JSON Prompter

About

Stop hand-typing JSON into AI prompts!
JSON Prompter lets you build structured key-value payloads visually and inject them into any AI chat in seconds — no curly braces, no copy-paste, no mistakes.

  How it works

  Open the popup with Ctrl+Shift+J (or double-tap Ctrl), add your key-value pairs, pick the
   type for each field (string, number, boolean, or null), and hit Paste — the JSON lands
  in whichever text field you were just using.

  - Instant JSON preview as you type
  - One-click paste directly into the active input
