripping detail to make audio safe to send changes the thing you were trying to analyze.

How it works

Install it, record, transform it.

Rhetoria is a tool, not a deployment. There is no environment to configure and no integration to schedule before it does the thing you downloaded it for.

Capture

Your offline thought and idea capture agent.

Rhetoria has a live microphone capture, that works in Airplane mode. Use it to capture draft chapters of your latest novel, draft an email, or record an in person meeting at a coffee shop. (Be sure to get consent first)

The recording stays where it was made.

You already knew what you wanted transcribed. What you did not have was a way to do it without handing the audio to somebody who should not have it. Rhetoria removes that step entirely, and everything downstream of it.
