Custom Prompt for the chat bot. (Using the PromptId)

This starter uses https://promptable.ai to fetch it's prompts.

If you'd like to use your own prompts on Promptable, you can paste in a prompt id. (You can get your prompt id on the deployments tab)

NOTE: To get the chat bot to work correctly, you'll have to add a {input} for the chat history like this.

The bot will inject the chat history into a variable called {input} in your prompt.

Example: (This is the default prompt btw)

Below is a conversation between a knowledgable, helpful, and witty AI assistant and a user, who has some questions about a topic.
The AI assistant is able to answer the user's questions and provide additional information about the topic. The AI assistant is able to
keep the conversation focused on the topic and provide relevant information to the user. The closer the AI agent can get to
answering the user's questions, the more helpful the AI agent will be to the user.

CHAT HISTORY:
{input}

T3 Stack

This is a T3 Stack project bootstrapped with create-t3-app.

What's next? How do I make an app with this?

We try to keep this project as simple as possible, so you can start with just the scaffolding we set up for you, and add additional things later when they become necessary.

If you are not familiar with the different technologies used in this project, please refer to the respective docs. If you still are in the wind, please join our Discord and ask for help.

Learn More

To learn more about the T3 Stack, take a look at the following resources:

You can check out the create-t3-app GitHub repository — your feedback and contributions are welcome!

How do I deploy this?

Follow our deployment guides for Vercel and Docker for more information.

SMS Support with Twilio (Optional)

Twilio SMS chatbot using GPT3. Based on this tutorial.

Things you will need

Create a Twilio Account / Phone Number

Based on this tutorial. After your account is created, use this command to create a phone number that can receive SMS messages:

twilio phone-numbers:update PHONE_NUMBER --sms-url https://RANDOM_STRING.ngrok.io/messages

You'll need the Twilio CLI installed. You'll need to "upgrade" to paid if you want to remove the Twilio branding from the SMS replies.

Dependencies

Install the dependencies:

npm install

Environment Variables

Copy the .env.example file to .env:

cp .env.example .env

Fill in your TWILIO and OPENAI Keys, and your personal PHONE_NUMBER.

Compile the TypeScript to JavaScript

Compile the project:

npm run build

Note that this runs the TypeScript compiler, tsc, you could also run npx tsc to get the same output.

The TypeScript project will be compiled into the dist directory. You can also continuously compile the project as it changes with:

npm run watch

Run the project

Start the web server with:

npm start

Expose the local server with ngrok

To respond to an incoming webhook you will need a publicly available URL. ngrok is a tool that can tunnel through from a public URL to your machine. Once you've downloaded and installed ngrok you can run it like so:

ngrok http 3000

The ngrok terminal will show you a URL, like https://RANDOM_STRING.ngrok.io.

Connect your phone number to your app

Using the ngrok URL from the last part, you can set up your Twilio phone number with your application. Edit your phone number and in the Messaging section, next to when "A message comes in" enter your ngrok URL with the path /messages.

https://RANDOM_STRING.ngrok.io/messages

Save the phone number and you are ready. Send your number a message and receive a reply. Type "reset" to reset the chat thread history and bdeing again.

GPT3 Example Integration

const { Configuration, OpenAIApi } = require("openai");

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

const response = await openai.createCompletion({
  model: "text-davinci-003",
  prompt: "Please reply to the chat below:\n",
  temperature: 0.7,
  max_tokens: 256,
  top_p: 1,
  frequency_penalty: 0,
  presence_penalty: 0,
});
