Tips & Tricks to Get the Most Out of Perplexity AI
Whether you're a casual user or a power researcher, these tips will help you get smarter, faster, and more relevant results with Perplexity AI.
1. How to Ask Effective Questions
Perplexity responds best to clear, specific, and natural language queries.
Instead of vague prompts like: “Climate change”
Ask:“What are the top 3 causes of climate change in 2024?”
Why it works:
It gives the AI context, direction, and expected structure, leading to more focused, usable answers.
Pro Tip: Add question words like how, why, what, compare, summarize, list, explain to guide the AI.

Tailor your answers by selecting a specific source type:
- Web: For general knowledge or news.
- Academic: Ideal for research papers or factual depth.

- Finance: Best for stock data, earnings reports, or market news.
Use case:
Set the source to Academic and ask, “Explain the Hawthorne effect with recent studies.”

You don’t need to start over with every question. Use follow-ups to go deeper.
- Initial Query: “Explain generative AI in simple terms.”

Why it works:
Perplexity keeps context across the thread, giving more coherent, progressive answers.
