Learn languages from Netflix, YouTube, and real-world texts with dual subtitles and AI
View your target language together with a translation, pause, replay single lines, and jump back to the previous subtitle with a hotkey.
Hover or click any subtitle word to see definitions, part of speech, and pronunciation without leaving the video.
Automatically saves looked-up words and phrases, then quizzes you with the original context to build durable recall.
Bring the same translation and lookup workflow to ebooks, PDFs, articles, and other web pages.
Done-for-you YouTube thumbnail and title testing with a money-back guarantee
The team designs, uploads, tests, and reports on every thumbnail and title variant, so you only review the shortlist and the results.
Tests run inside YouTube Studio's own tool against real impressions and viewers, so results are measured rather than predicted.
If the challenger loses or the test ends inconclusive, that test is refunded in full; winners stay live and keep earning.
Effort goes to existing videos where residual impressions and dated packaging make a repackage most likely to win.
