ChatGPT Prompt Checker

A Chrome extension designed to ensure your ChatGPT conversations stay on topic using AI-powered prompt verification.

Features

Context Enforcement: Set a specific keyword or topic (e.g., "physics", "finance") in the extension settings.
AI Verification: Before sending a prompt to ChatGPT, the extension securely checks it against your specified topic using a backend AI worker.
Smart Interception: If your prompt strays off-topic, the extension elegantly halts the submission and presents a custom warning modal explaining why the AI flagged it.
Session Bypass: Choose to bypass the warning and send the prompt anyway, which automatically approves all subsequent prompts for that specific ChatGPT tab session.
Seamless Integration: Runs silently in the background and integrates perfectly with the ChatGPT web interface without injecting clunky UI widgets into the page.

Technical Architecture

Manifest V3: Built using the modern Chrome Extension Manifest V3 standard.
Content Script (content.js): Injected into chatgpt.com to safely intercept keyboard and mouse submission events. Includes logic to bypass React's synthetic event pooling.
Service Worker (background.js): Handles secure communication with the backend validation API, preventing CORS and Content Security Policy (CSP) issues on the host page.
Backend: Relies on a custom Cloudflare Worker endpoint (https://worker-1.athiyagu6.workers.dev/api/check) to perform the actual AI verification.

Privacy Policy

This extension requires a connection to an external rendering worker to verify prompt context. A unique, anonymous UUID is generated upon installation to manage request limits, but no personal data or ChatGPT conversation history is stored persistently by the extension or the backend verification service.
