WHY SONORIX

Transcription is the start of the workflow, not the end.

A fast voice-note-to-workflow path for mobile recordings, personal notes and conversations.

Phone-friendly

Upload common M4A voice recordings without an extra format conversion step.

From note to action

Extract next steps and commitments instead of leaving ideas trapped inside audio.

Search and export

Keep the transcript searchable and export it when you need a document or caption file.

HOW IT WORKS

Simple on the surface. Sophisticated underneath.

The user sees one focused flow: upload → transcript → useful output. Behind it, Sonorix uses durable jobs, provider fallback, resource guards, grounded intelligence, privacy cleanup and automatic recovery without exposing that complexity to the user.
