Draw a number in the left-hand box

---

The interface above lets you draw a number in the left-hand box and send it to a neural network to be recognized. The result will appear in the right-hand box.

Not working?

Please note: the app is running over at Heroku, which is a free service that unloads the app from memory if it's not used for 30 minutes. If the interface above doesn't seem to be working, give it a few seconds to boot up, or try the interface hosted on Heroku. (Similarly, that page may take a little while to load if the app is not running.)

The back-end of this app is a Python Flask application, using keras to load up a pregenerated neural network trained on the MNIST dataset. For more information, see the app's GitHub repository.
