Overview

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.

Key features

- Visual key-value editor with per-field type selection
- Instant JSON preview as you type
- One-click paste directly into the active input
- History of your last 50 prompts — reuse with a single click
- Configurable floating button placement (8 positions)
- Works on any page, not just AI sites
- No account, no tracking, fully local storage

Keyboard shortcuts

- Ctrl+Shift+J — open popup
- Ctrl × 2 — open popup from any page (optional)
- Escape — close popup
- CTRL + Enter — add json text to selected text field
