Anthropic is currently developing a new beta feature for its Claude prompt composer known as Brush. The tool was first spotted within the company's development interfaces on November 12, 2026. While the feature is labeled as being under active development, the company has not provided any official documentation or public announcements regarding its specific functionality or release plans.
The introduction of Brush follows the recent addition of interactive connectors to the Claude interface, which appeared around November 10, 2026. These two updates suggest a consistent pace of front-end development at Anthropic. Observers have speculated that Brush might be related to a previous feature called Sketch, potentially serving as an evolution or a replacement for it, though this remains unconfirmed.
The name of the tool has led to theories that it may facilitate iterative or visual prompt refinement, allowing users to adjust requests in stages. However, as the feature is currently in a beta state within development builds, there is no confirmed timeline for a public rollout. Anthropic has not verified any of the circulating theories regarding the tool's purpose or its relationship to existing features.
