Claude Review (2026)
The most thoughtful AI assistant in 2026 — Sonnet 4.5 + Projects + Artifacts make Claude the writer's pick.
Claude (Anthropic) is the assistant most writing- and research-heavy testers prefer in 2026. Sonnet 4.5 is the strongest current model for long-form drafting, structured analysis over big documents, and steerable rewriting; Opus 4.5 (on Max) is the heavyweight for hard reasoning. The product layer matured fast: Projects with files and custom instructions, Artifacts for live document/code editing, Computer Use for limited UI actions, and MCP integrations for connecting to your real tools.
