Claude handles long documents better than anything else at the Pro tier. Feed it a 50-page contract, a research paper, or a messy transcript and it extracts what you need with minimal hallucination. That long-context reliability is where it earns its place.
The writing quality is also consistently better for anything that needs to sound like a human wrote it: emails, articles, client-facing copy. The free tier is functional but you will hit the daily cap if you use it seriously. Pro at $20/mo is a fair price. The Max tiers exist for people who run into the per-session limits on heavy workdays, but most users never need them.
