What this workflow does

This AI workflow has 26 nodes and runs on a schedule (cron 0 0 17 * * *) (plus 2 other triggers). Along the way it connects Reddit and OpenRouter Chat Model. It also calls community.n8n.io over HTTP.

How it runs

Trigger: On a schedule (cron 0 0 17 * * *) (plus 2 other triggers).

1. Get latest 50 reddit posts (Reddit): get many
2. Get Posts sorted by replies (HTTP Request): calls community.n8n.io
3. Select Post Title & Body (Edit Fields (Set)): sets 8 fields: subreddit, title, post…
4. Extract links (HTML): parses or builds HTML
5. Text Classifier: classifies text into categories with AI, with model: OpenRouter Chat Model
6. Process Each Forum Link (Split Out): splits a list into separate items
7. Filter: keeps only the items that match a condition
8. Fetch Individual Forum Posts (HTTP Request): calls an HTTP API
9. Summarize Reddit Questions (Basic LLM Chain): sends a prompt to an LLM, with model: OpenRouter Chat Model; output parser: Format Reddit Summary
10. Combine Reddit Post & Summary (Merge): merges the data from its input branches

…plus 8 more steps. See the full node list below.
