How does spaced repetition work in Lanma?

Lanma uses a 6-stage spaced repetition system. Each word starts at mastery level 0. As you review correctly, the word advances through stages with increasing intervals: 1 day, 3 days, 7 days, 14 days, 30 days, and 90 days. If you miss a word, it moves back so you can review it sooner.

Can I create my own word sets?

Yes. Lanma is built around custom word sets that you create yourself. Add words with their meanings, definitions, and notes. Free users can create up to 5 word sets with 30 words each. Pro and Premium users have unlimited word sets and unlimited words per set.

Can I share my word sets with others?

Pro users can share word sets via a public link. Anyone with the link can view the word set and study the vocabulary, even without a Lanma account.

What is the difference between Free, Pro, and Premium?

Free: YouTube and AI word set generation (3/month each), up to 5 word sets, and 30 words per set; AI Chat is not included.

Premium ($9.99/month): unlimited word sets, unlimited words per set, YouTube generation (30/month), AI word set generation (30/month), AI Chat (30/month). All plans are completely ad-free.

No. Lanma is ad-free on every plan, including the free plan. There are no banner ads, no video ads, and no sponsored content. The app is funded entirely through Pro subscriptions.

What quiz modes does Lanma offer?

Lanma offers two quiz modes: multiple-choice and typing. Multiple-choice quizzes test recognition by showing four options. Typing quizzes test active recall by requiring you to type the answer. Both modes track your progress and feed into the spaced repetition system.

What are the AI features?

AI features are available on every plan with different limits. Free users get 3 YouTube and AI word set generations per month; AI Chat starts on Pro. Pro users get higher limits and AI Chat (5/month). Premium users get the highest limits and AI Chat (30/month) with grammar corrections and report cards.

How does AI Chat Practice work?

Choose a word set, select a difficulty level, and pick a scenario like cafe ordering or job interview. The AI tutor guides you to use your vocabulary naturally. After each message, you get grammar corrections. When done, you receive a report card with scores and personalized improvement suggestions.

How does YouTube vocabulary generation work?

Lanma extracts the transcript from any YouTube video, then uses AI to identify key vocabulary words with definitions, example sentences, and context from the video.

Can I use it with any website?

Yes. Paste any article, blog post, or news page URL and Lanma will extract the text and generate vocabulary from it.

How is AI Chat different from ChatGPT?

HOW IT WORKS

Inside the algorithm

Lanma uses SM-2+, a refined version of the spaced repetition algorithm trusted by medical students and polyglots. Here's exactly how it decides when to show you each word.

Every word has a learning state

New

First time seeing this word

Learning

Actively memorizing with short intervals

Review

Graduated to long-term review

Relearning

Forgotten during review, back to short intervals

You grade each word honestly

After seeing the answer, you tap one of three buttons. Your choice tells the algorithm exactly how well you remembered.

Unknown

Don't remember — reset and show again soon

Unsure

Partially recalled — interval grows slightly

Known

Remembered perfectly — skip ahead with a longer interval

Intervals grow as you remember

Each correct answer multiplies your review interval by a personal ease factor. The better you know a word, the longer before you see it again.

Six levels of mastery

Your review interval determines your mastery level. As intervals grow, you progress through six stages — from first encounter to fully mastered.

New

< 1 day

Familiar

1 – 7 days

Practiced

7 – 21 days

Confident

21 – 60 days

Strong

60 – 180 days

Mastered

180+ days

The result: you spend time on words you're about to forget, not words you already know. No manual scheduling, no guesswork — just science.
