In a rapid move to expand its AI chatbot’s reach, Microsoft released standalone Android and iOS apps for Microsoft Copilot. The AI assistant, powered by OpenAI’s GPT-4, offers quick responses to user queries in text format, and the iOS version includes a feature to convert speech into images using OpenAI’s DALL-E 3 technology. This mobile rollout follows the rebranding of Bing Chat to Copilot and its integration with Windows 10 and 11, further extending the potential user base to around a billion devices.
