About this app

Caption Flow brings live caption and live translate to everything you watch or listen to. Get real-time text for conversations, videos, and apps, with flexible overlays designed for accessibility and language learning.

Why you’ll love it:
• Live Caption + Translation: Turn spoken audio (internal or microphone) into readable text instantly.

• Live Translate: Continuous live translation of text in a specific area of the screen you select (for example, you want to translate existing subtitles).

• Instant Screen Translate: One-time screen translation of anything you're viewing without opening the app. This feature uses Android's AccessibilityService API to access the text displayed on your screen when you trigger a translation, so that Caption Flow can translate it for you.

• Subtitle Overlay: Play SRT files in a draggable overlay with playback controls that stays on top of any app.

• Language learning tools: Instantly translate words in overlays with a double tap, save new words, and build confidence.

• Privacy-focused options: Use offline modes to keep audio on your device, or go online when you want the broadest language coverage and best accuracy.

• Accessibility-focused: Clearer understanding for deaf and hard-of-hearing users, and for anyone in noisy environments.

• All features support offline usage, which is fully free. If you'd like to experience the best quality & fastest speech-to-text and translations, try premium for 7 days free!

Make every conversation and piece of content easier to follow with Caption Flow.
