How to Research with ChatGPT
  • ChatGPT

You can't judge a market, a competitor, or an investment without doing the research first. That means hours of open tabs and half-read reports.

ChatGPT's deep research does it for you. It turns a question into a documented, cited report you can verify and act on, whether the next step is a decision or a draft.

By the end of this guide, you'll:

  • Understand when deep research is worth it, and when to skip it.
  • Use research prompts from a library, or build your own, to produce documented reports.
  • Feed that research into your work, so your next decision or draft starts from real material.

Note: Deep research is one way to practice context engineering: the more relevant context you give AI, the better its output. You won't always need it. When you already have the research, feed that in instead. It pairs with your AI writing system, which gives AI your audience, message, and voice.

What is deep research?

Deep research is ChatGPT's tool for in-depth questions. Instead of answering from memory, it reasons, searches the web and your uploaded files, and synthesizes what it finds. The result is a structured report with citations you can verify.

It's different from a normal chat or a quick web search. A quick search returns a short summary with links. Deep research reads and analyzes many sources, then produces a detailed, documented report. Reach for it when a question is multi-step and needs synthesis across sources, like a market analysis or a competitor breakdown. Skip it for a quick fact.

Before you start: deep research usage depends on your plan, so a Plus subscription or higher is recommended. It isn't working in the desktop app right now, so run it on the web (chatgpt.com). Deep research runs on the latest model automatically.
