Modify — AI Coding Visual CSS Editor for Designers and Developers

A visual CSS editor for designers and developers. Edit your live site, then your AI agent writes each change into real source code.

Design with your agent, not against it. Modify is a visual CSS editor for designers and developers. Adjust styles, layout, spacing, and copy directly on your real, live site — no DevTools, no guessing. Every change is captured as an exact CSS delta, so your AI coding agent writes it straight into your real source code. Telling an AI agent to "move the button a little to the left" turns into a guessing game: wrong element, wrong amount, three retries. Modify replaces that with the exact selector and before-and-after values, so the change lands in one shot. HOW IT WORKS 1. Edit the live page — like Figma. Select any element on any website: drag, resize, recolor, edit text, tune spacing. A design panel shows exact values as you work. 2. Every change is captured — exactly. Modify records each edit as a structured delta: CSS selector, property, old value, new value, plus page context. 3. Copy one prompt. Your agent nails it. Click "Copy AI Prompt" and paste into your tool. It edits the right file with the exact values — no pixel guessing, no retry loops. WORKS WITH EVERY AI CODING TOOL The exported prompt is plain structured text, so there is nothing to integrate: • VS Code + GitHub Copilot (Chat and Edits) • Claude Code, Gemini CLI, Codex CLI, opencode, aider and other terminal agents • Or hand it to a teammate as an implementation brief Built for developers whose editor has no visual layer: if you write frontend in VS Code or drive a CLI agent from the terminal, Modify is the missing browser side of your workflow. FEATURES • Figma-style visual editing on any live page — position, size, colors, typography, spacing, text • AI Prompt panel: all changes collected with before/after values, ready to copy • Comment pins: annotate elements with instructions ("use a more suitable icon here") that export with the prompt • Works with Tailwind, React, Vue, plain CSS — your agent decides how to express the change in your codebase • HTML to Figma capture • Local-first: edits and prompts are generated in your browser; your page content stays with you FREE TO START Free plan includes prompt generations and Figma captures to try the full workflow.
