A lot has been said about Microsoft Copilot lately, as the company has pushed the artificial intelligence chatbot very hard in recent weeks. Aside from expanding Copilot offerings within Windows 11, Microsoft is also adding a physical Copilot key to its laptops. Whether you love or hate Microsoft’s transition to the ‘Windows as a service’ model, the newly-released Copilot app for iOS and Android is worth a look. This free app offers access to OpenAI’s DALL-E 3 and GPT-4 artificial intelligence models. To get GPT-4 from OpenAI’s ChatGPT app, you’ll need to pay a hefty $20 monthly for the ChatGPT Plus subscription.
