Slack-OpenAI Assistant for DMs & @Mentions

This workflow creates an AI-powered Slack bot using OpenAI Assistant that responds naturally to direct messages (DMs) and @mentions in channels. It listens for Slack events, filters out bot responses to avoid loops, processes message types, sets a typing indicator for natural flow, generates contextual AI responses with conversation memory (up to 5 recent messages), and replies in threads or DMs accordingly.

Teams benefit from seamless AI assistance within Slack, eliminating the need to copy-paste messages to ChatGPT and preserving discussion context. It saves time for customer support, internal help desks, and collaborative teams by providing quick, knowledgeable responses powered by custom OpenAI instructions and knowledge base.

Ideal for organizations seeking productivity gains through integrated AI. Setup involves Slack app permissions, OpenAI credentials, and customization, taking 20-25 minutes. The workflow ensures intelligent, context-aware interactions that enhance communication efficiency.
