Harmony SEO Content Grader

What Harmony SEO Content Grader is

Harmony SEO Content Grader reviews a draft for SEO and returns a score out of 100, an A+ to F grade, missing terms, and structure notes. To use it, enter a target keyword, paste up to 8,000 characters, and select “Grade my draft.” Its evaluation covers keyword use, term coverage, structure, and depth, with concrete fixes and suggestions for terms to include. The tool runs in the browser, and its page says text is not uploaded or stored. No account is required. The free plan allows 3 grades per day. Tools Pro removes that limit and includes unlimited grammar and plagiarism checks, unlimited generators, readability and AI readability scores, and BookBlurb AI descriptions. Tools Pro costs $4.99 a month, and users can cancel anytime. The tool is made by Harmony Publishing, based in Albuquerque, New Mexico; the site describes its browser tools as intended for indie authors and self-publishers. Its listed scope is topic coverage analysis; content briefs and CMS publishing are not included.
