How to remember the language from shows you've already watched
You watched the whole series in your target language. It felt like studying — and a week later almost none of the language stuck. This is the most common trap in learning from video: watching is input, but without recall, most of it washes out.
Here is how to fix that without re-watching everything.
Why re-watching and hand-mining both fall short
Re-watching helps a little, but it's slow and passive — you recognize words in context without ever being asked to produce them, so recognition never turns into recall. The disciplined fix is "sentence mining": pause on a good line, look it up, copy the sentence and a screenshot into Anki, tag it, move on. It works. It's also enough work that most people quit within a week.
The move that actually sticks: turn the shows you've already finished into active recall, with each question tied back to the exact moment it came from — so you're testing yourself on real lines you've already heard, in context.
Doing it automatically
That mining is exactly what Langcap does for you. Drop a video file in — an episode, a film, an anime, a long download — and it:
- Reads the whole thing. It transcribes the audio on your GPU, or uses the subtitles if the file has them.
- Mines it into questions, each stitched back to the clip it came from, and picks what's useful to ask next — what you missed, what's due, what's just past your level.
- Keeps asking, so the vocabulary from that show comes back right as it's fading.
You can also Play the source back with each word lighting up as it's spoken and a translation beneath, then drop into Recall — the question loop scoped to that one show. Long videos and full films work; you don't cut clips by hand.
What's supported
Seven languages have the full experience from video today — English, Spanish, French, German, Italian, Portuguese, Chinese. Anime and other Japanese content, and Korean shows, study from their audio now (great for listening and vocabulary), with the text read-aloud voice coming next. It's a young Windows beta and needs a Vulkan-capable GPU.
