What is AI Grammar Fixer?
A grammar fixer corrects spelling, punctuation, subject-verb agreement, and awkward phrasing while keeping your wording and tone intact. TextToolsAI's free AI Grammar Fixer reviews a passage and returns a clean version, catching mistakes you'd otherwise miss on a final read. It runs in the browser with no signup.
Why use AI Grammar Fixer?
Use the grammar fixer as the final cleanup pass after the main rewrite and tone work are done. It corrects grammar, spelling, punctuation, awkward phrasing, and readability issues while keeping the message intact.
Grammar cleanup should be the final polish, not the whole review. First fix structure with the Paragraph Rewriter, adapt voice with the Tone Changer if needed, then proofread. For sentence-level help, read how to fix awkward sentences or use the essay writing improvement workflow.
The errors spellcheck misses
Before
Their going to send there feedback about you're report, and its due Monday - me and the team will of reviewed it by then.
Problems
- Homophones a spellchecker ignores: their/there, you're, its.
- "me and the team" as the subject - should be "the team and I".
- "will of" - a misheard "will have".
- Every word is spelled correctly, so a basic checker flags none of it.
After
They're going to send their feedback about your report, and it's due Monday - the team and I will have reviewed it by then.
Why it's better
- they're = "they are"; their = possessive; your = possessive; it's = "it is".
- Correct subject pronoun: "the team and I".
- "will have reviewed" fixes the "will of" error.
- Now correct where it counts - the mistakes readers actually judge you for.
