1.1 Workflow description

Title

Workflow name
Analyze tradingview.com charts with Chrome extension, n8n and OpenAI

This flow is supported by a Chrome plugin created with Cursor AI.

The idea was to create a Chrome plugin and a backend service in N8N to do chart analytics with OpenAI. It's a good sample on how to submit a screenshot from the browser to N8N.

Who is it for? N8N developers who want to learn about using a Chrome plugin, an N8N webhook and OpenAI.

What opportunity does it present? This sample opens up a whole range of N8N connected Chrome extensions that can analyze screenshots by using OpenAI.

What this workflow does? The workflow contains:

  • a webhook trigger
  • an OpenAI node with GPT-4O-MINI and Analyze Image selected
  • a response node to send back the Text that was created after analysing the screenshot.

All this is needed to talk to the Chrome extension which is created with Cursor AI.

The idea is to visit the tradingview.com crypto charts, click the Chrome plugin and get back analytics about the shown chart in understandable language. This is driven by the N8N flow.

With the new image analytics capabilities of OpenAI this opens up a world of opportunities.

Requirements/setup

  • OpenAI API key
  • Cursor AI installed
  • The Chrome extension. Download
  • The N8N JSON code. Download

How to customize it to your needs? Both the Chrome extension and N8N flow can be adapted to use on other websites. You can consider:

  • analyzing a financial screen and ask questions about the data shown
  • analyzing other charts
  • extending the N8N workflow with other AI nodes

With AI and image analytics the sky is the limit and in some cases it saves you from creating complex API integrations.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/2642/2642.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.
