Claude

Chatbots and Assistants - Pricing: freemium - Editor rating: 4.0/5 - https://claude.ai

An AI assistant by Anthropic known for careful, nuanced answers, strong writing, and handling very long documents.

Claude excels at long, complex work: it can digest entire contracts, reports, or books in one go thanks to a very large context window, and its writing style is often described as the most natural among the major assistants. It is a favorite for professional writing, analysis, and coding. The free tier gives access to a capable model, with heavier usage and the strongest models on paid plans.
