EdSubs Believes

Subtitles can be the next powerful tool in language learning.

Traditionally, subtitles are used for increasing accessibility and understanding non-native content. With the rise of global streaming, that's changed. Viewers everywhere are watching content in languages they don't speak, on platforms that cross every border. Subtitles are now used more than ever, and with the right design they can become a powerful supplement to formal language learning, giving learners personalized input that reinforces what they're studying in the classroom or with an instructor.

Standard Subtitles only in the audience's language

You are now miracles, breaking chrysalises

The viewer understands the translation but learns nothing of the source language. Spanish is invisible.

EdSubs Multi-language, color-coded, word-aligned

Ya son milagros, rompiendo crisálidas

Already; are; miracles; breaking; chrysalises

You are now miracles, breaking chrysalises

Every Spanish word is visible, color-coded, and mapped word-for-word to English. The viewer learns while watching.

Our Approach

Grounded in Science

EdSubs is aligned with established linguistic research, applied to content you actually want to watch.

Source Language

The original language of the content, color-coded word by word so you can track each term across all four lines at once.

Transliteration

Phonetic romanization for non-Latin scripts (Korean, Japanese, Chinese, Arabic and more), color-matched to the source line so pronunciation and meaning connect naturally.

Word-for-Word Translation

A literal word-by-word translation that shows you how the sentence is built. Color-aligned to the source and transliteration lines above.

Colloquial Translation

A natural translation in your target language, the way a fluent speaker would actually say it rather than a word-for-word rendering.

Grounded in Krashen's Comprehensible Input Theory & Leipzig Glossing Methodology

Stephen Krashen's i+1 hypothesis holds that you acquire language when the comprehensible input you're exposed to is just a step beyond what you already know. EdSubs aligns closely with that thinking, not only by making more content comprehensible, but by ensuring each level removes one layer of support, keeping the learner in that productive zone as they improve. The four-line format draws from interlinear glossing, a technique linguists have used for centuries to align source text with translation line by line. The Max Planck Institute and Leipzig University codified the rules. We adapted them for video.

Five Levels of Scaffolding

Start with full support and remove scaffolding as you improve. The source language is always present because research shows it is essential for true acquisition, based on Krashen's i+1 comprehensible input theory.

ABCD

Complete Beginner

All four lines visible. Learn the script, pronunciation, word meaning and natural translation at the same time.

A — Source language

B — Transliteration

C — Word-for-Word Translation

D — Colloquial Translation

ACD

Can Read the Script

Drop romanization once you can read the source alphabet. Focus on connecting words directly to meaning.

A — Source language

C — Word-for-Word Translation

D — Colloquial Translation

Building Vocabulary

Source and word-for-word only. Try to work out the natural meaning without the translation as a safety net.

A — Source language

C — Word-for-Word Translation

Intermediate

Source and natural translation together. You understand the meaning while still reading the original.

A — Source language

D — Colloquial Translation

Advanced Immersion

Source language only. No translation, no support. Test yourself.

A — Source language

ABCD → ACD → AC → AD → A

Your learning journey. The source language is always present.
