A second brain for learning English.

Mem2n records every word, sentence and mistake. Its AI uses that memory to time your reviews, explain your mistakes and tailor every session to you.

From meeting a new word to using it yourself

Six steps Mem2n takes with you. Everything you do is written to your Memory, so each review lands where you need it.

1Save while reading

Find a good word while reading. Save it.

Highlight a word and press Save. AI fills in the Vietnamese meaning, and Mem2n keeps the sentence you found it in and the name of the article.

Read an article you pasted

2Multi-level review

From recognizing a word to writing with it.

Type a word from the same family and Mem2n tells you which part of speech the gap needs, then lets you retype; the back of the card shows the whole word family. At the next level you write your own sentence from the Vietnamese meaning, and AI grades it and suggests a more natural way to say it.

Type “agreement”, get told the gap needs a verb

3Exercises and tests

Paste a test. Take it right on the web.

Paste a TOEIC Part 5 test and Mem2n turns it into multiple-choice questions you can answer, submit and score.

4A tutor that asks why

Not just the answer, but why you missed it.

The tutor asks what you were thinking when you chose, diagnoses the mistake in Vietnamese, then suggests words to save to Memory.

5Review past mistakes

Today’s mistake, tomorrow’s strength.

Wrong answers go into your mistake log and come back at spaced intervals, sometimes as a new AI-made question on the same point. Get it right enough times and it leaves the log.

6AI that knows you

The more you learn, the better it knows you.

From what is recorded, the tutor finds the mistake patterns you repeat and maps your knowledge: learning, solid, needs practice. Only you can see it.

Questions

Is Mem2n free?
It is free for now. Each account has a daily AI allowance to keep costs in check; normal use almost never reaches it. If a paid plan comes later, you will be told in advance.
How is it different from Anki or flashcards?
Flashcards help you recognize a word when you see it. Mem2n goes further: each word is saved with the sentence you met it in, reviewed in levels from filling a gap to writing your own sentence, and linked to the questions you got wrong so you practice exactly where you are weak.
Do I need to prepare reading material?
Yes — Mem2n learns from your own material: an article, a book chapter, an exercise sheet. Paste it in and start reading.
Can I use it on my phone?
Yes. Mem2n runs in the browser and its layout adapts to phone screens. Sign in with the same Google account and your data is on every device.
How is my data used?
Your articles, cards, exercises and what AI notes about you are visible only to your account. To delete your account and data, send a request through the Contact page; it is deleted within 30 days. More in Privacy.
