Video Subtitles

Learn Hebrew from videos with highlighted subtitles

Watch YouTube, Netflix and StreamIsrael with Hebrew subtitles that show which words you know, track your comprehension, and detect i+1 sentences.

Overview

The subtitle browser transforms Hebrew video content into an interactive learning experience. Subtitles appear with word and sentence level highlighting based on your Anki progress, and you can navigate between subtitles using keyboard shortcuts.

Word Highlighting

Every Hebrew word in subtitles is color-coded: green (mature), orange (learning), purple (potentially known), red (unknown)

Comprehension Stats

Real-time percentage showing how much of the video's vocabulary you know

i+1 Detection

Automatically highlights subtitle sentences with exactly one unknown word

Keyboard Navigation

Jump between subtitles with arrow keys: ← previous, → next, ↓ repeat

Multi-Subtitle Cards

Shift+Click to select a range of consecutive subtitles and create a single card with combined text and audio

AI Translation

Translate all subtitles to English with one click using Claude AI. Translations appear in the sidebar and as a blurred overlay beneath each Hebrew subtitle — click the overlay or press E to reveal. Cached per episode for 7 days so you never pay twice.

    Create Anki Cards from Subtitles

    Single subtitle: Shift+Click any subtitle to open the card creator with that sentence and its audio pre-filled.

    Multiple subtitles: Shift+Click a subtitle to set it as the starting point (it highlights with an amber border), then Shift+Click another subtitle to combine the range into a single card — the text and audio will span all selected subtitles.

    • Shift+Click the same subtitle twice to cancel the selection and create a single-subtitle card instead
    • Regular click while a selection is active cancels it
