AI Deep Research Agent: n8n, Apify & OpenAI o3

This n8n workflow creates a self-hosted AI Deep Research Agent, mimicking OpenAI's pro-only DeepResearch feature. Users submit a research query and depth preference via a form, triggering a blank Notion page creation for the final report. The agent then performs recursive web searches and scraping using Apify to gather extensive data, synthesizing partial learnings iteratively.

Once data collection completes, all insights are fed into an OpenAI o3 reasoning model to produce a comprehensive report. The report is automatically written to the Notion page, providing a polished, shareable output. This setup leverages n8n's strengths in automation, web tools, and AI integration for scalable research without subscription limits.

Benefits include massive cost savings over OpenAI Pro, full customizability for business needs, and team-wide access to advanced research capabilities. Use cases span market analysis, competitive intelligence, academic research, content creation, and due diligence—any scenario requiring deep, synthesized web insights. Customize for specific domains by tweaking prompts or adding integrations.
