Is this a scandal?
No longer — the story has resolved. Noise 5/100, cooling down, across 0 sources.

Noise 5/100 — louder than 97% of tracked AI controversies.
Why it matters
This highlights a critical security gap where third-party browser tools bypass the privacy guarantees of AI providers, potentially exposing sensitive corporate and personal data to brokers.
Key points
- Users report receiving hyper-targeted ads based solely on prompts entered into ChatGPT and Claude.
- Extensions with 'On all sites' permissions can access the DOM to read text entered into AI prompt lines in real-time.
- The controversy highlights a discrepancy between AI provider privacy policies and the vulnerabilities introduced by the browser ecosystem.
- Security advocates recommend restricting extension access to 'specific sites' or removing non-essential plugins entirely.
- Evidence suggests some 'free' extensions are specifically designed to build large user bases for the purpose of data harvesting.
The story
Concerns regarding data privacy in the AI sector have intensified following reports that common browser extensions are harvesting user prompts from platforms like ChatGPT. A user report detailed receiving highly targeted advertisements for obscure topics previously only discussed within an LLM interface, suggesting that extensions with 'read and change all your data' permissions are monitoring Document Object Model (DOM) changes to scrape input fields. While AI companies like OpenAI maintain strict data privacy policies regarding third-party ad sales, the broad permissions granted to helper tools and 'dark mode' plugins create a side-channel for data brokers. Security analysts warn that even 'legitimate' extensions may be monetizing user interactions by auctioning captured metadata and prompt content to ad-tech firms.
Who's involved
Claims browser extensions are exploiting broad DOM access to scrape and sell private AI prompt data to ad-tech brokers.
Identified as an extension requiring excessive permissions that cannot be restricted to specific sites.
Maintains that they do not sell user data to advertisers, though they are not responsible for third-party browser modifications.
