Arca: Private Speech to Text

Arca: Private Speech to Text - No Cloud. No Account. Ever.

Arca is a professional-grade transcription tool that runs entirely on your device. No internet required. No data leaves your phone. Ever.
In a world where every voice app sends your audio to the cloud, Arca does the opposite. Your recordings stay on your hardware, encrypted and protected - whether you're a therapist, lawyer, journalist, or anyone who values privacy.
THE ON-DEVICE GUARANTEE

100% Local Processing: Every word is transcribed on your device using on-device machine learning. Nothing is uploaded. Nothing is shared.
No Audio Uploads: Your recordings are never sent to a server, never stored in the cloud, and never used to train AI models.
