ChatGPT and Lanna tackle different problems. ChatGPT is a powerful generalist for specific questions and free conversation. Lanna is a structured language method with voice-corrected pronunciation, spaced flashcards, and progress history. Here I compare feature by feature, show who wins in each area, and explain when to use each one (or both together).
Every week someone asks me: "Renyer, can I learn English just with ChatGPT? Do I really need a language app?" Fair enough. ChatGPT in 2026 is incredibly good — it chats, corrects, explains, simulates interviews. It seems to do everything. So why did we spend 2 years building Lanna (a Brazilian AI language learning platform)?
In this post, I will be direct and honest. I will compare feature by feature, point out where each one wins, where they tie, and in the end, I will tell you who should use each one — or both together. No bias towards our side. I promise.
The fundamental difference between them
ChatGPT is a generalist, Lanna is a specialist. This changes everything. ChatGPT was made to answer any question on any topic — coding, recipes, writing, math, languages, philosophy. Lanna was made for one thing only: you to learn a language the right way, every day, measuring progress.
When you ask ChatGPT "help me learn English," it does its best within the limitations of a generic chat. When you open Lanna, the entire method is already ready: content at your level, navigable audio, word-for-word translation, corrected pronunciation, flashcards, exercises, grammar, speaking. It's not a competition; it's a different category. But we can compare the features.
Feature by feature comparison
Here’s the complete table. Each row is a feature, and who wins in each:
Direct score: in 8 out of the 11 specific language learning features, Lanna wins. ChatGPT wins in 2 (complex technical explanation and more flexible interview simulation) and ties in one (writing correction). This makes sense — ChatGPT is a generalist, Lanna is a specialist.
Where ChatGPT truly shines
To be honest: there are things that ChatGPT does BETTER than Lanna, and it's worth mentioning.
- Very specific grammatical doubts. "What’s the difference between since and for when used with present perfect?" — ChatGPT explains with 20 examples in 5 seconds. Lanna also explains, but ChatGPT is more flexible because you can ask in a thousand different ways.
- Single scenario simulation. "Simulate a conversation where I’m resigning in English" — ChatGPT improvises better for unique scenarios.
- Long text revision. Paste a 500-word email and ask for correction — ChatGPT gives detailed feedback in seconds.
- Explanation in other languages. Want the explanation in German to train two languages at once? Just ask.
These 4 points are real cases where you should use ChatGPT. I use it myself.
Where Lanna is unbeatable
And now the other side. Where Lanna does something that ChatGPT simply doesn't do:
- Pronunciation correction with real score. You record, the AI compares with the target, and gives you a percentage. If it’s 75%, it shows exactly which words you got wrong. ChatGPT doesn’t do this.
- Flashcards with spaced repetition (SRS). Every word you save comes back on the right day for you to review. In 3 months, you’ll have 500 words fixed without conscious effort. ChatGPT doesn’t save anything.
- Transform YouTube into a lesson. You paste the link of a video, and it turns into an interactive lesson with transcription, word-for-word translation, and exercises. Does ChatGPT watch videos? No.
- Measured progress history. How many hours studied, average pronunciation score, how many words fixed, which topics you've seen. You see the evolution, and that motivates a lot.
- Curated content by level. Library with movies, series, TED Talks, interviews, and songs organized by A1→C2. You don’t waste time choosing — just click.
Is ChatGPT cheaper?
Contrary to what it seems, Lanna Pro is cheaper. ChatGPT Plus costs $20 per month — which in Brazilian reais is about R$100-120 depending on the exchange rate. Lanna Pro costs R$39.90 fixed.
With the difference (R$60-80 per month), you could even subscribe to both — Lanna for daily study and ChatGPT Plus for advanced cases. This would make sense for those who need both tools professionally.
So who should use what?
Profile 1 — absolute beginner or stuck intermediate: Lanna. You need structure, method, step-by-step guidance, spaced repetition. ChatGPT without structure turns into a random chat with no real progress.
Profile 2 — advanced who already speaks well and wants to refine: both. Lanna for daily routine (maintaining fluency, learning specific vocabulary, shadowing with new video), ChatGPT for point cases (work text revision, presentation simulation, fine grammatical doubts).
Profile 3 — someone who just wants to clear occasional doubts: ChatGPT. If you’ve studied English in your life and just need an assistant to consult, ChatGPT is the most practical. You don’t need the method.
Profile 4 — language teacher: both, no doubt. ChatGPT for preparing lesson material, generating exercises, creating scenarios. Lanna for interactive teaching to students, measuring their progress, and in presentation mode, creating slides with the 10 widgets. If you’re a teacher, this post about teaching languages online has more context.

Frequently asked questions
For beginners, which is better?
Lanna. ChatGPT requires that you already know how to ask basic questions in English. Lanna guides from scratch.
Which has a free plan?
Both. ChatGPT free has GPT-3.5, Lanna free has 3 contents per month. Start on both before paying.
Which corrects pronunciation?
Lanna. ChatGPT understands your voice but does not compare it with a target to give a score.
Can ChatGPT give wrong information?
It can — this is called hallucination. For basic/intermediate English, it’s rare, but for very specific rules, confirm with another source.
Can you combine both?
You can, and I recommend it. Lanna for routine, ChatGPT for occasional doubt.
Which saves more time?
Lanna. You open it and it's ready for you to study. ChatGPT requires you to write the right prompt every time.
So, final verdict
If you’re only going to choose one, choose Lanna — unless you’re someone who already speaks English reasonably well and just needs a general assistant. To truly learn, a structured method beats a generic chat.
But honestly: you don’t need to choose. ChatGPT is free or cheap, and Lanna has a free plan. Try both for 1 week and you’ll feel for yourself where each one works better for you.
