Use your iPhone as a wireless mic for LLT Desktop and dictate straight into any app on your Mac — or start a translation on the Mac, all from your phone. Or dictate on the iPhone and save the result as a note (original, translation, or both). A reliable, cable-free alternative to Continuity. LOCAL MODE — GDPR-COMPLIANT LLT Backend runs on your own Mac (Apple Silicon, or any machine with an NVIDIA GPU). Audio goes from your iPhone over local Wi-Fi and is processed entirely on your hardware — Whisper for transcription, Mistral for translation. Nothing leaves your network. Ideal for schools, hospitals, law firms, government, and broadcasters with strict data protection needs. 5 SPEECH ENGINES • LLT Backend — your own Mac, local Whisper + Mistral, no cloud • OpenAI Whisper — highest transcription quality • Deepgram — fastest real-time streaming • Google Cloud Speech — 125+ languages, built-in translation • Azure Speech — enterprise-grade, built-in translation, low latency VMIX INTEGRATION Send translated captions directly to your vMix title inputs — real-time subtitles on screen without touching your main production computer. Your iPhone becomes the translation appliance. TRANSCRIPTS & SUBTITLES Every session is saved as timestamped TXT and SRT files on your device — and, with iCloud on, in iCloud Drive so they appear on your Mac instantly. Read them in the built-in viewer, or import into YouTube, Final Cut, Premiere, or DaVinci. Share via AirDrop, Mail, or any iOS target. PRIVACY LLT Backend mode keeps everything on your local network. With a cloud engine, you use your own API key and audio goes directly to that provider, never through Adelvo Software. Optional iCloud sync stores files in your own iCloud only. No analytics, no tracking, no telemetry. LLT MOBILE PRO LLT Backend is always free. Unlock all four cloud engines with a one-time purchase. No subscription. SYSTEM REQUIREMENTS • iOS 17.0 or later — iPhone, iPad • Wi-Fi; a Mac with LLT Backend (free) for local mode and the Mac mic/dictation features, or your own cloud API key for cloud engines Developed by Adelvo Software. Part of the LLT family alongside LLT Desktop for Mac and ATB for broadcast.

What's new in this version • iPhone as a wireless microphone for our companion macOS app (LLT Desktop): the iPhone streams audio over Wi-Fi and can remote-start the Mac in "Translate" or "Dictate" mode. • Dictation mode: spoken text is either typed into the focused app on the Mac (via the companion app) or saved on the iPhone as a note (original, translation, or both). • iCloud sync: transcripts and dictation notes can be stored in iCloud Drive ("LLT Mobile" folder) so they appear on the user's Mac automatically. • Built-in viewer for TXT/SRT files (tap to read; multi-select to share/delete).
