chatgpt-lib

Simple javascript wrapper for ChatGPT's unofficial web API

Installation

npm i chatgpt-lib

Setup & Usage

1. You will need session token for this to work.
   To obtain it:
   • go to https://chat.openai.com/chat and login
   • press F12 to open browser devtools and go to Application tab
   • find Cookies in Storage section, open them up and click on https://chat.openai.com
   • find cookie with name __Secure-next-auth.session-token and copy its value
2. Create file config.json and paste your session token as SessionToken key value:

{
  "SessionToken": "<insert-your-session-token-here>"
}

3. Here's minimal code for prompting a question to chatGPT

const cgpt = require('chatgpt-lib');
const config = require('./config');

...

const chatbot = new cgpt.ChatGPT(config);
let answer = await chatbot.ask("Hey, how are you doing today?");
console.log(answer);
answer = await chatbot.ask("Can you explain to me how quantum superposition works?");
console.log(answer);

You can also start conversation just like on the ChatGPT's web page, but in CLI mode:

// index.js contents

const cgpt = require('chatgpt-lib');
const config = require('./config');

const chatbot = new cgpt.ChatGPT(config);
chatbot.initCliConversation();

Then just run in like node index.js
