InterSub
Overview
InterSub is an AI-driven tool designed to enhance language learning through the usage of interactive dual subtitles while consuming content online. Geared toward English, Spanish, and other languages, it operates across multiple platforms such as YouTube, Netflix, Prime Video, Coursera, etc., making it versatile and flexible to use.
InterSub's main function revolves around AI-assisted subtitles, wherein it displays subtitles in both the user's native language and the target language.
Even in the eventualities where the video lacks subs in user's language, InterSub provides real-time translations. One of its significant features includes instant translations, allowing users to hover over any word in the subtitles to receive instant AI-generated definitions and contextual translations.
The tool also offers a Personal Wordbook, where all translated words get automatically saved for easy review and self-study. Furthermore, users can sync this wordbook to other mobile apps or Telegram bots for learning on the go.
InterSub also allows users to look up words on virtually any site, supports collocation detection for nuanced linguistic insight, and permits remote control usage for user convenience.

Chat with 3D avatars to learn languages interactivelyg k🙏 25 karmaJun 30, 2025@AvatalksThis is hands-down the most engaging language app I’ve ever used. The AI conversations feel real, and the talking avatar makes it fun to practice speaking without anxiety. -
Break through the fluency barrier.I tried a chat section. It's pretty cool, I used another company that's very similar to yours but it didn't recognize speech nearly as well as yours does. The only negative feedback I have for you is the web app seems a little bit buggy on my phone sometimes when you click to hold down for speech it doesn't work very well you have to try it a couple times. I like it though I'm going to try it again.

Master languages 6x faster by chatting with AIThe app looks interesting, but it's not free. The free version is very limited, and the premium version seems expensive, although it may be worth it.
