How is an AI assistant different from choosing a model?
An assistant sets the role, character and working style, while the model provides the intelligence. You can switch assistants independently from ChatGPT, Claude, Gemini or another connected model.
Can I use an assistant for study or work?
Yes. The roles include a tutor, editor, marketer and other helpers with starter prompts for specific tasks.
Does an assistant replace a professional?
No. An assistant is AI, not a person: it helps with a task but does not replace a doctor, therapist or lawyer, so verify important decisions and facts.
