Frequently Asked Questions

Can AI write research papers?

AI can help draft sections and organize arguments, but should not generate entire papers. Most journals require AI disclosure.

Which AI has the largest context window?

Gemini Pro at 1M tokens (~750K words), then Claude at 200K tokens (~150K words).

Is AI reliable for literature reviews?

Helpful for identifying themes, but can hallucinate paper titles/authors. Always verify citations independently.
