What this workflow does

This AI workflow has 22 nodes and runs on Gmail events. Along the way it connects Gmail, Discord and OpenAI Chat Model.

How it runs

Trigger: On Gmail events.

1. Loop Over Items (Loop Over Items (Split in Batches)): loops over the items in batches
2. Get many labels (Gmail): work with label
3. Merge: merges the data from its input branches
4. Filter: keeps only the items that match a condition
5. Merge: merges the data from its input branches
6. Basic LLM Chain: sends a prompt to an LLM, with model: OpenAI Chat; output parser: Structured Output Parser
7. Aggregate: combines items into one
8. Code: runs custom JavaScript code
9. Add old_labels [] (Edit Fields (Set)): sets 3 fields: output, output.old_labels, output.added_label_names
10. Split Out: splits a list into separate items

…plus 9 more steps. See the full node list below.
