How to research with AI without losing the sources
A fluent answer is not evidence. AI can accelerate discovery and synthesis, but sound research preserves the path from every important claim to an original, dated and relevant source.

The short answer
Use AI to frame questions, expand vocabulary and find leads. Then open the sources and identify author, date, scope and method. Draft only after building a claim-to-source table, and mark what remains uncertain.
- AI discovers; sources demonstrate
- Date every changing claim
- Read every citation in context
From a topic to a verifiable synthesis
1. Turn the topic into questions
Break the need into definition, current state, causes, effects, objections and required data. Fix geography, time period and audience to prevent an uncheckable generic answer.
2. Diversify queries
Ask for synonyms, technical terms, competent bodies and likely document types. Search official reports, research papers, primary documentation and credible dissent separately.
3. Reach the original
A page citing a study is not the study. Open the primary document and record title, author, date, sample and limits. If it is unavailable, label the claim as secondary sourcing.
4. Check time
For prices, laws, features, office-holders or statistics, record both event date and publication date. A new page may repeat old data; an old page may remain the primary source for a historical fact.
5. Re-read citations
Confirm that each source supports the exact sentence, not merely the broad topic. Inspect context, footnotes and studied population. Remove invented, vague or irretrievable references.
6. Separate fact and analysis
Distinguish established data, source interpretation and your own inference. Calibrated language is more useful than artificial certainty.
Evaluate a source with four questions
Who publishes?
Identify the author, institution, expertise and possible interests.
When?
Check publication date, measured period and updates.
How?
Look for method, sample, definitions and limitations.
What does it prove?
Connect the source to one precise claim and preserve context.

Frequently asked questions
Can an AI answer be cited directly?
For factual information, cite the original source you actually consulted. Disclose AI use whenever academic, editorial or professional rules require it.
How can I spot a fabricated reference?
Search the exact title, author, journal or institution and open the identifier or URL. Remove the reference when no coherent document can be found.
How many sources are enough?
It depends on the claims. One strong primary source may support a narrow fact; a disputed topic needs independent sources and opposing evidence.
