Offline Voice & Speech to Text

Transcribe audio to text offline, with no internet connection and no account. Your recordings never leave your phone.

Speech to Text Offline turns voice recordings, meetings, lectures, interviews and voice memos into text using on-device AI. It works in airplane mode, on a plane, underground, or anywhere with no signal. Nothing is uploaded, nothing is stored on a server, and you never sign in.

ANY LENGTH

Transcribe recordings of any length — short voice memos or multi-hour meetings, lectures and interviews. Audio is read and processed in segments, so a long recording is transcribed end to end on an ordinary phone, with text appearing as it goes.

WHY OFFLINE MATTERS

- Works with no internet, no mobile data and no Wi-Fi

- No account, no sign-up, no subscription

- Your audio and transcripts stay on your device

- Suitable when recordings are confidential and cannot be sent to a cloud service

LIVE RECORDING

Record audio directly in the app with one tap. No need to use another app first — just hit Record, speak, and transcribe instantly.

SLIM INSTALL + OPTIONAL AI TOOLS

The app installs at about 250 MB and transcribes out of the box in 99 languages. AI Tools (summarize, translate, sentiment analysis) are an optional one-time download (~3.5 GB) you start whenever you want from Settings — and you can free that space anytime from Settings → "AI Tools storage".

AI-POWERED TOOLS (OPTIONAL DOWNLOAD)

Once you download the AI Tools pack, you can:

- Summarize transcripts into key points

- Analyze sentiment (positive, negative, neutral)

- Translate to 15 languages: English, French, Spanish, German, Italian, Chinese, Japanese, Arabic, Portuguese, Korean, Russian, Hindi, Slovenian, and more

All AI processing happens on-device. Your conversations stay yours.
