How it works
Three steps. No friction.
01
Add your style guide
Paste your writing rules as plain text, or upload a .txt or .md file. Choose from eight built-in examples — journalism, business, LinkedIn, PR, and more — or paste your own.
02
Paste your draft
Drop in any piece of writing — blog post, LinkedIn update, newsletter, press release, anything. Hit Check Style. Claude reads both and identifies every rule your draft breaks.
03
Fix and export
Violations are ranked by severity. Each one shows exactly what's wrong and proposes a specific rewrite. Apply fixes with one click, then export your revised draft as .txt or .docx.
