Anthropic is developing a beta feature called Brush for the prompt composer in Claude’s interface. It was spotted in development interfaces on November 12, 2026, but the company has made no official announcement or released public documentation. Any connection to the earlier Sketch feature, including a possible replacement, remains speculative. Brush may allow visual or step-by-step prompt refinement instead of complete rewriting, but Anthropic has not confirmed this theory. No launch date or rollout plan is known, so the feature has no immediate impact for users.
