Brain-delta web research compares your existing knowledge context against new web searches to emphasize only what has changed. It reads your supplied brain context and highlights the delta, avoiding the need to re-read and re-summarize previously known information.

Cited web research enforces citation rules where every claim produced from web searches lands with a verifiable source URL. This structured output ensures entity enrichment and current-state checks are backed by traceable references rather than unverified summaries.

Deal or company monitoring can be automated by querying web sources and synthesizing results into a structured research page. This process extracts developments, confirming signals, and contradictions, then writes them into a research file with citations for freshness deltas.

Yes, performing brain-augmented web research requires a Perplexity API or CLI call to search and synthesize sources. The process also needs a provided brain context to compare against, ensuring the results reflect verifiable updates rather than simple URL fetching.

Brain-delta research formats output as a structured markdown page written to a research directory. This page includes an executive summary, developments, confirming signals, contradictions, recommended brain updates, and a citations section for clear knowledge updates.

You should avoid using simple URL fetching for current-state checks when verifiable citations are required. Instead, use a research approach that synthesizes sources and enforces citation rules to ensure claims are backed by verifiable source URLs.
