ChatGPT Writer and Sudowrite serve entirely different buyers.

Pick ChatGPT Writer if you handle high email volume and need AI-drafted replies across Gmail, LinkedIn, and other web platforms without leaving your tab.
Pick Sudowrite if you're a novelist, screenwriter, or fiction author who needs GPT-4 assistance with character consistency, dialogue, and scene expansion.
