General assistants for questions, writing, planning, analysis and learning.

How to choose

Start with the assistant that fits the apps you already use: Gemini for Google users, Copilot for Windows, Meta AI inside WhatsApp. For long documents and careful writing, Claude is a strong choice; for math and logic, try DeepSeek's reasoning mode. All of them can be wrong, so double-check facts, numbers and quotes before you rely on them.
