Language learning tool suggestion

I’m currently on a working holiday in Japan and trying to soak up as much Japanese as I can while living here.

I started with tools like Language Reactor (a Chrome extension that shows dual subtitles and lets you look up words) and Anki for flashcards. Language Reactor worked great — but only on mainstream platforms like Netflix and YouTube. Most Japanese platforms like Abema don’t come with built-in subtitles, so I hit a wall pretty quickly.

Then I tried Chrome's Live Caption — it can generate subtitles for any audio, which sounded like a game-changer. But it came with a big catch: you can’t copy or export the text, and it’s weirdly buggy sometimes (like captions just not showing even when turned on). Not ideal when you just want to quickly grab a phrase and paste it into Anki.

I came across extensions like Transcribe Audio and Felo. Both offer real-time transcription with decent latency, but they’re not free.

So I started wondering: is there a more DIY or lightweight option? Ideally something that:

• captures real-time audio from browser/system
• transcribes it into editable text
• makes it easy to copy/export to flashcards or notes

Still exploring — if anyone else is learning Japanese (or another language) this way, I’d love to hear what tools or hacks you’ve found helpful. Always open to trading workflow ideas.
