Write, organize, and improve your prompts in one place — then auto-inject them into any AI chat with a single click. No copy-paste, no lost prompts.
No sign-up required — your prompts stay in your browser until you choose to sync.
The PromptEditor Chrome extension injects your saved prompts straight into the AI you're already using. Pick a prompt, click once, and it lands in the chat box — fully formatted, every time.

Organize at scale with folders and tags, then jump anywhere with the command palette and global search.
Parameterize prompts with variables, switch between profiles, and chain prompts into reusable workflows.
Create a one-click share link for any prompt, or import prompt text straight from a raw URL.
