What this workflow does

This AI workflow has 19 nodes and runs when someone submits an n8n form (“Upload 3 Images for Analysis ”). Along the way it connects Google Drive, OpenAI, OpenAI Chat Model and Google Sheets. It also calls tmpfiles.org and api.atlascloud.ai over HTTP.

How it runs

Trigger: When someone submits an n8n form (“Upload 3 Images for Analysis ”).

1. If: checks a condition and branches into true / false
2. Normalize binary names (Edit Fields (Set)): sets 3 fields: image0, image1, image2
3. Error Response - Missing Files (Edit Fields (Set)): sets 1 field: error
4. Split images (Code): runs custom JavaScript code
5. Upload file (Google Drive): uses Google Drive
6. Analyze image (OpenAI): analyze (image)
7. Build Public Image URL (HTTP Request): calls tmpfiles.org (POST)
8. Merge: merges the data from its input branches
9. Aggregate descriptions (Code): runs custom JavaScript code
10. Generate Image Prompt (AI Agent): runs an AI agent, with model: OpenAI Chat Model; output parser: Structured Output Parser

…plus 6 more steps. See the full node list below.
