In addition to ChatGPT, Claude, and Gemini, the extensions harvest all conversations from Copilot, Perplexity, DeepSeek, Grok, and Meta AI. Koi stated the total description of the information captured contains:

Following that discovery, the safety agency uncovered seven further extensions with similar AI harvesting performance. 4 of the extensions can be found within the Chrome Net Retailer.
