Why we build local

Cloud AI is the wrong tool for serious work

🛡️

Privacy isn't a feature

Doctors, lawyers, journalists, therapists, support staff — their conversations cannot ride a cloud STT service's training pipeline. Local is the only honest answer.

🎯

Generic accuracy is a ceiling

Cloud STT is averaged across millions of voices. It will never get YOUR accent, jargon, or proper nouns right. Voice profile training breaks that ceiling on your machine.

💰

Subscriptions are surveillance

A subscription that streams your voice to someone else's servers, forever, is a worse deal than a tool you pay for once and run locally for the next ten years.
