What Harmony SEO Content Grader is
Harmony SEO Content Grader reviews a draft against a target keyword and returns an SEO score out of 100, a letter grade from A+ to F, missing terms, and structure notes. To use it, enter a keyword, paste a draft of up to 8,000 characters, and request a grade. Its evaluation covers keyword use, term coverage, structure, and depth, with specific fixes and suggestions for terms to incorporate. The browser-based tool requires no account, and the page says draft text is neither uploaded nor stored. Free use is limited to 3 grades per day. The Tools Pro plan costs $4.99 a month and removes the grading limit; it also includes unlimited grammar and plagiarism checks, unlimited generators, readability and AI readability scores, and BookBlurb AI descriptions. Tools Pro can be cancelled anytime. The tool is a Harmony Publishing product, and the site describes its browser tools as intended for indie authors and self-publishers.
