How to Use AI for Research (Without Hallucinated Citations)

The non-negotiable rule: only use AI search engines for finding sources. Never ask ChatGPT, Claude or Gemini to "find papers about X" — they'll happily make some up.

Perplexity on AskAI.free actually browses the web in real time and returns answers with clickable inline citations. The answer might still be wrong, but the citations are real and verifiable.

Even Perplexity's citations need verification. The link works ≠ the source actually says what the AI claims. Click every citation, find the relevant passage, and confirm.

Common failure: AI cites a real paper for a claim the paper doesn't actually make, or cites a paper out of context.

Once you have verified sources, paste them into Claude Sonnet 4 for analysis. Claude's 200K context handles 5-10 papers at once.

"I've pasted 5 papers below. Compare and contrast their findings on X. Where do they disagree? What's the most-cited counter-argument?"

Now you're using AI for what it's actually good at: synthesising information you've already vetted.

Add this to every research prompt:

"For every factual claim you make, indicate your confidence (high/medium/low) and which source supports it. If you're not sure, say so explicitly."

The AI is way more likely to admit uncertainty when prompted. Use the low-confidence claims as a checklist of things to manually verify.

Before citing anything in a paper, find it on Google Scholar yourself. This catches:

• Hallucinated DOIs / titles.
• Authors who exist but didn't write that paper.
• Misattributed quotes (real paper, wrong claim).
• Retracted papers (still in AI training data, no longer valid).

For a literature review, use this flow:

1. Perplexity finds the major papers (5-15) with citations.
2. You read the abstracts to confirm relevance.
3. Claude synthesises the verified set into a structured review.
4. You write the actual review prose, citing the verified sources.

Claude does the heavy lifting on synthesis; you do the verification and writing. Result: real lit review, no hallucinations.
