Get a research report with real sources
“I need to understand a topic well and want every claim backed up.”
Deep-research tools read dozens of sources and write a cited report. Ask them to separate strong evidence from weak, and check a few key sources yourself.
Fix it yourself in 3 steps
- Write your question and what you'll use the answer for.
- Ask for a report with citations for every claim and a 'how sure' note for each section.
- Open the 3 most important sources yourself before relying on them.
Copy this prompt
Research: [question]. I'll use this to [purpose]. Write a report with a 5-line summary, then sections with a citation link for every claim. Rate each section's evidence strong/mixed/weak and list what's still unknown. Prefer primary sources. Don't make claims you can't cite. Stop after the report.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
