What this workflow does
This AI workflow has 25 nodes and runs on a schedule (every day at 02:00) (plus 2 other triggers). Along the way it connects Notion, Google Drive, Pinecone Vector Store and Embeddings OpenAI and 2 more.
How it runs
Trigger: On a schedule (every day at 02:00) (plus 2 other triggers).
- Search Notion Pages (Notion): search
- Search Drive Files (Google Drive): work with file folder
- Strip Mention (Code): runs custom JavaScript code
- Notify Ops (Slack): uses Slack
- Combine Doc Sources (Merge): merges the data from its input branches
- Answer Question (AI Agent) (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 1 tool (Knowledge Base (RAG Tool))
- Normalize Doc List (Code): runs custom JavaScript code
- Reply in Thread (Slack): uses Slack
- Process Each Doc (Loop Over Items (Split in Batches)): loops over the items in batches
- Is Notion Doc? (If): checks a condition and branches into true / false
…plus 6 more steps. See the full node list below.

Quick overview This workflow syncs Notion pages and Google Drive files into a Pinecone vector index nightly, then answers Slack @mentions using an OpenAI chat model with retrieval from that Pinecone knowledge base and replies with a source URL. How it works…
