Common Portuguese mistakes

Portuguese has two written standards, European and Brazilian, and the checker follows the one your text uses. The usual mistakes are the crase (à and a), accents on words like também and você, mais and mas, and fazer and haver in time expressions, which stay singular: faz dois anos, não fazem.

Tool description

Type or paste up to 5,000 characters of Portuguese text and click Check grammar. The AI marks each mistake right in the text, red for spelling, grammar and punctuation and yellow for style. Under Mistakes, each one has its fix and a short explanation in the language of the page.

Click a mark to find it in the list, or a row of the list to find it in the text. The check button puts the fix in your text, the cross dismisses it, and Apply all fixes everything that's left. You can keep editing: the marks stay on their words, and a mark goes away when you change its word. If the text is in another language, the tool says so and links to the checker for it.

Features

  • Mistakes marked in your text, each with a fix and a reason
  • Fixes applied one by one or all at once
  • European and Brazilian Portuguese both accepted

Limitations

AI can miss a mistake or flag a correct word, so read each fix before you apply it. A text with many mistakes may need a second check after the first fixes.
