Speech to Text - Offline AI

Turn any audio into text — entirely on your device. No internet required, no data ever leaves your phone.

Speech to Text Offline uses on-device AI to transcribe voice memos, podcast clips, and meeting recordings shared from any app. You can also record directly from your microphone. Get an accurate transcript in seconds.

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 18 languages: English, French, Spanish, German, Italian, Chinese, Japanese, Arabic, Portuguese, Korean, Russian, Hindi, Slovenian, and more

- Auto-detect the language of your audio

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