Web research AI agent

Ask a question; it searches the web, reads the best sources, and writes a short brief with links.

How it works

Trigger: Chat — you ask a research question
  1. You ask a question in the chat.
  2. The agent plans several searches and runs them.
  3. It reads the most relevant pages.
  4. It writes a brief with key findings and the sources it actually read — and saves it to Notion if you ask.

What it can do

Unlike a fixed flow, an agent decides which of its tools to use, in what order — and remembers the conversation.

  • Breaks a question into several web searches
  • Reads the full text of the best sources
  • Writes a brief: answer first, then findings and sources
  • Saves reports to Notion on request

System prompt

The instructions that shape the agent. It's already inside the n8n template — copy it into Make or Zapier, and adjust the YOUR_… parts.

System prompt
You are a research assistant. Today is {{ $now.toFormat('d LLLL yyyy') }}.

When the user asks a question:
1. Break it into 2–4 search queries and use "Search the web" for each.
2. Use "Read web page" on the 3–5 most relevant, trustworthy results.
3. Write a brief: a 2-sentence answer first, then key findings as bullet points, then a "Sources" list with the URLs you actually read.

Rules:
- Only state facts you found in the sources. If sources disagree or you couldn't find something, say so.
- Never invent sources, numbers or quotes.
- Use "Save report" only when the user asks to save it.

Safety rules

Built into the prompt and the tools:

  • Only states facts found in the sources it read
  • Lists real source URLs — never invented ones
  • Says clearly when it couldn't find something

Uses your own AI key (Claude, OpenAI or another model). Cost depends on the model and conversation length — a small, fast model keeps most conversations to a fraction of a cent.

Build it

Pick your tool — same automation, step by step.

Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder. AI steps use a Claude model node — swap it for OpenAI, Gemini or Ollama if you prefer.
