No app to install. Everything works in your browser — on your phone, tablet, or computer.
How it works
Get a smart subtitle file
Download one that's already made — or create your own from any .srt subtitle file.
Open it with your video
Load the file and your video in the LinguaBlocks player. They play together, in your browser.
Click anything
Words, sentences, expressions — everything is clickable, and everything is explained.
One file works for everyone. Make it once, share it with your class, your friends — anyone.
Why is it free?
Explaining a video with the best AI available costs money — once. Letting a million people use that explanation costs us almost nothing. So we pay once, and watching is free for everyone, forever.
If you can pay, you help keep the project alive. If you can't, don't worry — you're still more than welcome here☺.
