The verdict
For a small team that runs steady paid ads or email campaigns and argues about which version to ship, I'd pick Anyword. The score gives you a shortlist, and you then test the finalists. If you are a revenue team with repeatable steps, such as researching accounts, enriching records and drafting outreach, I'd pick Copy.ai.
If you only write copy now and then, I'd skip both. A general assistant such as ChatGPT or Claude covers occasional drafting. Two cautions. Treat the Anyword score as a model's view and check it against your own past campaigns. And only buy Copy.ai once you can write down the steps your reps follow, because a workflow tool has nothing to repeat without them.
