Calling Your Private GPTs from ChatGPT with 50 Lines of Python Code

This tutorial demonstrates how to programmatically call your private GPTs created in ChatGPT using approximately 50 lines of Python code, without additional API costs.

Prerequisites:

A ChatGPT Plus membership account

Python 3.7+ installed locally

Network access to ChatGPT

Required Libraries:

Install pyperclip and playwright:

pip install pyperclip

pip install playwright && playwright install

Key Concepts:

The solution uses Playwright (a Microsoft-developed automation framework) to control the browser and pyperclip to access clipboard data. The approach leverages persistent browser context to maintain login sessions without repeated authentication.

Code Structure:

1. Persistent Login Setup:

import time

import pyperclip

from playwright.sync_api import sync_playwright

def login():

with sync_playwright() as p:

context = p.firefox.launch_persistent_context(

'./gpts_firefox_dir',

headless=False,

slow_mo=500

)

page = context.pages[0]

page.goto('https://chat.openai.com/')

login()

2. Query GPTs Implementation:

...

def query():

with sync_playwright() as p:

browser = p.firefox.launch_persistent_context(

'./gpts_firefox_dir',

headless=False,

slow_mo=500

)

page = browser.pages[0]

# This is private, replace with your own GPTs URL

page.goto('https://chat.openai.com/g/g-OitD1zCwT-story-weaver')

time.sleep(2)

page.query_selector("#prompt-textarea").fill("Tell me, what is your knowledge base cutoff date?")

page.wait_for_selector('button[data-testid="send-button"]').click()

time.sleep(10)

copy_button_selector = 'button.text-xs.dark\:hover\:text-gray-200'

copy_buttons = page.query_selector_all(copy_button_selector)

(copy_buttons[len(copy_buttons)-1]).click()

time.sleep(1)

clipboard_content = pyperclip.paste()

# Print clipboard content

print(clipboard_content)

str = 'y'

while str == 'y':

str = input('Waiting, continue waiting? y/n.\n\nPlease input: ')  # Control sleep time

page.close()

browser.close()

query()

Important Notes:

The author recommends using Firefox instead of Chromium for web robot development

Use playwright codegen tool to generate element selectors for complex pages

Replace the GPTs URL with your own created GPTs address

This method avoids additional API calling fees by leveraging the Plus membership
