Demo NextJS app featuring the ChatGPT and Whisper APIs

ChatGPT + Whisper API NextJS Demo

This project was created to play around with the Whisper and ChatGPT APIs from OpenAI.

Here's what it does:

  • Uses the microphone on your web device to interact with ChatGPT similar to Siri.
  • Sets a default context for ChatGPT where you can configure its role, personality, and brevity of its responses.
  • Just like ChatGPT, it remembers your conversation
  • Button to reset the conversation.

What's so cool about this?

  • Talking is easier than typing and the Whisper API does a great job at translating speech to text.
  • Refining the context of ChatGPT allows its responses to be extremely relevant to you.
  • With the context pre-defined, you can save a lot of time interacting with ChatGPT.

Configuring ChatGPT Context

Open up pages/index.tsx and note the following areas that can be configured:

// roles
const botRolePairProgrammer =
  'You are an expert pair programmer helping build an AI bot application with the OpenAI ChatGPT and Whisper APIs. The software is a web application built with NextJS with serverless functions, React functional components using TypeScript.';
const nocontext = '';

// personalities
const quirky =
  'You are quirky with a sense of humor. You crack jokes frequently in your responses.';
const drugDealer =
  'You are a snarky black market drug dealer from the streets of Los Angeles. Sometimes you are rude and disrespectful. You often curse in your responses.';
const straightLaced =
  'You are a straight laced corporate executive and only provide concise and accurate information.';

// brevities
const briefBrevity = 'Your responses are always 1 to 2 sentences.';
const longBrevity = 'Your responses are always 3 to 4 sentences.';
const whimsicalBrevity = 'Your responses are always 5 to 6 sentences.';

// dials
const role = botRolePairProgrammer;
const personality = quirky;
const brevity = briefBrevity;

// FULL BOT CONTEXT
const botContext = `${brevity}`;

Add your own roles to cater it to your needs.

ENV setup

To use the OpenAI API you must generate an OpenAI API key, create a file called .env.local at the root level of this project, and set the following environment variable: OPENAI_API_KEY={your OpenAI API key}

Deploying on Vercel

This project is setup to deploy on the free version of vercel, just clone and add it to your project and deploy it to production.

Special note: In order for this to deploy and work properly on Vercel, you must use Node 16.x for your serverless functions.

Boilerplate stuff:

This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying pages/index.tsx. The page auto-updates as you edit the file.

API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.ts.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.
