AllSpeak Captions

Offline, projector-ready live captions. Pick your platform below.

Runs fully offline

Transcription happens entirely on your machine. No audio or captions ever leave it, or the local network in present mode.

Boosts your vocabulary

Boost the terms your material actually uses (names, jargon, subject-specific words) so the decoder prefers them live. No retraining.

Broadcasts to the room

Present mode serves captions to any phone on the same Wi-Fi. No app to install, no internet required, view-only for the audience.

Clean transcripts

Filler words are stripped and flagged words are masked automatically, word-boundary aware, so the caption stream stays readable.
