| Custom domains | Paid plans can map a user-owned domain to a published Bool. | Users can connect a custom domain with automatic HTTPS. |
| Product | Bool is an AI app builder that turns plain-language prompts into real web apps, with a database and live preview, and one-click deployment. | FirstApp turns plain language prompts into working web applications with a frontend, backend, and database. |
| Security | Bool says it uses encryption in transit, encrypted connected-account tokens at rest, salted password hashes, per-app data isolation, scoped access controls, and audit logging. | The privacy policy lists TLS and at-rest encryption, access controls, isolated build and preview sandboxes, security headers, and audit logging among its safeguards. |
| Support | Bool lists [email protected] as its contact address and says it acknowledges vulnerability reports within three business days. | Privacy and terms inquiries can be sent to [email protected]. |
