Why I built it

Anyone who uses AI tools seriously ends up with prompts scattered across notes apps, docs, and chat history. Prompt Box gives them one home and makes them reachable from the place you actually need them: the text field you are typing in. Save a prompt once, give it a trigger like /summarize, and it expands anywhere in Chrome, whether that is ChatGPT, Gmail, Notion, or Slack.

What it does

  • Text expansion: type a trigger keyword and watch it expand to full text
  • Right-click any selected text to save it as a prompt or snippet
  • One-click copy for any saved prompt, in ChatGPT, Gmail, Notion, or Slack
  • Import and export your prompt library

Does Prompt Box work outside of ChatGPT?
Yes. Text expansion works in any text field in Chrome, including Gmail, Notion, Slack, Google Docs, and every AI chat interface, not just ChatGPT.
