Does Writesonic train on my data?

Two different things often get mixed up. Used to train models means your content helps build or improve the AI itself, so it can shape what the model produces later. Used to provide the feature means your content is processed to give you the answer, summary or suggestion you asked for, which any AI feature has to do. PolicyPeek's badge is about the first one only.

In the UK: if personal data is involved, the UK GDPR applies to how it's used, including for AI.

The Information Commissioner's Office publishes guidance on AI and data protection.
