GrammarChecker.top is a Portuguese language grammar checker project. It uses a hybrid architecture combining rules and statistics to check common Brazilian Portuguese grammar errors. Our sitechecks for both verbal and nominal agreement, and verbal government. It also suggests corrections when errors are detected.
A Brazilian Portuguese grammar checker tool can also be found on Google Chrome. These extensions work by generating tokens for each word in a sentence and checking them against an orthographic dictionary for variations in meaning and grammatical classification. Often, these tools are limited in their accuracy and offer no solution for mistakes, which means they're not helpful to most people. Portuguese grammar checkers help you write better in Portuguese!
