A ChatGPT Slackbot

This is a very simple slackbot that uses the openAI API with chatGPT. It was put together in very little time with very little effort, so don't expect great things.

It currently uses the gpt-3.5-turbo model.

Setup your Slack Workspace

You will need to setup an app with Slack first. Go to api.slack.com/apps and create a new App.

Subscribe it to the following events:

app_mention - To respond to mentions
message.channels - To respond in Channels
message.groups - To respons in groups
message.im - To respond in private messages

It should have the following Scopes under "oauth & permissions":

app_mentions:read
channels:history
chat:write
groups:history
im:history
im:read

Write down your Slack App Token, Slack Bot Token and Slack Signing Secret. You will need those for the environment variables.

Setup the OpenAI API

Go to platform.openai.com/account/api-keys and create an API key. You will need that for the environment variable OPENAI_KEY.

Make it work

Create a .env file with the following content:

OPENAI_KEY=yourkeyhere
SLACK_APP_TOKEN=yourkeyhere
SLACK_BOT_TOKEN=yourkeyhere
SLACK_SIGNING_SECRET=yourkeyhere

Install dependencies:

pnpm i

Start the app:

pnpm start

Build for docker

docker build . -t thechadster

How to use it?

In slack, you can either add it to public or private channels, or you can talk to it in private messages.

In channels (public and private) it will only respond if you tag the bot user. It is necessary to invite the bot into the channel before this works. You can do that by doing /invite @botname.

In private messages with the bot, tagging is not necessary. It will respond to each message.

The bot will respond to you in the thread. If the message was a root-level message, it will create the thread. If you interact with the bot from a thread, the entire thread will be fed into chatGPT to give a more coherent response.

Using GPT-4

Add --v4 or --gpt4 to any of your messages and it will use gpt-4 to get an answer. By default it uses gpt-3.5-turbo.
