storybook-addon-scratchpad

A lightweight Storybook addon for capturing component feedback during design reviews. Take notes on each story, then copy everything as markdown to paste into your workflow.

Why This Exists

When doing component design reviews—especially with AI coding agents—I needed a way to jot down feedback as I clicked through stories, then paste all my notes back into chat for fixes. Every existing solution required external services, accounts, or backend setup.

This addon is intentionally lo-fi: notes save to localStorage, export as markdown, and that's it. No hosting, no accounts, no complexity. Just a scratchpad that lives in your Storybook.

The workflow:

1. Review components in Storybook, noting issues as you go
2. Click "Copy All" to get markdown-formatted feedback
3. Paste into your AI agent, issue tracker, or team chat
4. Fixes get made, repeat

Features

• Per-story notes - Each story gets its own scratchpad
• Auto-save - Notes save automatically as you type (500ms debounce)
• localStorage persistence - No backend required, notes persist in browser
• Markdown export - Copy all notes formatted as markdown with one click
• Storybook theming - Matches your Storybook theme (light/dark)

Installation

npm install storybook-addon-scratchpad

Usage

Add the addon to your .storybook/main.js (or .storybook/main.ts):

export default {
  addons: [
    // ... other addons
    'storybook-addon-scratchpad',
  ],
};

That's it! A "Scratchpad" panel will appear in your Storybook's addon panel.

How It Works

1. Select any story in Storybook
2. Open the "Scratchpad" panel in the addon panel area
3. Type your notes - they auto-save as you type
4. Navigate to other stories - each has its own notes
5. Click "Copy All" to export all notes as markdown

Panel Actions

Action	Description
Clear	Remove notes for the current story
Clear All	Remove all notes (with confirmation)
Copy All	Copy all notes as markdown to clipboard

Exported Markdown Format

When you click "Copy All", notes are formatted for easy pasting:

## Storybook Feedback

### components-button--primary
- hover state is missing

Use Cases
