FakeGPT

Fake your own AI chatbot with just Javascript and HTML.

A very basic and German configuration is deployed here. Try the question: "Ist eine ethische Nutzung von Generative AI möglich?"

Prerequisite

• Installation of nodejs version >= 23

Install and Run

npm install

npm start

Then move your browser to http://localhost:3000.

Run with Docker

docker build -t fakegpt .
docker run -it --rm -p 3000:3000 fakegpt:latest

For overriding answers and/or configuration add the respective volume mounts:

   -v /path/to/your/configuration.js:/app/public/configuration.js
   -v /path/to/your/answers.js:/app/public/answers.js

Configuration of Texts

The texts that are displayed on the page are configured in file configuration.js.

Configuration of Answers

The answering logic resides in file answering.js whereas the actual answer texts are in answers.js. You can either just modify the answer texts according to your own needs or change the whole answering mechanism.

The simplest way is to modify the const myAnswers object in file answering.js; it can have multiple properties.

Therein, a property key can represent either

• a regular expression within square brackets [...]
• or a string to match some part of the user input - ignoring upper and lower case.

A property is an array of answer segments. Each segment can be one of:

• a literal html string that is rendered as is
• a function that takes the regular expression match array as argument and returns an html string
• a number that will be interpreted as "thinking time" in milliseconds

A few examples:

const myAnswers = {
        "hello": [
            "Hello! How can I help you?",
            "Maybe you want to ask me something?"
        ]
}

This will answer to any input that contains the word "hello" with the two given lines.

const myAnswers = {
    [/hello|hallo/]: function (helloMatch) {
        var query = helloMatch[0];
        if (query.toLowerCase().includes("hallo")) {
            return [
                "<p>Hallo! Wie kann ich dir helfen?</p>",
                "<p>Vermute ich richtig, dass du Deutsch verstehst?</p>"
            ];
        }
        return ["Hello! How can I help you?"];
    }
}

This will answer to any input that contains the word "hello" or "hallo". If the input contains "hallo", the answer will be in German.

But you can also use the captured groupings of a regular expression:

const myAnswers = {
  [/who is ([a-zA-Z\s]+)\\?|$/i]: function (whoIsMatch) {
    const name = whoIsMatch[1];
    return [
      `<p>I only know important people. 
       <span style="font-weight: bold">${name}</span> is none of them!</p>`
    ]
  }
}

Answer does not match

If none of the key expressions match, the function defaultAnswer will be invoked and its result used as answer. For example:

export default function defaultAnswer(query) {
    return [
        `<p>I do not understand "${query}". What do you expect me to do?</p>`
    ]
}
