Building custom GPTs has never been easier like this before OpenAI released GPTs and Assistants. Although OpenAI’s Dev Day — nicknamed Red Wedding — killed thousands of startups, it introduced tons of opportunities to people at the same time.

Let me introduce you to connect your custom GPT to your Slack workspace. If you haven’t made one, check “How To Create Your Own Custom GPT: Beginner’s Complete Guide”.

How it Works

Before we jump into the integration, let me explain how it works:

  1. Build a custom GPT using OpenAI GPTs. We assume that you have already made one.
  2. Convert the custom GPT to an OpenAI Assistant so that Slack can send API requests to it.
  3. Connect the OpenAI Assistant with Slack workspace using PlugBear.

Simple, isn’t it? Let’s dive in.

1. Importing custom GPTs to PlugBear

OpenAI’s GPTs and Assistant are similar. Although there are small differences, most configurations can be interchangeable.

Using PlugBear, you can easily convert your custom GPTs to OpenAI Assistants so that you can use them in your daily tools like Slack or Zendesk.

  1. Sign up for
  2. Visit the “LLM Apps” page.
  3. Add the PlugBear bookmark to your bookmark bar.
  4. Open your custom GPTs and click the bookmark.

2. Integrating it into your Slack Workspace

PlugBear is a great no-code tool for connecting the GPTs/Assistant and Slack.

Follow these simple steps:

  1. Add your Slack workspace from the Channels page.
  2. Open the Connections page, click the “New Connections” button, and select your Slack workspace and the Assistant to connect them.

All Done! Check the “Connecting the OpenAI Assistant to Slack with PlugBear” post if you need a more detailed guide with screenshots.

3. Having Fun

Invite @PlugBear to your Slack channel and ask the bot questions with a mention. Your custom GPTs will get the query and give you an answer using the Slack thread.
