Harmony SEO Content Grader
Albuquerque, New Mexico, United States
What it is
Harmony SEO Content Grader reviews a draft for SEO and returns a score out of 100, a grade from A+ to F, missing terms, and notes about structure. To use it, enter a target keyword, paste a draft of up to 8,000 characters, and select “Grade my draft.” Its evaluation covers keyword use, term coverage, structure, and depth, then offers concrete fixes and terms to consider adding. The tool runs in a browser, and its page says text is not uploaded or stored. No account is required. The free version allows 3 grades per day. Tools Pro removes that daily limit and includes unlimited grammar and plagiarism checks, unlimited generators, readability and AI readability scores, and BookBlurb AI descriptions. Tools Pro costs $4.99/mo and can be canceled anytime. The product is from Harmony Publishing, based in Albuquerque, New Mexico. The site describes its browser tools as intended for indie authors and self-publishers. This grader focuses on topic coverage analysis; content briefs and CMS publishing are not included.
