Local-first · Windows · Coming soon

Drop anything in.
Start answering.

Hand langcap a video, a podcast, an ebook, a PDF, or a web page in the language you're learning. It mines questions straight out of your own media and just keeps asking — deciding what's useful next. While it's open, you're answering.

Loading question…

The loop

It doesn't run a lesson. It keeps asking.

No deck, no session, no "done." langcap reads your media, pulls a question, and asks. You answer, and the next one is already there. The feed never ends because your media never runs out of things worth knowing.

It mines your media

A sentence, a word, a turn of phrase from the exact thing you dropped in — never a generic word list.

It picks what's useful next

What you missed, what's due, what's just ahead of you. It chooses the next question; you don't.

And it asks again

Answer and the next one is already there. While the app is open, you're answering — nothing to start, nothing to finish.

Always on

It lives in your tray.
A question is always one glance away.

langcap waits quietly in your Windows tray. Click it to answer a few, or let it surface a question now and then while you work — you decide how often. Close the window and the loop is still there when you come back.

One screen, one question — so it drops into a small popup with nothing to navigate. The whole app is the question. (A dock app on macOS, later.)

Control

You don't manage it. You steer it.

Nothing to organize — no decks to build, no schedule to keep. Nudge what it asks about and let it run.

Want a tighter grip? Point langcap at a local model and steer the questions in your own words. Still nothing leaves your machine.

Local model "keep asking about the kitchen-scene vocabulary"

It reads what you already keep

Got subtitles? langcap picks them up automatically — you don't add them.

Private by design

Nothing leaves your machine.

No account. No upload. No subscription. No cloud round-trip. Your media stays in your folders, the questions are mined locally, and the optional model runs on your hardware. Buy it once and own it.
