Sentence Listening Console

Improve listening in any language on Bilibili and YouTube with sentence marking, navigation, looping, and local progress.

Sentence Listening Console helps you practice focused listening with Bilibili and YouTube videos in English, Japanese, German, Chinese, and other languages. Instead of relying on platform subtitle APIs, you can mark sentence boundaries directly while a video is playing. The extension then turns those timestamps into reusable sentence controls. Main features: - Mark sentence boundaries directly from the video - Jump to the previous, next, or any selected sentence - Loop one sentence continuously - Play every sentence a selected number of times - Pause between sentences for focused recall or dictation - Loop a selected range of sentences - Add optional color markers to sentences - Save point data and learning statistics locally - View listening history and per-video statistics - Import and export point data as JSON - Use W, S, A, and Space keyboard controls after marking The extension supports Bilibili and YouTube. It does not require subtitles and can be used for listening practice in any language. Point data, interface preferences, and learning statistics are stored locally in Chrome. The current version has no account system, cloud synchronization, advertising, or developer-operated analytics service.
