Featured Challenge:
#188 — Voice Chatbot

In this coding challenge, I build a conversational voice chatbot entirely in the browser with p5.js. I combine three pieces: speech-to-text with OpenAI's Whisper model, text-to-speech with Kokoro TTS, and a "brain" for the bot. I also explore the transformers.js pipeline API and the Web Audio API. For the bot's brain, I start with a simple ELIZA-style therapist, then incorporate a RiveScript number-guessing game, and finally a local LLM.

Flappy Bird game

In this challenge, I use my JavaScript neural network library and a genetic algorithm to train an agent to play Flappy Bird.

Sure, flappy bird is fun, but what happens if we take away the button and control the bird with clapping! Yes, it's time for Clappy Bird!

It's time to attempt to build a Flappy Bird clone in JavaScript with the p5.js!
