Both languages, at once
The line you hear next to the line you understand — no pausing, no switching tracks.
Learn a language while watching
the videos you love.
Watch with subtitles in two languages, or train your ear by revealing only the words you didn't catch. Save new words to your personal dictionary.
This demo is the real extension, running on this page — select a word to save it, or try a mode below.

One Lingogram, tuned for the site you watch on
Each edition is a separate Chrome extension, built for one site's player — native subtitle tracks, fullscreen overlay, the fixes that site needs. They share the same learning tools and the same account, so your saved words are in one place whichever you use. Two extensions cover all three sites: the YouTube one handles Netflix as well.

From install to first saved word in one video
1Install and pick your languages
Choose the language you're learning and your own. A quick one-time setup — no account needed.
2Open any video with captions
Press play — both languages appear together, on the video and in a transcript that scrolls with the scene.
3Save words, review them on this site
Keep a word in one tap while you watch — then open your dictionary on this site and review it with the scene it came from.
Your dictionary
Every word you save builds a dictionary that's actually yours
Not a frequency list from a textbook — words you met in scenes you chose, kept with the lines they came from. Whatever edition you watch with, everything lands in one account, and it's waiting for you on this site after you log in.

Your words sync across devices and every Lingogram edition — one account, one dictionary.
Most tools stop at translation. Lingogram makes words stick.
Lingogram is based on active recall: you don't just read along — you guess, replay, and collect, so the hours you already spend watching turn into real progress.
Dual subtitles
Two languages, one screen
Catch every line in the original and match it to your own language without pausing. When you're ready, hide the translation — dual subtitles are a starting point, and Lingogram helps you outgrow them.
Interactive transcript
Replay the line, not the movie
The transcript scrolls with the video on its own. Click any line to jump back and loop that one scene until the sounds you couldn't parse become words you instantly recognize.
Guess mode
Listen first, then check
Words start hidden: catch the line by ear, then reveal it. This listen-first loop builds listening you can rely on — not subtitles you only read along to. Toggle it with Shift + G.
Saved words
Your vocabulary, from your movies
One tap saves a word with the subtitle lines around it. It goes straight to your personal dictionary on lingogram.ai, where you review every word in its original scene.
What you watch stays your business
Yes, we collect anonymous usage stats. They help us make the product better, are not tied to your account, and one click turns them off — here's how. Your settings stay in your browser.
We never see your watch history. Subtitles are processed right on your device.
Your dictionary is opt-in. If you sign in, we store your email and your saved words — nothing else, and we never sell them.
We fix it fast. If a site update breaks something, one click reports it so we can fix it fast.
Questions people ask before installing
Is it free?
Yes. Dual subtitles, the transcript, and Guess mode are free. A free account is only needed if you want your saved words synced across devices.
Which languages does it support?
Any pair the video has captions for. On YouTube, if one of your two languages is missing, Lingogram fills it with YouTube's automatic translation so you still get the dual view. On Netflix and HDrezka it shows the subtitle tracks the title actually has — no machine translation.
Which edition do I install?
The one for the site you watch on. There are two extensions: one covers YouTube and Netflix together, the other covers HDrezka. Install both if you watch on both — they share the same learning tools and the same account, so your saved words stay in one place.
Where are my saved words kept?
In your personal dictionary, right here on lingogram.ai. Log in and every word you've saved is there with the scene it came from — whichever edition or device you saved it on.
