Content you actually care about
No more scripted audio. Use vlogs, documentaries, podcasts, shows, or tech channels. The language real speakers use — not the textbook kind — with whatever accent they happen to have.
Fill-in-the-gap with YouTube
Learn languages with
real content
Pick a YouTube video — a travel vlog, a tech talk, a news segment — and train your ear by filling in the gaps of its real subtitles.
- English
- Español
- Français
- Deutsch
- Italiano
- Português
- Català
We give you the language. You pick the accent — the channel you follow decides whose voice your ear gets used to.
Why Gappier
You type it, you don't just watch it
A gap waits for the word and the video keeps going. You cannot skim past what you failed to catch — that is the whole difference between watching with subtitles and actually practising.
What you miss comes back
Every word you get wrong lands in one review list, whether you missed it on the web or on YouTube through the extension. You reinforce it later on the web, each word in a sentence of its own.
Three steps. No excuses.
-
Pick your video
Any YouTube video with subtitles in the language you want to learn. A show episode, a programming tutorial, a TED talk — your call.

-
Fill in the gaps
The video plays. You listen and type the missing words in sync with the audio.
Coming soon
Practice without leaving YouTube
The Gappier extension for Chrome drops the gaps straight onto the video you're already watching. Same account, same progress — you just stop switching tabs.
- The exercise runs on youtube.com, over the video itself.
- Your history, your streak and your missed words stay in sync with the web app.
