Bring Your Own Material

Your material. Your course practice.

Paste an article or YouTube source. AI builds a reviewable draft lesson, you check every exercise before publishing, then review until the material sticks.

Start with Pro custom lists

Pro subscription required. AI draft import uses your custom-lesson allowance.

Your Class. Their Curriculum. It Doesn't Match.

The Problem

Apps Ignore Your Actual Coursework

You're studying Unit 7 of your textbook but the app wants you on their Lesson 1. Your TOPIK vocab list, your professor's handout, none of it fits.

The Solution

Import your source. Let AI build the first draft.

Use the material you actually study. AI creates multiple choice, sentence building, and other draft exercises; you stay in control and edit before anything is published.

The Result

Ace the Exam You're Actually Taking

Your vocab is drilled through review that sticks. Weak words get extra reps. Optional practice with friends can use the same lists when you want stakes.

Import with AI. Review once. Then study.

Go from a source URL to a reviewable interactive lesson without writing every first draft by hand.

01

Drop in Your Content

Paste a public article or YouTube URL. AI extracts the useful language and builds a lesson draft from that source.

02

Review the AI draft

Check every generated exercise, edit anything that needs your voice, and run the content audit before publishing.

03

Review until it sticks

Review brings words back before you forget them—on the same practice path as the built-in course.

Same practice path. Your content.

AI builds the first draft; after your review, the lesson uses the same review and practice path as the built-in course—not just passive flashcards.

Smart Flashcards

Spaced repetition tracks your memory for each word individually. Review intervals stretch as you improve, so you never waste reps.

Real exercises, not only cards

Multiple choice, sentence building, dictation, conjugation drills, and pronunciation practice. Every word gets practised multiple ways.

Optional pressure practice

Optional timed practice and friend matches on the same lists when you want stakes—not the main product.

Weak Spot Tracking

See exactly which words you keep getting wrong. Accuracy trends and response times show where to write more practice.
