Best AI Chat Assistants

General-purpose AI assistants that answer questions, draft text, write code, and search the web from one chat box. Nearly everyone uses one now, so the real differences are context length, real-time knowledge, citations, and where the assistant lives. The strongest options pair a frontier model with either verifiable sources or deep hooks into the tools you already work in.
