Claude
Claude leads every major public benchmark in 2026 and is the strongest all-around AI assistant available. Its edge is in reasoning, long-document analysis, and writing quality - tasks where the difference between a good and a great response is obvious. The free tier is generous. Claude Pro adds extended context, priority access, and integrations with Google Docs and Gmail. If you only try one AI assistant, try this one.
