                        * Control browser actions from Claude Desktop: Start a task in Claude Desktop and let it handle work in the browser without switching windows.

                        * Record a workflow: Teach Claude your workflow by recording the steps, and Claude learns to repeat them. Useful for repetitive browser tasks you want to delegate.

                    Context window compaction

                    We’ve changed our context window functionality to enable infinite-length conversations (with some exceptions) and significantly reduce length limit errors by summarizing earlier messages when a chat approaches its context limit.

                        * Scheduled tasks: Set recurring browser tasks to run automatically on your schedule. Set it once and Claude handles it from there.

                        * Follow a plan: Approve Claude's plan, then let it execute the entire workflow independently within those approved boundaries, without asking for permission until it's done.

                        * Model selection: Choose between Haiku 4.5 for speed, Sonnet 4.5 for complex tasks, or Opus 4.5 for maximum reasoning power—switch anytime based on what you need.

                        * Powered by Haiku 4.5: Claude in Chrome now defaults to Haiku 4.5 so it’s a faster, more responsive experience. You can always switch back to Sonnet 4.5.

                        * Claude handles image uploads for you: Give Claude an image and tell it where to upload, whether it’s an expense report, form attachment, or a picture upload.

                        * Show Claude exactly what you mean: Take a screenshot or drag to highlight specific parts of your screen. Point Claude to the exact button, field, or detail—much faster than describing complex layouts in words.

                        * Work across multiple tabs: Claude can now juggle multiple browser tabs at once. Just drag tabs into Claude's tab group and it can see and work across all of them simultaneously—no more jumping back and forth to gather information before taking action.

                        * Smarter on the sites you use every day: Claude now understands how to navigate Slack, Google Calendar, Gmail, Google Docs, and GitHub without you having to direct every click. Ask Claude to "schedule a meeting" or "update the doc" and it knows what to do—no need to walk it through every step. We’re continuing to improve Claude’s understanding of other popular sites.

                        * Get notified when Claude needs you: Turn on notifications and Claude will ping you when it needs your permission or when a task is complete. Now you can switch to other work while Claude handles things in the background.

                        * Show Claude exactly what you mean: Upload images or take screenshots of specific screen areas to give Claude precise visual context. Much faster than describing what you're looking at.
