- **System Zero launch** System Zero makes text decisions with boolean, choice and score questions. Existing users and people with a current invitation can sign in and manage keys under API keys. For more information, see [Quickstart](https://www.rightnowai.co/docs/system-zero/quickstart).
- **Playground launch** Run a System Zero decision in Playground without pasting an API key. Open an example in your workspace's Playground, edit the state and questions, then run it. For more information, see [Playground](https://www.rightnowai.co/docs/system-zero/playground).
- **Billing and credits status** The API is not charged, and the console takes no payment while billing is closed. Workspace usage limits still apply. For more information, see [Billing and credits](https://www.rightnowai.co/docs/system-zero/billing-and-credits).
