AI
Models that learn from data. Here are all 25 working models in this field — each with a full build and working principle.
Hand-Drawn Digit Classifier
Train a tiny neural network in the browser to recognise digits you draw with a mouse.
Rock-Paper-Scissors Vision
Use a webcam and a no-code model to recognise your hand and play rock-paper-scissors.
Spam Email Classifier
Train a model on example messages so it can flag new ones as spam or not.
Sentiment Analyzer
Feed in movie reviews and the model tells you whether each one is positive or negative.
Cats vs Dogs Classifier
Train an image model to tell cats from dogs and test it on your own photos.
Beginner Chatbot
Build a chatbot that answers questions, starting with rules and growing toward learning.
House Price Predictor
Fit a model to housing data so it estimates a price from size, rooms and location.
Letter Recognizer
Extend digit recognition to handwritten letters and read words you write.
Face Detection Counter
Use a ready model to detect faces in a webcam feed and count how many it sees.
Voice Command Recognizer
Train a model to tell a few spoken words apart and trigger actions from your voice.
Movie Recommender
Suggest films a user might like based on what similar users enjoyed.
Plant Disease Detector
Train an image model to spot diseased leaves from healthy ones in photos.
Pose-Detection Game
Use body-pose tracking so your movements control an on-screen game.
Webcam Object Detector
Run a pre-trained model that names and boxes objects in your camera view live.
Music Genre Classifier
Train a model to guess a song's genre from short audio clips.
Weather Predictor
Use past weather data to predict tomorrow's temperature with a simple model.
Tic-Tac-Toe AI
Program an unbeatable opponent that plans ahead using the minimax algorithm.
Self-Playing Snake
Give the snake game a simple AI that chases food and avoids walls on its own.
Colour Detector
Train a tiny model (or rules) to name colours from camera input and sort them.
Mini Translator
Build an app that translates typed text using a translation API.
Fake News Detector
Train a model to flag likely-misleading headlines from real ones.
Emotion Detector
Use a model to guess facial expressions like happy, sad or surprised from a webcam.
Hand Gesture Recognizer
Recognise hand signs from a webcam and map them to letters or commands.
Smart Traffic Light
Simulate an intersection where an AI adjusts light timing to ease traffic.
Iris Flower Classifier
Train the classic beginner model to identify iris species from four flower measurements.
