Grammar Checker — Complete Guide & Instructions
MakeCard Grammar Checker proofreads your English text for spelling mistakes, grammatical errors, and style issues using the public LanguageTool engine — the same rule base trusted by editors and non-native speakers worldwide. Paste your paragraph, click Check Grammar, and every issue appears as a labelled card showing the flagged phrase and a suggested correction. One-click Fix buttons apply each suggestion directly into your text, so you can polish an email, essay, or post in a single pass.
How to Use Grammar Checker
- 1 Paste your English text into the input box — sentences, paragraphs, or a full draft.
- 2 Click "Check Grammar" and wait a moment while the text is analysed.
- 3 Review each issue card: the coloured badge shows whether it is a misspelling, grammar, or style problem.
- 4 Read the flagged phrase (struck through in red) next to the suggested correction (green).
- 5 Click "Fix" on a card to apply that correction to your text, or skip it if the original was intentional.
- 6 A green "No issues found" banner means your text is clean.

Pro Tips for Best Results
- Apply fixes one at a time and re-read the sentence — automated suggestions occasionally change meaning.
- Style suggestions are opinionated; keep your own voice where a suggestion flattens it.
- Break very long documents into sections if the check feels slow.
- Do not paste passwords, personal IDs, or confidential business text — it goes to a third-party API.
Common Problems & Solutions
The free LanguageTool API has rate limits and occasional downtime — wait a minute and retry, or shorten the pasted text.
Grammar engines do not understand intent. Review each green suggestion in context before clicking Fix; skipping a suggestion is always safe.
