ChatGPT Pro Automation

Send prompts to ChatGPT (including project GPTs) via Playwriter and get responses back. Connects to your existing Chrome session - no need to quit Chrome or manage cookies.

When to use

• Cross-validate complex reasoning with a second model
• Leverage GPT-5.2 Pro's extended thinking for research tasks
• Query a ChatGPT Project that has custom instructions/files

Requirements

• Chrome with Playwriter extension installed and activated on at least one tab
• User must be logged into ChatGPT in Chrome
• Dependencies: playwright-core, playwriter

Configuration

Set CHATGPT_ORACLE_URL to use a custom default URL (e.g., a ChatGPT Project).

Option 1: .env file in repo root

# .env
CHATGPT_ORACLE_URL="https://chatgpt.com/g/g-p-.../project"

Option 2: Environment variable

export CHATGPT_ORACLE_URL="https://chatgpt.com/g/g-p-.../project"

If not set, defaults to https://chatgpt.com/.

Usage

As a module

import { askChatGPT } from './chatgpt-automation.js';

const result = await askChatGPT({
  prompt: 'Your question here',
  model: 'pro'
});

console.log(result.response);

Parameters

Return value

  success: true,       // Did it work?

}

Models

• auto: ChatGPT decides how long to think
• instant: Fast responses
• thinking: Extended thinking for complex questions
• pro: Research-grade intelligence (can take 10+ minutes)

Examples

Simple question

const result = await askChatGPT({
  prompt: 'What are the key differences between REST and GraphQL?',
  model: 'instant'
});

With a project GPT

const result = await askChatGPT({
  url: 'https://chatgpt.com/g/g-p-69590661701c8191958b62e91c543dfb/project',
  prompt: 'Review this architecture decision',
  model: 'pro',
  timeout: 1800000  // 30 min for complex analysis
});

With file attachments

import fs from 'node:fs';

const result = await askChatGPT({
  prompt: 'Find bugs in this code',
  files: [
    { path: 'src/main.py', content: fs.readFileSync('src/main.py', 'utf-8') }
  ]
});

Long-running requests

GPT-5.2 Pro can take 10+ minutes for complex tasks. For long requests, run as a background task in Claude Code rather than blocking.

Troubleshooting

• "Extension not running": Click the Playwriter extension icon in Chrome on any tab
• Model not switching: ChatGPT may have changed their UI; check data-testid values
• Empty response: Increase timeout or check if ChatGPT is rate-limiting
