Questions about copy grading
What does this copy grading tool check?
Hook strength, show vs. tell discipline, section discipline, specificity, CTA clarity and persuasion structure, plus readability metrics like reading grade and passive voice.
Do I need an account to grade copy?
No. You get free credits without signing up, and more credits when you create an account.
Is my copy good? How do I know?
Paste it in and Whetstone names the specific failures: where the hook stalls, where you tell instead of show, where the CTA gets vague. You get a score per category and an overall grade.
Does a high score mean the copy will convert?
No. Whetstone grades adherence to direct-response writing principles, not real-world results. Proven, profitable copy can still show gaps here.
How do I actually use it?
Paste or upload your copy, name the business, add context like format, audience and goal, then press Grade It. There's a full step by step walkthrough with diagrams in Settings, under How to use.
