Embedchain Examples Repo contains code on how to build your own Slack AI to chat with the unstructured data lying in your slack channels.

​
Getting started

Create a Slack AI involves 3 steps

  • Create slack user
  • Set environment variables
  • Run the app locally

​
Step 1: Create Slack user token

Follow the steps given below to fetch your slack user token to get data through Slack APIs:

  1. Create a workspace on Slack if you don’t have one already by clicking here.

  2. Create a new App on your Slack account by going here.

  3. Select From Scratch, then enter the App Name and select your workspace.

  4. Navigate to OAuth & Permissions tab from the left sidebar and go to the scopes section. Add the following scopes under User Token Scopes:

    # Following scopes are needed for reading channel history
channels:history
channels:read

# Following scopes are needed to fetch list of channels from slack
groups:read
mpim:read
im:read

  5. Click on the Install to Workspace button under OAuth Tokens for Your Workspace section in the same page and install the app in your slack workspace.

  6. After installing the app you will see the User OAuth Token, save that token as you will need to configure it as SLACK_USER_TOKEN for this demo.

​
Step 2: Set environment variables

Navigate to api folder and set your HUGGINGFACE_ACCESS_TOKEN and SLACK_USER_TOKEN in .env.example file. Then rename the .env.example file to .env.

By default, we use Mixtral model from Hugging Face. However, if you prefer to use OpenAI model, then set OPENAI_API_KEY instead of HUGGINGFACE_ACCESS_TOKEN along with SLACK_USER_TOKEN in .env file, and update the code in api/utils/app.py file to use OpenAI model instead of Hugging Face model.

​
Step 3: Run app locally

Follow the instructions given below to run app locally based on your development setup (with docker or without docker):

​
With docker

docker-compose build
ec start --docker

​
Without docker

ec install-reqs
ec start

Finally, you will have the Slack AI frontend running on http://localhost:3000. You can also access the REST APIs on http://localhost:8000.
