Write cited research reports from DuckDuckGo search results
UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 22 nodes and runs when someone submits an n8n form (“Research a question”). Along the way it connects OpenRouter Chat Model and Duckduckgo Search (community).
How it runs
Trigger: When someone submits an n8n form (“Research a question”).
- Research settings (Code): runs custom JavaScript code
- Plan sub-questions (Basic LLM Chain): sends a prompt to an LLM, with model: OpenRouter model; output parser: Sub-question format
- Cap the sub-questions (Code): runs custom JavaScript code
- Loop over sub-questions (Loop Over Items (Split in Batches)): loops over the items in batches
- Number the sources (Code): runs custom JavaScript code
- Search DuckDuckGo (Duck Duck Go): search
- Enough evidence? (If): checks a condition and branches into true / false
- Grade the evidence (Code): runs custom JavaScript code
- Extract quoted findings (Basic LLM Chain): sends a prompt to an LLM, with model: OpenRouter model; output parser: Finding format
- Explain why there is no report (Code): runs custom JavaScript code
…plus 8 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-duckduckgo-search is verified or supports 3.0 (used in Search DuckDuckGo).

From the author
Quick overview Ask a question in a form; this workflow searches the web with DuckDuckGo and has an OpenRouter model write a report in which every claim cites a page it read, with every quote checked against its source. Self-hosted n8n only. How it works 1.…
