Anthropic updated its Chrome extension on August 12, 2026 to let the Claude side panel bot save chat histories. Users can continue conversations on Claude’s desktop, web, or mobile apps. The Claude Cowork extension, which adds a side panel to Chrome, was released earlier for Max and Team subscribers. The updated version saves chat sessions to the user’s history, enabling continuation outside the browser. Pro users will receive the update over the coming weeks. The feature expands Claude’s cross‑platform functionality as the company rolls out additional tools for paid tiers.
