Perplexity + Claude Gmail Research Brief n8n Workflow

Turn research requests into a cited executive brief—automatically sent by Gmail

This Perplexity + Claude Gmail Research Brief n8n workflow collects a topic from an n8n Form, runs live web research with Perplexity (sonar-pro), synthesizes it with Claude Sonnet (Anthropic), then emails a polished HTML executive brief to the requester and logs everything to an n8n Data Table.

What this workflow does

• Receives a research request via an n8n Form Trigger, capturing the requester’s email, topic, and optional specific questions.
• Normalizes inputs into consistent email/topic/focus values for reliable downstream processing.
• Performs recent web research using Perplexity (sonar-pro), limited to the last month, returning findings plus citation URLs.
• Synthesizes an HTML brief with Claude Sonnet, producing a structured report (summary, key findings, opportunities/risks, and sources).
• Logs the result—topic, questions, the HTML brief, sources, and a timestamp—into an n8n Data Table (default: research_brief_log).
• Sends the brief via Gmail using a configured Gmail OAuth2 connection.

Use cases

• SaaS operators generate weekly research memos for product or market decisions.
• Automation engineers build an inbound “research as a service” flow for internal teams.
• Founders submit a topic and get a cited executive update suitable for sharing with stakeholders.

Technical details

• Nodes / integrations: set, form trigger, Perplexity, Claude (Anthropic), Gmail, data table, sticky note.
