How it works

This project uses the ChatGPT API and Vercel Edge functions. It takes a template for each action or command type, and based on the inputs and mission, it sends ChatGPT the commands to get the required results. The "command" field in each template is most important to tell ChatGPT what to do. In addition, you can add different input types for each template if you wish to use additional parameters. More template can be added to the TEMPLATES list.

Add your own OpenAI API key and have your own Jema.ai

In order to work locally or deploy this project to Vercel, you need to set your OPENAI_API_KEY to use ChatGPT3 API. Once added , this should work out of the box.

Running Locally

This project is built with Next.js and TailwindCSS, so you can deploy it directly to Vercel.

After cloning the repo, go to OpenAI to make an account and put your API key in a file called .env.local(OPENAI_API_KEY) Then, run the application in the command line and it will be available at http://localhost:3000.

npm install

yarn dev

Changing ChatGPT prompts and requests

You can fine tune ChatGPT to your needs, give it any mission that you wish it to complete. The basic message structure is as follows:

const generateOutputHandler = async (template: Template, inputsData: { [key: string]: string }) => {
    const instruction = createInstruction(template.inputs, inputsData);
    const mainGoal = template.description;

    const messages = [
        { role: "system", content: "You are a helpful assistant." },
        { role: "user", content: `Your task is: "${mainGoal}".\n\nHere are the details:\n${instruction}. 
            Please suggest 3 outputs. number them 1,2,3` },
    ];

    try {
        const response: any = await openai.createChatCompletion({
            model: "gpt-3.5-turbo",
            // @ts-ignore
            messages: messages,
            temperature: 1,
        });

        const reply = response?.data?.choices[0].message.content;
        setOutput(reply || '');

    } catch (error) {
        console.log(error)
    }
};
