Open your notes and draw two boxes: My browser (sessions/passwords) | AI browser (clean profile). List 3 things that must never end up in the AI box (like a password manager, work SSO, or a client CRM). You're done when you've written the one rule you'll enforce this week, in 12 words or less.

Keep AI out of your real browser profile
AI-enhanced browsers inherit your logged-in sessions — prefer a separate browser profile for AI browsing tools so passwords and work tabs are not the tool surface.
Worked example
Simon Willison on AI browsers: the security and privacy issues start looking unsolvable if the browsing AI rides along in the same browser you use for banking and work. Want a model to browse the web? Give it its own separate browser profile — not the one with your password manager and open client tabs. You still own send and download decisions.
