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.
