Design feedback for AI coding agents

Select any element on a live page, describe what should change, and export structured prompts that AI agents can act on immediately.

Demo coming soon

How it works

1

Pick an element

Click any element on a live page. Nitpick captures its CSS, box model, HTML structure, and a screenshot automatically.

2

Describe the change

Write what should be different — spacing, color, layout, behavior — and tag it with a category for smarter prompts.

3

Export or create a ticket

Copy a structured AI prompt to your clipboard, or push directly to Linear. Jira and GitHub Issues coming soon.

4

AI implements the fix

Paste into Claude Code, Codex CLI, or any AI agent. It gets full context — selectors, computed styles, box model, and your instructions.

Features

🎯

Visual context capture

Every annotation includes computed CSS, box model dimensions, an HTML snapshot, and a screenshot — everything an AI agent needs to make the fix.

🤖

Structured AI prompts

Exports optimized prompts for Claude Code, Codex CLI, and other AI agents. Includes selectors, styles, and clear instructions.

🎫

Ticket integration

Push nits directly to Linear with full context attached. Jira and GitHub Issues support coming soon.

🔌

Nitpick API endpoint

Sites can expose /.well-known/nitpick.json with component mappings and design tokens. Auto-discovered by the extension for richer prompts.

Free forever. Cloud when you need it.

Everything that runs locally stays free. Cloud adds collaboration and convenience.
