Smart Repeater

Repeat YouTube sentences with instant translation, synchronized speech, and precise controls for focused language learning.

Turn YouTube captions into focused language practice — one sentence at a time. YouTube Smart Repeater helps you listen more carefully, catch difficult words, improve pronunciation, and review without constantly reaching for the video controls. It divides captions into clear sentence-sized segments, repeats the current sentence as many times as you choose, keeps the original text visible, and can translate and read the sentence aloud. WHY LEARNERS USE IT • Repeat each sentence automatically with an adjustable repeat count. • Move instantly to the previous or next sentence. • Translate captions into multiple languages while keeping the source visible. • Hear synchronized speech with voice and speed controls. • Control practice with clear keyboard shortcuts. • Reduce distraction with focus, blackout, and interface-hiding modes. • Keep controls available in a separate floating window with the Cloud plan. • Get started through a simple English and Arabic onboarding flow. BUILT FOR DELIBERATE PRACTICE Instead of replaying an entire video or dragging the timeline, you stay with the exact sentence you want to understand. Listen, imitate, repeat, and move on when you are ready. HOW IT WORKS 1. Open a YouTube video that has captions. 2. Start YouTube Smart Repeater. 3. Choose the repeat count and translation language. 4. Practice sentence by sentence using the on-screen controls or keyboard. PRIVACY AND OPTIONAL SERVICES The extension works on YouTube pages and does not sell personal data or collect general browsing history. Translation, speech, licensing, or optional AI features may connect only to the services selected or required for those features. Optional Gemini, Groq, Anthropic, and Fish Audio features require a key supplied by the user; those keys are stored locally in extension storage. A 3-day free trial is included. Continued access after the trial requires a subscription. Core practice during the trial does not require an AI API key.
