Humane Inc., the startup founded by former Apple Inc. design and engineering team Imran Chaudhri and Bethany Bongiorno, has officially launched its long-awaited Ai Pin — making a splashy foray into the nascent field of artificial intelligence hardware.

The device can magnetically clip onto clothing and will cost $699 with a $24-a-month subscription — which will come with unlimited data and phone calls. The company also said it would partner with T-Mobile for phone service and Microsoft Corp. and OpenAI for AI technology. The device will be available to order starting Nov. 16.
