GrammarMama is an AI grammar checker that does more than just fix your text — it explains every mistake in your own native language, so you understand *why* something is wrong and stop repeating the same errors. Check grammar, spelling, punctuation, and style in English, German, French, Spanish, Italian, Russian, Polish, Chinese, and Portuguese. Set your native language once in the settings and all explanations will appear in it — perfect for language learners and non-native writers. Open the side panel, paste your text, pick the language you wrote in (or leave it on Auto-detect), and click Check. You get the original text with errors highlighted in red, a fully corrected version with a one-click Copy button, and a list of issues with the exact fix and a plain-language explanation for each one. You can also right-click any selected text on any webpage and choose "Check grammar" to check it instantly without copy-pasting. GrammarMama is free to use, requires no account, and stores no text.
