Instant translation by pointing at a word
Hover your cursor over an unfamiliar word in the subtitles to get an instant translation. Video playback will automatically stop, and we will show you the translation of the word as well as its context. If you would like to learn this word, you can save it immediately (by clicking on the asterisk) or do it later in your personal profile.

Personal profile with dictionary, history and frequently checked words
In your personal profile you can see all the words you have ever checked along with their translations and context. Filters and searches help you to quickly find what you need. Separately, we'd like to highlight the ability to see words by how often they are checked - these are the words you should learn first.

Learn words in your favorite app
There are several mobile apps already connected to InterSub to memorize your saved words.

To connect the app, scan the QR code in your profile in Personal profile. If you use a different app, you can always export your words as an Excel file and upload them into it.

Subtitle Navigation
If you didn't manage to read the subtitle or move your cursor over a needed word, you can quickly return to it using the cursor buttons (⬅️ or ➡️) or the arrows to the right and left of the subtitle block.

Auto pause on cursor movement
To help you avoid missing a word or a subtitle, we made an auto-pause mode, which is activated in player full-screen mode after 5 seconds of mouse inactivity. Thereafter, any movement puts the video playback on pause. It is possible to unpause the video by clicking in the player area or by pressing the space bar.

Autodetect languages
Usually, we can define the target languages automatically - the source language we get from a video and the target language we get from your browser settings. But sometimes the detection does not work completely or correctly. In this case, you can choose to set the languages manually in the settings of the plugin or translation window (icon ⚙️).

Tip: How to watch videos better
Auto-pause may not be enough to keep up with fast video speech. Use the space bar to pause and review subtitles. Most platforms recognize the space bar as a play/pause command. If you missed anyway, use the cursor arrows (⬅️/ ➡️) or the right/left arrows near the subtitles to navigate.
