Interactive anime subtitles extension with instant translate

September 25, 2026 I'm building the subtitle tool I've been wishing existed

If you're learning a language through shows/anime, you know the subtitle problem:
Subs don't match the dub. They're usually way simpler than what's actually being said - some are decent, most aren't.
Looking up a word kills your flow. Retype it into a translator (slow) or screenshot + AI (slower). Either way, you've lost the scene.
So I'm building a fix. Not a bloated app - a lightweight Chrome extension.

How it works: open your browser, hit play on any video. Subtitles generate automatically. See a word you don't know? Click it - a popup shows the full sentence with that word highlighted and translated, right in context.
No account. No setup. Just works.

Would you use this? What's missing?

September 22, 2026 Bet I'm building the tool you've been waiting for

Wanna tell you that I'm kinda tired of subtitles nowadays, it sucks and the reasons are obviously simple.

You see that I learn English by watching some videos / animes and there are two options:

  1. Subtitles do not match with characters' current speech, and what I saw, that subtitle variant is way simpler than dub one, some subs are decent, but most aren't.

  2. If you need to translate some unknown word, you need to retype it into a translator (too looong) or get the screenshot, send it to AI and wait a translation (too long), also it ruins the flow

So well, what do we have here, a couple of problems that I'm going to fix. It isn't some hard app, it is the lite extension right in your fav browser (chrome based)

Practical use will be like open your browser, turn on some video and enjoy. Subtitles are generated automatically, when you encounter some unknown word, click on it, and the popup with full sentence with highlighted word will appear translated.
It requires no account, works out of the box.

    Have early testers shown that in-video translation actually keeps learners in the viewing flow, or is the main appeal still the idea of not having to switch tools?

      Great question! In practice, they feel like two sides of the same coin: reducing friction is what protects the flow state. ​Whenever someone has to Alt+Tab, open a translator, or manually type out a word, that tool-switching friction completely breaks immersion. The experience shifts from enjoying a story to 'doing study work.' ​By keeping the translation directly inside the video with a single click, cognitive load drops to near zero. From early feedback and personal dogfooding, eliminating that small barrier is exactly what keeps learners watching longer without feeling fatigued. ​Have you noticed this kind of drop-off when using other language learning tools?

        The “keeps learners watching longer” claim is the part I’d want to follow as real usage comes in. Could be useful to compare notes by email sometime, if you’re open to it.
