Where Prompt Petal is different
- Every device you type on. Mac, Windows, Linux, iPhone, iPad and Android, with Apple Watch and Wear OS, all from one account.
- Any app. Select text, pick a petal, and the prompt lands with your selection in it, in a chat, a document or an email.
- Buttons that do things. A petal can open a link, open an app, run a Shortcut, or ask AI with your own key.
- MCP too. Claude Desktop, Cursor, VS Code and Codex can use, save and change your prompts.
When PromptBox is the better fit
If you only write prompts in a Chrome browser and like typing short codes, Prompt Box is light and quick to learn.
