perplexity-research

Web delta research compares your existing brain pages against a fresh Perplexity search to surface only new developments. It passes your prior context into the search prompt to synthesize cited updates focused on the knowledge gap.

Brain-first delta research incorporates existing gbrain pages as context before running a Perplexity web search. It focuses the synthesis strictly on the delta versus your brain knowledge, ensuring you do not re-read already-known facts.

Perplexity research enforces citation coverage in its final output and writes the synthesized findings to a structured research markdown page. This page includes recency tracking and specific update recommendations for your brain.

Yes, delta research applies directly to entity enrichment, current-state checks, deal monitoring, and freshness deltas. It requires passing dense brain context into the Perplexity prompt to identify what changed.

No, this delta research approach requires existing brain coverage to function properly. The core mechanism relies on passing dense brain context into the Perplexity prompt to identify and synthesize the delta versus known facts.

Running a Perplexity web search with your brain context injected is the best way to track freshness deltas. It generates a research page with recency tracking and update recommendations based on the newly surfaced information.
