vs
Claude
Claude by Anthropic
A thoughtful AI assistant built for safety, accuracy, and long-form work.

Claude is the better choice when you need more than proofreading — when you need a thinking partner that can draft content from scratch, rewrite entire sections, adjust voice and style at a structural level, or help you think through what you actually want to say. Claude approaches writing as a collaborator rather than a corrector, making it far more useful for complex writing tasks but less practical for quick in-context edits across different apps.
