How it works

Three steps to fluency

Step 01

Import content

Paste a URL, upload a PDF, snap a photo, or let AI generate material at your level.

Step 02

Read & look up

Read through native content. Click any word for instant definitions. Highlight and annotate as you go.

Step 03

Review & retain

Saved words enter spaced repetition. Track streaks, daily goals, and progress to stay on track.

Features

Everything for input-based learning

Built around the idea that massive comprehensible input is the fastest path to fluency.

Import from anywhere

Paste URLs, upload PDFs, snap photos of textbooks — or paste raw text. Your real-world content becomes interactive study material.

YouTube transcripts

Paste a YouTube link and study the transcript side-by-side with the video. Every word is clickable.

Instant word lookup

Select any word to see definitions, readings, and pronunciation instantly. No tab-switching, no copy-pasting.

SRS vocabulary review

Words you save go into spaced repetition with context sentences. The algorithm adapts to what you actually struggle with.

AI lesson generation

Describe a topic, pick a level, and get a full reading lesson generated in seconds. Never run out of material.
