Teachable Machine is Google's free browser tool for training real machine learning models without writing code: show it examples of images, sounds, or poses, and it trains a working classifier you can test and export in minutes.

Choose a project type, image, audio, or pose classification, upload or capture examples for each class using your webcam or microphone, and Teachable Machine trains a small neural network live in the browser using TensorFlow.js. Test it immediately with new input, then export as a TensorFlow.js, TensorFlow, or TensorFlow Lite model for use in real projects, websites, apps, or Arduino-class hardware. Everything runs client-side, so no data leaves your browser, which made it a staple for privacy-conscious classroom demonstrations of how ML actually works.

Who is it for?

Students and teachers demonstrating machine learning concepts hands-on, makers prototyping gesture or sound-triggered projects, and anyone who wants to understand training data and classification without a math prerequisite.

How much does Teachable Machine cost?

Completely free, with no account, no tier, and no usage limits, a Google Creative Lab experiment maintained as a public educational resource.

Our verdict

Teachable Machine remains one of the best "aha" tools for demystifying machine learning: watching your own webcam gestures become a trained classifier in real time teaches more than a lecture could. For education and quick prototyping, it is simply excellent and free.
