AI Grammar Checker

The AI Grammar Checker corrects spelling, grammar and punctuation, then shows a table of every change with a reason, so you can accept or reject each fix.

It is built for bloggers, consultants and site owners who write client emails, posts and page copy and want a quick proofread without giving up their voice.

1. Paste your text: Add up to 4,000 characters.
2. Run the checker: The tool sends the text through this site to Google’s Gemini model with instructions to fix errors and leave voice alone.
3. Read the table of changes: Each row shows what changed and why. The table lists up to 20 changes per run.
4. Keep or reject changes: If a change alters what you meant, keep your original wording.
5. Copy the corrected text: Copy the result into your document or CMS.

A short paragraph with common errors.

The corrections above are typical, not a fixed output.

• Proofread emails, posts and page copy in seconds.
• Learn why each fix was made from the reason column.
• Avoid rewrites that change your voice, because the tool is told not to.
• Check client deliverables before you send them.
• Catch homophone mistakes such as their, there and they’re.

I compared this with the free AI grammar checker on embarque.io, read from its page on 22 October 2026.

Where they are ahead: embarque.io also suggests style and tone improvements and states no usage cap. This tool sticks to errors and keeps your wording.

Compared on 22 October 2026 by opening each tool and reading its page. Features can change.

• It fixes errors only. It does not rewrite for clarity, style or tone.
• It can miss mistakes or flag correct text, so read the result.
• It works best on English.
• Each visitor can run this tool 5 times an hour, and a daily cap across all AI tools on this site means it can pause on busy days.
• The table lists up to 20 changes per run, and input is limited to 4,000 characters.
