Web Research Agent (n8n Workflow) — Setup & Run Guide

Chat with an AI agent that scrapes any website and gives you a summarized report, saved automatically to Notion.

Ask it things like:

• "What do people on Reddit think about Arc browser?"
• "Find pricing for Linear vs Jira vs Asana"
• "What are the top complaints about Notion on Reddit?"

The agent decides where to look, scrapes the page with TinyFish, analyzes the results, and saves a clean report to your Notion workspace.

How it works

You (chat message)
  |
  v
Web Agent (LangChain AI Agent)
  |-- uses OpenRouter (Claude Haiku 4.5) for reasoning
  |-- uses TinyFish Web Agent tool for live web scraping
  |
  v
Create Notion Report (saves output as a new Notion page)

1. You ask a question in the n8n chat UI
2. The AI agent decides the best URL and extraction goal based on your question
   • For Reddit questions, it searches old.reddit.com
   • For anything else, it constructs the right URL (pricing pages, review sites, docs, etc.)
3. TinyFish scrapes the page in stealth mode and returns the raw content
4. The agent analyzes the scraped data and produces a concise summary
5. A Notion page is created with the full report, titled with your query and the date

Prerequisites

Accounts / API keys you need

Software

• n8n (Desktop, Docker, or Cloud) — see n8n docs if you need help installing
• n8n-nodes-tinyfish community node (installed inside n8n)

1) Install & open n8n

Option A — n8n Desktop (easiest)

1. Download and install n8n Desktop
2. Open it — n8n runs at http://localhost:5678

Option B — Docker

docker run -it --rm \
  -p 5678:5678 \
  -v ~/.n8n:/home/node/.n8n \
  n8nio/n8n

Then open http://localhost:5678.

2) Install the TinyFish community node

1. In n8n, go to Settings > Community Nodes
2. Click Install
3. Enter: n8n-nodes-tinyfish
4. Install and restart n8n if prompted

3) Import the workflow

1. In n8n, click Workflows > Import from file
2. Select Web Research Agent via Tinyfish.json
3. Click Save

You should see 4 nodes on the canvas:

• When chat message received (trigger)
• Web Agent (LangChain AI agent)
• OpenRouter Chat Model + TinyFish Web Agent (connected as sub-nodes)
• Create Notion Report (output)

4) Set up credentials

4.1 TinyFish

1. Go to Credentials > New
2. Search for TinyFish Web Agent
3. Paste your TinyFish API key
4. Save
5. Open the workflow and assign this credential to the TinyFish Web Agent node

4.2 OpenRouter

1. Credentials > New
2. Search for OpenRouter
3. Paste your OpenRouter API key
4. Save
5. Assign to the OpenRouter Chat Model node

The workflow defaults to anthropic/claude-haiku-4.5. You can change the model in the node settings — OpenRouter supports hundreds of models.

4.3 Notion

1. Go to notion.so/my-integrations
2. Click New integration
3. Give it a name (e.g., "n8n Web Research")
4. Copy the Internal Integration Secret
5. In Notion, open the parent page where you want reports saved
6. Click ... > Connections > add your integration
7. In n8n: Credentials > New > Notion API
8. Paste the integration secret
9. Save and assign to the Create Notion Report node
10. Update the Page ID in the node to point to your own Notion page

5) Running the workflow

1. Open the workflow in n8n
2. Click Execute workflow (or toggle Active to keep it running)
3. The n8n chat panel opens — type your question:

What do people on Reddit think about Cursor IDE?

1. The agent will:

   • Decide to search Reddit for "Cursor IDE"
   • Call TinyFish to scrape the search results
   • Summarize the findings
   • Save a report to Notion

2. You'll see the response in the chat and a new page in your Notion workspace

Example queries

Customization ideas

• Change the LLM: Swap anthropic/claude-haiku-4.5 for any model on OpenRouter (GPT-4o, Llama, Mistral, etc.)
• Change the output: Replace the Notion node with Slack, Google Sheets, email, or any other n8n node
• Add memory: Attach an n8n memory node to the agent for multi-turn conversations
• Adjust the system prompt: Edit the Web Agent's system message to change behavior, output format, or target sites

Troubleshooting

"TinyFish returned no data"

• The site may be blocking scraping — try a different URL or query
• Check your TinyFish API key is valid and has remaining credits

Notion page not created

• Make sure your integration is connected to the parent page in Notion
• Verify the Page ID in the Create Notion Report node matches your workspace

OpenRouter errors

• Check your API key and account balance at openrouter.ai
• Some models may have rate limits — try a different model if one fails

Quick checklist before first run

• Workflow imported
• TinyFish credential added and assigned
• OpenRouter credential added and assigned
• Notion integration created and connected to parent page
• Notion Page ID updated in the Create Notion Report node
• Test with a simple query like "What is TinyFish?"
