Read the caveats
Several of these promises have limits written into the policy itself. Kagi says it uses providers that don’t train “whenever possible”. Sourcegraph’s clause covers Cody Enterprise and Cody Pro teams. Zoom’s promise leaves out usage data and de-identified aggregates. Moises and Pictory allow training where you have expressly agreed. Open each tool page to read the full wording.
What’s different for UK users?
PolicyPeek gives each tool one verdict, whatever country you’re in. The live site has one UK-specific note: for Bolt.new (Trains by default, you can opt out), “Accounts in the EEA, UK and Switzerland don’t need to opt out.” (All tools)
PolicyPeek also explains why an opt-out doesn’t get the green badge: “GDPR generally expects opt-in consent, not an opt-out you have to go find in a settings page or a support form.” It’s not legal advice or a finding about any law. (Methodology)
Popular tools that do train by default
ChatGPT, Claude (consumer plans), Cursor, Grammarly and Perplexity AI are Trains by default, you can opt out. Perplexity’s help centre says: “For Free, Perplexity Pro and Perplexity Max users, AI Data Retention is enabled by default. However, these users can control whether their data is used for AI model training.” (source) DeepL (rated on its free tier) is Trains on your data, no opt-out. (All tools) Gemini has no product verdict yet, because only a company-wide policy was found.
How PolicyPeek decides
An AI model extracts the facts from the policy, then fixed rules decide the badge. Results the rules aren’t sure about are held for a person to look at; not every verdict is reviewed by a person. Each tool page links the exact policy used and the date it was checked. (Methodology)
