AI Content Checker

Check a page before you publish: private on-device AI review, headings, spacing, same-tab and broken links. Free. Check any web page before you publish it. Free, private and no account needed.

AI Content Checker reviews your page with Chrome's built-in AI and checks the details that are easy to miss: headings, spacing, links that open in the same tab and broken links.

Click "Review this page" and Chrome's built-in AI (Gemini Nano) reviews the main content of the page for: ✔ Logical mistakes and inconsistencies ✔ Structure and format ✔ Repetition ✔ Reading experience and engagement ✔ Descriptive image alt text ✔ Unnatural links or anchor text

Each one gets a ✔ or ✖ with a short explanation, followed by general feedback and suggested improvements.

• Headings: see the H1- H6 outline right on the page, with warnings for a missing or duplicate H1, empty headings and skipped levels.
• Spacing issues: double spaces, spaces before punctuation, missing spaces after punctuation and stray spaces inside parentheses. Click an issue to jump to it.
• Links opening in the same tab: highlights links to other websites that don't open in a new tab.
• Broken links: checks up to 200 links on the page and marks broken ones in red and ones worth a manual look in amber. Chrome asks for your permission the first time.

Every check has a Clear button that removes its highlights and leaves the page exactly as it was.
