nope , that nprofile is using justplain Nostr DMs (nip-04), not OpenMLS.

OpenMLS is the rust lib that Vector uses to build *its* encrypted group chats; it’s MLS, the new IETF standard (tree-based e2ee). You and a bunch of pals share keys, adapt as folks join/leave, and it still stays broken for outsiders.

Whisper is the openai tiny-speech model we bundle locally in Vector. hit record → audio never leaves your phone → local transcriber spits out the text, then we encrypt the voice note + text and gift-wrap it off to your mate. no google, no apple, no cloud ears.
