Workflow name
Build comprehensive literature reviews with GPT-4 and multi-database search

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

Comprehensive Literature Review Automation

Automate your literature review process by searching across multiple academic databases, parsing papers, and organizing findings into a structured review document.

Features:

  • Search multiple academic databases simultaneously (PubMed, ArXiv, Google Scholar, etc.)
  • Parse and analyze top papers automatically
  • Generate citation-ready summaries
  • Export to various formats (Markdown, Word, PDF)

Workflow Steps:

  1. Input: Research topic and parameters
  2. PDF Vector Search: Query multiple academic databases
  3. Filter & Rank: Select top relevant papers
  4. Parse Papers: Extract content from PDFs
  5. Synthesize: Create literature review sections
  6. Export: Generate final document

Use Cases:

  • PhD students conducting systematic reviews
  • Researchers exploring new fields
  • Grant writers needing background sections

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/7354/7354.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
