Frequently Asked Questions

Is Comet/Perplexity better than ChatGPT for students?

Not necessarily "better" - just different. Perplexity excels at research and provides citations, while ChatGPT is better for explanations and problem-solving. Most students in our community use both for different purposes.

Can I use browser AI tools for assignments?

These tools are fine for research and understanding concepts, but check your school's AI policy. Never submit AI-generated content as your own work. Use these tools to learn, not to bypass learning.

Are browser extensions safe?

Official extensions from reputable companies (OpenAI, Perplexity, Microsoft, Google) are generally safe. Always download from official browser stores. Be cautious with third-party AI extensions.

Do I need the paid version?

Most students report the free tiers are sufficient. Only upgrade if you're consistently hitting limits and the tool genuinely saves you significant time. Don't pay for something you use occasionally.
