If you’ve ever tried using Perplexity’s Deep Research or OpenAI’s Deep Research, you know how powerful these tools can be for tackling complex questions, compiling reports, or gathering insights from across the web. But with free tiers offering only a handful of premium queries each month, every Deep Research credit is precious. So, how do you make sure you get the absolute best results from each use?
Here’s a simple, actionable strategy: before using your limited Deep Research credits, ask your favorite LLM (like ChatGPT, Gemini, or Perplexity) to help you craft the perfect prompt. This extra step can dramatically improve the quality of the final research, ensuring you get maximum value from every query.
Let’s break down this process, step by step.
Why Optimizing Your Prompt Matters
Deep Research tools are only as good as the instructions you give them. A vague or unfocused prompt can lead to generic, shallow, or even irrelevant results. On the other hand, a well-crafted prompt guides the AI to dig deeper, cover all your angles, and produce a report that truly meets your needs.
Step-by-Step: Get the Most Out of Your Free Deep Research Credits
Step 1: Define Your Research Goal
Start by clearly stating what you want to achieve. Is it a market analysis, a technical comparison, a policy overview, or something else? The more specific you are, the better.
Example:
“I want a detailed comparison of electric vehicles released in 2024, focusing on range, price, and safety features.”
Step 2: Ask the LLM to Optimize Your Prompt
Before using your Deep Research credit, open your favorite LLM chat (like ChatGPT or Perplexity) and ask:
“You are a prompt engineer. Help me optimize this prompt for Deep Research: [insert your research goal].”
The LLM will often ask clarifying questions or suggest ways to make your prompt clearer and more targeted. This back-and-forth helps refine your request so that the Deep Research tool knows exactly what you need.
Step 3: Use the Optimized Prompt in Deep Research
Once you have your improved prompt, copy it into your Deep Research tool of choice. This step ensures that your limited query is used to its fullest, delivering a comprehensive and relevant report.
Step 4: Review and Follow Up
After Deep Research delivers its results, review the output carefully. If you need more detail or a different angle, you can repeat the process (if you have credits left) or use the LLM in standard mode to dig deeper into specific points.
Example Workflow
- Initial Idea: “I want to know the pros and cons of buying a new vs. used car in 2025.”
- Prompt Optimization: Ask the LLM: “You are a prompt engineer. Help me optimize this prompt for Deep Research: I want to know the pros and cons of buying a new vs. used car in 2025.”
- LLM Suggests: “Please clarify: Are you interested in specific car types? What’s your budget? Do you want data on depreciation, insurance, maintenance, or resale value?”
- Refined Prompt: “Provide a comprehensive analysis of the advantages and disadvantages of buying a new versus used car in 2025, focusing on total cost of ownership, depreciation, insurance, maintenance, and resale value. Include recent data and expert opinions.”
- Paste into Deep Research: Use this refined prompt to get a thorough, well-structured report.
Tips for Getting the Best Results
- Be Specific: The more details you provide, the better the research.
- Use Follow-Up Questions: If Deep Research asks for clarification, respond thoughtfully.
- Iterate: Don’t hesitate to tweak your prompt and try again if you’re not satisfied.
- Fact-Check: Always review the sources and double-check any critical facts, especially for important decisions.
Final Thoughts
By investing a few extra minutes to optimize your prompt, you can unlock the full potential of Deep Research-even on a limited free plan. This simple workflow ensures that every query counts, saving you time and delivering richer, more actionable insights.
