$4.99

PRIVATE BY DESIGN
PromptFast does not require an account and does not operate servers for your prompt library. Your prompts stay on your devices and, when enabled, sync through iCloud. API keys are stored in the device Keychain and prompt runs go directly from your device to the provider you choose.
Built for professionals who want their prompt workflows to be fast, reusable, organized, and under their control.
