Browser extension
Check everywhere you write
Select text on any page and run any Clever Checker tool in place. Same checkers, same reports, no copy and paste.
Free to add. Works with your Clever Checker account.
What it does
The whole toolbox, in the tab
Select, then check
Highlight a paragraph in your doc, your inbox or your CMS and pick a tool. The extension reads the selection so you never leave the page.
The same result
Reports render from the exact layouts the site uses: the hedged AI confidence score, per-sentence highlights, matches and issues. Never a bare verdict.
Rewrite in place
Paraphrase or humanise a selection and drop the result straight back into the field you were editing. Only when you ask it to.

Your text is handled exactly as it is on the site: sent only to run the check, then deleted on the same schedule. Details in Privacy.
