FAQ
Common questions
Short answers to the questions people usually have before choosing a tool or service.
What is the best AI tool for beginners?
A general assistant such as ChatGPT, Gemini, Claude or Copilot is usually the easiest starting point. The best choice depends on whether you need writing, research, coding, search or integration with tools you already use.
Can I use useful AI tools for free?
Yes. Many services have free plans, but limits may apply to messages, advanced models, files, image credits or peak-time access.
Should I use one AI tool for everything?
Usually not. Start with one general assistant and add a specialist only when it produces a clearly better result for a repeated task.
