Choosing ai research & search
Are AI search citations always reliable?+
No. A citation can exist yet fail to support the exact claim. Open purchase-critical and high-stakes sources, check the publication date, and distinguish primary evidence from summaries.

AI search is designed around retrieval and source-backed synthesis. A general chatbot may also search, but often prioritizes broader creation, analysis, and conversation workflows.
