Who is Cláudia for? Adults (18+) who speak Portuguese, mostly in Brazil, and want to practice speaking English, Spanish, French, Italian or German.
Not for: people who don't read Portuguese (the app interface is in Portuguese), people who want to learn Portuguese, and people who need a certificate.
What Cláudia is
Cláudia (webclaudia.com) is a language app made in Brazil for people who speak Portuguese. The idea is simple: most people who studied a language for years understand much more than they can say, so the app puts speaking at the center. You talk out loud with an AI tutor called Cláudia, drawn as a small cloud with purple headphones, and she answers out loud.
Cláudia is software, not a person, and the AI can make mistakes. It is not a course with a certificate and it does not guarantee fluency. Use is for adults (18+).
How a conversation works
You pick a topic and talk. She answers by voice and, when something comes out wrong, she points it out right away and gives you the right sentence to repeat. When you can't talk out loud, the same conversation continues by text.

Tell me about yourself. How old are you?
I have 25 years
Almost! In English, age goes with the verb to be: I’m 25 years old. Can you say it again?
I’m 25 years old
That’s it! Now tell me: what do you do?
Sample conversation in the all-English mode
That sample is the all-English mode. With “Com uma mão do português” (with a little help from Portuguese), she explains the mistake in Portuguese when needed, which is the easier start for beginners. With “Tudo em inglês” (all in English), the whole conversation stays in the language you are practicing.
On a voice call there are two ways to take turns: “Um toque abre, outro fecha” (one tap opens the microphone, another closes it) or automatic, where she notices your silence and answers.
What there is to practice
- In every language: free conversation by voice or text, on the topic you choose, with instant correction.
- In English, also: a daily lesson with a report, pronunciation practice with a score for each word, a scripted conversation, and everyday situations where she plays the other person (travel, business and food). If your situation is not on the list, you describe it in a few words and she sets it up.
- Habit: a word game against the clock, a streak of days and missions.
Three moods, including the strict one
You choose how Cláudia talks to you. The names below are the ones shown in the app, in Portuguese.

“Céu limpo” (clear sky)
Calm and patient
Slipped up? No problem: you repeat it together until it sounds natural.

“Nublado” (cloudy)
Direct, no fluff
A one-word “yes” does not count: she wants a full sentence, with subject and verb.

“Tempestade” (storm)
The strict one, 18+ only
The tough teacher, with swearing. Before turning it on, you confirm that you are 18 or older.
Languages
