Copywritely is SEO content analysis software from the team behind Sitechecker: it finds plagiarism, keyword stuffing and readability problems in your pages, then guides the rewrite inside an interactive editor until the content is fit for people and search engines.
Most SEO content tools stop at telling you a page is weak. Copywritely is built around fixing it. Paste a text or point it at a page and the checker runs a comprehensive analysis: a uniqueness scan against billions of web pages for plagiarism, a keyword density analysis that flags stuffing long before it risks a Panda-style penalty (the tool keeps you under the 5% danger line), and readability scoring on the Gunning Fog and Flesch indexes so the rewrite stays easy to read, not just keyword-complete.
The companion workflow is built for teams. A SERP comparison mode analyzes competitor content to surface the keywords your page should include, and built-in task templates generate a complete brief for a copywriter in about a minute — replacing the manual loop of specialist checks work, writes notes, and hopes the writer follows them. Inside the online editor, interactive tips mark exactly what to rewrite, replace or delete, and once the fixes land you publish the updated content and watch behavior and Search Console positions respond. The methodology was battle-tested for two years on the team’s own projects before release, and 24/7 support covers both platform and content questions.
Pricing scales by pages checked per month: 50 pages for $29/month, 100 for $49, 200 for $69, 300 for $99, 500 for $150 and 1,000 for $300, with larger volumes up to 5,000 pages. Annual billing takes 20% off — the entry tier drops to $23/month — and you can upgrade or downgrade anytime. Individual checkers are free to try on the site.
SEO specialists cleaning up ranking blockers and marketers polishing landing pages for conversion. It is an analysis-and-repair tool, not a generator — teams wanting AI to draft the content from scratch should pair it with a writing platform.
