Sources and citations

Sources and citations

Grep includes sources and citations so you can see where an answer came from and verify important claims before using the result.

What sources are

Sources are the pages, documents, or references Grep used while researching your task. Depending on the task, sources may include company websites, public filings, articles, reports, help docs, or other web pages.

The sources panel helps you understand:

  • Which materials Grep reviewed.
  • Which sources support the final answer.
  • Whether a claim needs additional verification.
  • Where to go if you want to read the original material.

What citations are

Citations connect specific claims in the answer to supporting sources. When you see a citation marker, open it to inspect the source behind that claim.

Citations are especially useful for:

  • Numbers and statistics.
  • Pricing claims.
  • Company descriptions.
  • Regulatory or policy statements.
  • Quotes or paraphrased claims from source material.

How to review an answer

Before you share or act on a Grep result, review the answer in three passes:

  1. Read the summary to confirm the answer addresses your question.
  2. Open the sources to check the quality and relevance of the materials.
  3. Verify key citations for claims that matter to your decision.

For high-stakes work, always verify the most important claims directly in the original sources.

What to do if a source looks weak

If a source seems outdated, irrelevant, or low-quality, ask a follow-up question that narrows the source requirements.

Examples:

  • “Use only sources from the last 12 months.”
  • “Prioritize company websites, SEC filings, and official announcements.”
  • “Exclude blog posts and forum discussions.”
  • “Find stronger evidence for the market size estimate.”

Why citations may not cover every sentence

Some parts of an answer are synthesis: Grep combines evidence across sources to produce a summary, recommendation, or comparison. Citations are most important for factual claims, not every transition or conclusion.

If you need tighter support, ask Grep to “add citations for every factual claim” or “separate sourced facts from analysis.”

Best practices

  • Treat Grep as a research assistant, not a final authority.
  • Verify critical facts before external use.
  • Ask follow-ups when sources are missing or too broad.
  • Prefer official, primary, and recent sources for important decisions.
  • Export the result with citations when sharing with a team.
