Watch anything with interactive subtitles
Drop in a local video file. Click any word in the subtitles for an instant definition with pitch accent (where supported) and exam level. One click turns it into a flashcard with the video screenshot as context. You can also use it in your browser for streaming sites.


Subtitles over any app
A transparent, always-on-top subtitle window for any video player — Netflix, YouTube, VLC, your own files, whatever. On YouTube, subtitles are grabbed automatically: just turn them on in the player and they appear in the overlay, no file needed. Click or hover any word for instant lookup and one-click flashcards. It also works as a web overlay: long-press any word on any website to look it up without leaving the page.


Read manga and PDFs with OCR
Open a folder of images or a PDF. mLearn runs OCR in real time — hover any text for instant lookup, just like video subtitles. Double-page spread, fit-to-height, magnifying glass, reading aid hider — it's all there.

Flashcards that build themselves
Every word you click in a video or manga can become a flashcard automatically — with the screenshot, audio, and context sentence included. The SRS handles the scheduling. You just review.

AI tutor when you need help
Stuck on a grammar point? Ask the built-in AI for an explanation in context. It runs locally on your machine — no internet needed, no data sent anywhere. Voice mode is also available if you want to practice speaking.

Watch native content
Hover over words to view their definitions, or adjust your knowledge of them, whether you're on mobile or on PC/Mac.
It remembers what you see
mLearn passively tracks every word you encounter across videos and books. See a word ten times but still hover it? The app notices and can automatically flag it for review. You don't have to manually mark everything.

Smart vocabulary assessment
Don't know where to start? The word sync tool tests your vocabulary efficiently using weighted sampling. It prioritizes words with characters you already know, skips words you're solid on, and cross-checks your Anki deck.

Phone and desktop, synced
Study flashcards on your phone, watch videos on your desktop. Flashcards and settings sync via a QR code scan — data transfers directly between your devices. We do not keep copies of your data.

Watch together, learn together
Sync video playback with friends or students.
They don't even need the app — the browser link gives them synced subtitles and watch-together.
Intelligent lookups require the mLearn app running in the background.

7 themes
Light, dark, darker, high contrast, glass light, and glass dark. Pick what feels right. The UI stays out of your way so you can focus on the content.

Character knowledge tracking
mLearn lets you know how many characters you can read based on words you know.* You can also filter characters based on exam level requirement.**
Paste a video URL or drag a file into mLearn. For streaming sites, install the browser extension and click the mLearn icon.
For manga or PDFs, drag the file or folder into the Reader. OCR runs automatically.

The app usually draws less power than a web browser. AI features use more resources when active, but everything else is lightweight. Great for long study sessions on battery.
