A new report has revealed that Le Chat from Mistral AI is the most privacy-respecting generative AI, with ChatGPT and Grok close behind. The study by Incogni assessed nine popular services against 11 criteria covering data use, sharing and transparency.

Meta AI came last, flagged for poor privacy practices and extensive data sharing. According to the findings, Gemini and Copilot also performed poorly in protecting user privacy.

Incogni highlighted that several services, including ChatGPT and Grok, allow users to stop their data from being used for training. However, other providers like Meta AI, Pi AI and Gemini offered no clear way to opt-out.

The report warned that AI firms often share data with service providers, affiliates, researchers and law enforcement. Clear, readable privacy policies and opt-out tools were key for building trust.
