What is RED?

RED sits quietly under the chat box on AI platforms and tells you — before you hit send — whether your prompt is actually good. It scores clarity, context, and specificity as you type, then rewrites weak prompts into strong ones with a single click.

No more guessing why the model gave you a mediocre answer. Fix the prompt, not the output.

Features

• Real-Time Prompt Analysis — live scoring across clarity, context richness, token efficiency, and specificity as you type
• One-Click Refinement — rewrites your prompt in one of four styles: default, concise, detailed, or code-focused
• Efficiency Metrics — see exactly how a refined prompt compares to the original
• Prompt History — revisit past prompts, their scores, and how they improved over time
• Score Trends — visual charts tracking your prompting quality over time
• Neubrutalist UI — a clean, high-contrast panel that stays out of your way until you need it

How It Works

1. Type your prompt as normal in a supported AI chat interface
2. RED analyzes it instantly, surfacing a score and specific weak points
3. Click refine to get a rewritten version — accept it, tweak it, or ignore it

Installation

RED isn't on the Chrome Web Store yet — install it manually in a few steps:

1. Download the extension from getred.vercel.app (or clone this repo)
2. Open Chrome and go to chrome://extensions
3. Toggle on Developer mode (top-right corner)
4. Click Load unpacked
5. Select the RED project folder
6. Visit a supported AI chat site — the panel will appear automatically under the input box

Tech Stack

• Manifest V3 Chrome Extension — Shadow DOM injection, service worker architecture
• Vanilla JavaScript — no framework overhead, fast to load
• Chart.js — score trend visualizations
• Vitest — 244 tests across 9 test suites covering analysis, auth flows, and UI components

Running Tests

npm install
npx vitest run

All 244 tests should pass across the 9 test suites.
