Release Notes
New features Control whether Bolt uses your content for model training A new Model training setting in your account settings lets you choose whether Bolt can use your projects and chats to train AI models. It's on by default, except for accounts based in the EU, UK, or Switzerland, where it's off by default. The setting applies to content you create or submit to Bolt's AI features on or after October 7, 2026. Turning it off doesn't affect your plan, and you can change it at any time. Bolt Forge keeps its own separate data-sharing terms. Learn more about the Model training setting.
