n8n Slack & Knowledge Management Workflow - project visual

The Problem

Teams need a single interface to schedule meetings, query data, handle email, and search across documents without switching tools.

Approach

Built an n8n workflow with a central AI agent triggered by Slack.

Dedicated sub-agents handle Google Calendar (create/update/delete events, get events), Gmail (send messages), and Postgres (chat memory, SQL).

Google Drive file triggers ingest PDF, Excel, CSV, and TXT into Supabase vector store with OpenAI embeddings and text chunking for semantic search.

Results

Scalable system for team collaboration: smart scheduling, contextual Slack memory, automated email, and AI-assisted document search over Drive files, with database setup and document metadata tables.

Key result: Unified Slack, Calendar, Gmail, and document search in one AI-driven system
