Catch Grammar and Phrasing Issues Before You Hit Publish

Paste your text and get grammar, punctuation, and phrasing corrections, with the reasoning explained so you actually learn from the fixes.

What is the AI Grammar Checker?

The AI Grammar Checker reviews text for grammar mistakes, punctuation errors, awkward phrasing, and word choice issues, then suggests corrections you can accept individually. It covers the usual suspects — subject-verb agreement, comma splices, misused apostrophes — as well as subtler issues like run-on sentences and unclear pronoun references that spellcheckers typically miss.

It's meant to work on anything from a two-sentence email to a full article, catching errors without rewriting your voice into something generic. The focus is correctness and clarity, not overhauling your writing style — if a sentence is grammatically fine but stylistically flat, that's a job for the tone changer or content rewriter instead.

Subject-verb agreement

Input

"The list of items are on the table."

Output

"The list of items is on the table." — flagged: 'list' is the subject, so the verb should be singular.

Comma splice

Input

"I finished the report, I sent it to the team."

Output

"I finished the report, and I sent it to the team." — flagged: two independent clauses need a conjunction or a period.

Tips that improve results

  • Read the explanation for each flagged issue, not just the correction, to avoid repeating the same mistake.
  • Don't accept every suggestion blindly — some flagged 'errors' may be intentional stylistic choices.
  • Run longer documents through in sections for easier review of each suggestion.
  • Pair it with the tone changer if you also want to adjust style, not just fix errors.

Mistakes worth avoiding

  • Accepting every suggestion without understanding why the change was made.
  • Assuming grammar checking also covers factual accuracy, which it doesn't.
  • Skipping a final read-through after applying corrections.
