ChatGPT vs Claude for marketing: writing, research and workflows

ChatGPT and Claude are both strong for marketing writing. ChatGPT has more built-in features, including images, voice and agents. Claude is often preferred for long documents and a natural writing voice. The reliable way to choose is to give both the same brief and three real tasks, then count how much editing each output needs.

Where each tends to shine
