Chrome Extension Monitors AI Conversations Across ChatGPT, Claude, Gemini, and Other Platforms
A popular Chrome add-on called "Prompt Optimizer – SecondBrain" was reportedly collecting what people typed and received on several major AI chat services, even though its listing said it did not gather personal information. People who use AI tools for work, school, or personal matters may have had private conversations exposed without realizing it.
Who is at risk
Anyone who installed this Chrome add-on and used AI chat services like ChatGPT, Claude, or Gemini is most at risk, especially if they entered private, financial, work, or personal information.
What to watch for
Watch for unfamiliar browser add-ons, AI helper tools you do not remember installing, or any sign that private information was entered into AI chats while such tools were active.
What to do
Immediately remove the add-on if installed, review and delete other unnecessary browser add-ons, and avoid entering sensitive personal or work information into AI chat tools until your browser is checked.
