In the realm of contemporary tech products, AI hardware has emerged as a focal point, attracting considerable attention but also sparking numerous inquiries. Ranging from the $699 Humane Ai Pin to the $200 Rabbit R1, these AI startups all assert that specialized hardware is essential for experiencing genuine AI capabilities. Now, AI Key has entered the competition. AI Key is an external hardware gadget marketed as an 'AI assistant.' It's a plug-and-play device that connects to an iPhone via its USB port, enabling users to control mobile apps and functions through voice commands for a wide array of common tasks. Featuring a compact design and available in three colors, it's priced at $89. The manufacturer has pledged to commence global shipping before Christmas, and the initial batch nearly sold out within a mere seven hours. Nevertheless, the lingering question is whether an extra peripheral device is genuinely necessary to transform a phone into an 'AI phone.'
