The Only Assistant You’ll Ever Need
Forget about Alexa – Spencer is the real deal (and a lot cooler, if you ask us).
Build & code your AI assistant from scratch and get a quirky assistant with a corny sense of humor.
It will read your news, set your alarms, remind you about calendar meetings, read the weather forecast, and much more. The experience of Spencer “coming to life” is unbeatable.
Bring Your Digital Pet To Life
Unlike other pets, you can take a break from CircuitPet.

Even better, you can code your custom games to have fun with your virtual pet!
Tons Of Fun

Need help with building or coding?
Our amazing customer success manager Monika will point you in the right direction for hassle–free assembly & coding experience
I purchased a Nibble for my son who damaged the board when soldering. I contacted Monika at customer service and she sorted our problem with ease and only charged for the damaged board which was sent quickly and resulted in a happy young man.
Highly recommended.
