About

Learn English from what you already watch and read. Hover a subtitle on YouTube or Netflix, or select text on any web page, and see what it means in your own language, idioms and all. Save the phrase with the sentence it came from. Smart Review brings it back at the right time, as a gap in your own sentence, so it sticks. Then an AI voice coach practices those exact phrases with you out loud, so the words are there when you need them.

AI Summary

Subturtle is a Chrome extension that helps users learn English by providing translations and context for subtitles and selected text from online content. It features a Smart Review system and an AI voice coach to reinforce learning through practice.

Scored deterministically. Only candidates that fire a story trigger are sent to a model, so this one has no written angle.

ThinLittle evidence and no strong angle. Nothing to build on yet.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
