What is Claude (Sonnet 4.6)?
Claude, developed by Anthropic, is the go-to AI for long-form writing and analysis. Its defining feature is the 200K token context window — you can drop in an entire book manuscript, a full research paper, or a complete codebase, and Claude will process it all at once.
Claude's writing style is widely considered the most natural and nuanced among major AI assistants. It handles complex reasoning, logical argumentation, and multi-document synthesis with remarkable depth. For academic writers, it's particularly strong at literature reviews, methodology sections, and maintaining coherent arguments across long documents.
The Projects feature lets you create persistent workspaces with custom instructions and knowledge files, making Claude a powerful research and writing companion.
