In the midst ot a huge layoff, many employees are livid that Meta will use them to train their replacements. Meanwhile, Meta assured them that the data will never be used for performance reviews or personal surveillance. ? Patrick Wood, Editor.

Google, LinkedIn and Wikipedia are among hundreds of websites and apps where Meta plans to capture employee keystrokes and mouse clicks as part of a project to train its artificial intelligence models, according to internal messages viewed by CNBC.

A new employee tracking tool, dubbed Model Capability Initiative (MCI), allows Meta to observe and collect data from staffers' actions on their work computers, Reuters first reported on Tuesday. The list of sites being tracked, which also includes Microsoft's GitHub, Salesforce's Slack and Atlassian, has not been previously reported.

Meta properties like Threads and Manus are also on the list, which is still in flux and originally included AI apps like OpenAI's ChatGPT and Anthropic's Claude.

The list of third-party sites and services the MCI tool is tracking was widely circulated internally and discussed on chat boards after a member of the Meta Superintelligence Labs, or MSL, sent a memo intended to assuage concerns about worker surveillance and privacy. CNBC viewed the memo.
