Lanna creates a complete English lesson in less than 30 seconds from any topic. You choose the subject that interests you (cooking, soccer, job interview, any of them), the level, and the AI generates real sentences with natural audio, word-by-word translation, and exercises. Here I show you the step-by-step with a real example.
Look, I’ve always said in my videos that the ideal study material is understandable, interesting, and has the right characteristics. The problem is that finding this material used to take hours. You would go to YouTube, sift through 10 videos, find out that half were too difficult or too boring, choose one, and put together a lesson by hand. Exhausting.
Now it’s changed. In 2026, Lanna creates this complete lesson for you in less than 30 seconds. You say the topic, the level, choose the voice, and in half a minute you’re studying. No more sifting, no wasting time, no losing motivation before you even start studying. In this post, I show the step-by-step with a real example.
The process in 4 steps
Real example: let’s create a lesson on "ordering food in a restaurant in the USA"
To make it concrete, let me show you a real lesson that Lanna just generated now at B1 on this topic:
All this in 27 seconds. Without you having to hunt for content, without outdated textbooks, without wasting time. You opened it, chose the topic, and you’re studying.
Why free topics are better than textbooks
Textbooks teach about things you will never use in your dreams. "The Smith family is going to the museum on Saturday." When was the last time you talked about the Smith family going to the museum? Never. But you talk about your job, your favorite food, your travel plans, the team you root for, every day.
When you study with a topic that interests you, three things happen:
- You maintain interest. It doesn’t become a chore. It becomes a hobby. You WANT to open the app the next day.
- The vocabulary becomes useful. You learn words that you will REALLY use, not decorative vocabulary.
- The context aids memory. The brain retains better things connected to personal interests.
This connects with the concept of comprehensible input from Krashen — the best input is one that is both understandable AND interesting. Free topics cover both.
10 topic ideas to create right now
- Your work routine: "morning standup, email, meeting, lunch break" — useful vocabulary for your career
- Your hobby: "mountain biking", "painting watercolor", "playing chess" — gives extra motivation
- Favorite recipe: "how to make beef stroganoff" — you learn while cooking
- Movie you watched recently: "discussing The Bear Season 3" — cultural vocabulary
- Sport: "F1 race weekend", "NBA finals" — technical words for what you enjoy
- Trip you’re going to take: "checking in at the hotel in New York" — practical prep
- Job interview: "tell me about yourself for a software dev role" — straight to the point
- Casual conversation: "small talk at a coffee shop" — social hook
- Current news: "the new tariff policy" — newspaper vocabulary
- Technology: "explaining what an LLM is" — modern vocabulary
Each of these topics generates a complete lesson in 30 seconds. You can create 10 lessons in 5 minutes. It’s absurd compared to 1980 when you had to go to the bookstore and spend R$80 on a textbook.
How to combine this feature with the rest of the method
Creating a lesson is just the beginning. Once it’s there, you use Lanna’s other modes to explore:
- Audio + text: listen to each sentence pausing, read word by word, save anything new
- Pronunciation: record each sentence, AI gives a score, repeat until you pass 90%
- Speaking: converse by voice with AI about the topic, freely
- Flashcards: review saved words with spaced repetition
- Writing: write a paragraph about the topic, AI corrects
This is the routine I recommend in the complete guide on how to use AI to learn English. Each created content becomes the basis for a 20-30 minute session covering various skills.
Frequently asked questions
How does it work in 30 seconds?
The AI generates sentences at the chosen CEFR level, adds natural TTS audio, and word-by-word translation. All automatic.
Any topic?
Yes. Cooking, sports, programming, slang, travel, work — anything you can describe in one sentence in Portuguese.
Is the audio robotic?
No. The free plan uses modern TTS (gpt-4o-mini-tts), Pro uses ElevenLabs HD. Practically human.
Does it work in all languages?
13 main languages (English, Spanish, Italian, French, German, Portuguese, Russian, Dutch, Japanese, Korean, Mandarin, Arabic, Hebrew).
How many lessons in the free plan?
3 per month. Pro is unlimited.
Different from asking ChatGPT?
Very much. ChatGPT gives text. Lanna gives text + synchronized audio + translation + exercises + flashcards + history.
So, what topic will you create first?
My suggestion: start with something YOU already enjoy. Don’t choose "corporate vocabulary" because you think you should. Choose "F1" if you watch F1. Choose "sushi" if you eat sushi. You will study more and better with a topic that excites you.
The free plan has 3 contents per month — you can create 3 different topics this month and see if the method works for you.
