SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you research what is new on a topic by combining your existing brain knowledge with fresh web search, so you don’t waste time re-reading already-known facts.

Core Features & Use Cases

Brain-first delta research: sends brain context into a Perplexity prompt so results focus on what changed versus what the brain already knows.
Cited, verifiable output: produces a structured research page where claims are supported by web citations.
Brain update guidance: recommends specific page updates that incorporate the new findings.

Quick Start

Ask the agent: perform perplexity-research on Brex and surface NEW developments.

FAQPage Schema

How do I find new web developments on a topic I already have notes on?▼

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.

What is brain-first delta research for monitoring current-state changes?▼

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.

How do I get cited, verifiable web research results written to my knowledge base?▼

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.

Can I use existing brain context for entity enrichment and deal monitoring?▼

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.

Does web research with Perplexity work without prior brain coverage on a topic?▼

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.

What's the best way to track freshness deltas versus existing knowledge pages?▼

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.
