Hujam.
Words you
can actually
own.
Hujam records, transcribes, translates and writes reports — entirely on your device. No cloud mandated. No leaks. The models live on the phone. The audio never leaves it unless you need it. Encrypted data at rest.
Yours.

A local LLM turns the transcript into the document you actually needed — interview brief, court note, field summary, captions.
All voice
workflows need!
Nothing more.
On-device by design
Audio, transcript, translation and report never have to go to the server. You decide when and how to export
