nitpic — browser feedback for AI coding agents

About

nitpic connects your browser to your AI coding agent. Click anything on any page, say what's wrong, and watch it get fixed.

HOW IT WORKS

1. Turn on feedback mode and click any element on any page — localhost or production
2. Type what should change ("right-align this button", "too much padding on mobile")
3. Hit send — your comment, a cropped screenshot, and the element's HTML land inside your running Claude Code session as if you typed them there, and Claude gets to work

Built for designers, developers, and vibe coders who review their app in the browser but fix it in the terminal.

FEATURES

• Point at the problem — hover-highlight any element or drag-select a region; nitpic captures the CSS selector, screenshot, and HTML for you
• Instant delivery — feedback lands in your terminal within a second (tmux and iTerm2 get true keystroke injection; other terminals deliver when Claude finishes its current response)
• You choose the session — type /nitpic in whichever Claude Code session should listen; run it elsewhere to move the connection
• Batch reviews — collect comments across pages and tabs, then send them as one message, grouped by page
• Floating panel — draggable, collapsible, never squeezes your viewport or triggers responsive breakpoints
• Zero-friction setup — pairing happens automatically; you never copy a code or touch a config file

PRIVACY

Everything is local: no accounts, no servers, no telemetry. The extension talks only to the nitpic companion on your own machine (127.0.0.1), collects no data, and phones no home.

REQUIREMENTS

Requires the free nitpic plugin for Claude Code — the extension's welcome page walks you through the two-minute setup with a live checklist.

Works with Claude Code today. Cursor, OpenAI Codex, and Gemini CLI support are on the roadmap.
