FAQ

What is ChatGPT-in-Slack?

A Slack app that lets workspace members chat with OpenAI's ChatGPT and DALL-E models in channel threads, DMs, and the Home tab. ChatGPT in Slack is a Python app that brings ChatGPT into Slack so users can prompt the bot without leaving their workspace. It can be used by mentioning the bot in a channel thread, sending messages in a 1:1 DM, or using dialogs on the Home tab for proofreading, free-form prompts, and image generation with DALL-E 3. Within a thread or DM, the bot keeps the conversation context so follow-up questions build on earlier replies.
