本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
ChatGPT stands out with Conversational AI writing and Custom GPTs. Copy.ai counters with 90+ copywriting templates and Workflow automations.
ChatGPT's Achilles heel: not purpose-built for marketing — no brand voice, no templates, no team workflow. you have to prompt-engineer everything yourself. Copy.ai's: output quality is inconsistent — great for first drafts but you'll spend time editing, especially for long-form. Pick whichever weakness you can live with.
