ChatGPT Slack Bot

This Slack Bot is implemented in Node.js, under the hood it depends on transitive-bullshit/chatgpt-api, which is a package to help integrating with ChatGPT API.

This service is docker containerized , and has incorporates queue mechanism with redis, so that it is more flexible to handle request spikes, make sure the requests are sent one by one and in order to protect from being rate limited by ChatGPT API.

(Since it is a queue-worker mechanism, you may deploy more workers (under different OpenAI accounts) to listen to a same queue if you starts to being rate limited by OpenAI. This service is smart enough to redirect the follow-up questions to the worker that handles the previous question.)

Usage

• The slackbot will listen to two types of event in slack workspace
  • Directly message the bot in slack.
  • Mention your bot in a channel with a question. For example: @ChatGPT BOT who is Donald trump?
• To ask follow up question, reply in the answer thread, otherwise it will treat it as a new question.
