Claude, published by Anthropic, has a solid sidebar extension and an agent that can execute tasks for you. Clear publisher. Clear branding. Legit.
But when you search for ChatGPT or Gemini, the store is full of copycats and pretenders using similar names and icons.
Why this is dangerous
AI sidebars often get permission to:
- Read and change data on all websites
- Click, type, and submit forms on your behalf
In the wrong hands, that means:
- Account changes you didnât approve
- Transactions you didnât initiate
- Accounts literally being emptied.
This goes for every extention, but with AI extentions that are designed to read, write and act on your your behalve it's even more dangerous and likely to be exploited.
What to check (every time)
- Publisher name
- Publisher email & domain (must match the real company)
- Permissions (global access â casual)
The Chrome Web Store is not a trust guarantee.
If the publisher doesnât clearly match the brand, donât install it!
