Grammar Checker

Review a short English draft for a small set of common typos, spacing issues and missing punctuation. This rule-based checker keeps existing capitalization such as NASA intact and lets you inspect the suggested text before copying it.

How to check a draft

1. Paste your text or choose Load Sample.
2. Select the check button to see the revised text and correction notes.
3. Compare the result with your original. Copy it only after reviewing names, meaning and punctuation.

Examples

I work at NASA. remains unchanged and reports 0 issues. i recieve teh report becomes I receive the report. and reports 4 correction types: the pronoun, two typos and closing punctuation.

Rules and limits

The checker fixes a short list of misspellings and contractions, repeated horizontal spaces, spaces before punctuation, lowercase sentence beginnings and missing closing punctuation. Paragraph breaks and existing acronym capitalization are preserved. The Issues metric counts types of correction, not every occurrence.

It does not understand context, verify facts, recognize every proper name, or provide comprehensive grammar checking. It can miss errors and may suggest changes you do not want. Review quotations, abbreviations, technical terms and code manually.
