Caderno: Diário em inglês

Caderno is an English-language diary created for Brazilian Portuguese speakers.

Write a few lines about your day and receive clear corrections, more natural alternatives, and explanations in Portuguese. Instead of following a long course, you practice with your own experiences and with the words you actually want to use.

With Caderno, you can:

- write a personal diary in English
- identify frequent errors while writing
- request AI review whenever you want
- compare the original sentence with a corrected version
- understand the reason for each change in Portuguese
- track your consistency and review calendar entries
- record your daily mood
- write and edit entries without connection

AI review helps with verb tenses, articles, prepositions, vocabulary, and unnatural expressions. The explanations help you learn from the error and reuse the sentence in another situation.

The Notebook is ideal for those who want to:

- develop the habit of writing in English
- practice beyond multiple-choice exercises
- gain confidence before using English in conversations or messages
- keep a personal record of their own progress

By default, entries are saved on the device. The text of an entry is only sent when you explicitly request AI review.

Start with a sentence. Tomorrow you'll have another page.
