 Artificial intelligence (AI) AI, or artificial intelligence, is like giving a machine a “thinking cap.” It’s the technology that allows machines to mimic human intelligence and perform tasks such as learning, reasoning, problem-solving, and even creativity. It powers everything from voice assistants like Siri, to self-driving cars, to personalized recommendations on streaming platforms. AI works through algorithms and models that process vast amounts of data and make decisions or predictions based on it. Gemini and Copilot are both AI-powered tools, but they serve slightly different purposes: Gemini : Developed by Google, Gemini is a multimodal AI that integrates deeply with Google Workspace tools like Docs, Sheets, and Gmail. It's great for creative tasks, multimedia capabilities, and general consumer applications. Copilot : Created by Microsoft, Copilot is optimized for productivity within the Microsoft ecosystem, including Word, Excel, Teams, and Outlook. It excels at workplace...
