Claude by Anthropic
by Anthropic PBC
About this app
Claude is Anthropic's AI assistant, and the strongest competitor to ChatGPT for users who care deeply about writing quality, reasoning depth, and intellectual honesty. Anthropic was founded by former OpenAI researchers with a specific focus on AI safety, and that philosophy is reflected in how Claude behaves: it is more careful, more nuanced, and more willing to say "I'm not sure" than most AI assistants. The app gives free users access to Claude Sonnet — a highly capable model — with Claude Opus reserved for Pro subscribers. What distinguishes Claude most is its context window: up to 200,000 tokens, meaning you can paste in an entire research paper, a long codebase, or a full novel manuscript and ask Claude to analyze, summarize, or work with it all at once. For writers, analysts, lawyers, and developers dealing with long documents, this is a significant practical advantage over competitors.
Features
- →200K Token Context Window — Process entire books, legal contracts, or large codebases in a single conversation. Claude holds far more context than most AI assistants without losing coherence.
- →Best-in-Class Writing Quality — Claude's prose is noticeably more natural and less generic than competitors. Ideal for drafting emails, essays, reports, cover letters, and creative writing.
- →Document & File Analysis — Upload PDFs, Word documents, images, and data files. Ask Claude to extract key points, compare sections, identify inconsistencies, or rewrite in a different tone.
- →Calibrated Honesty — Claude flags uncertainty, acknowledges limitations, and refuses to fabricate citations — making it more trustworthy for research and fact-sensitive work.
Final take
Claude is the best AI assistant for anyone who writes for a living, works with long documents, or wants an AI that reasons carefully rather than just confidently. Its writing output is consistently more polished than ChatGPT's, and the long context window is genuinely transformative for document-heavy workflows. The main limitations are no image generation and a smaller integration ecosystem compared to OpenAI. But for pure thinking and writing quality, Claude is the one to beat.
