deanham / gpt-slack

A ChatGPT Slack integration using Slack's Bolt framework

GPT-Slack

A slack bot that proxies messages out to OpenAI's ChatGPT API.

Running

A Dockerfile is provided to bundle up the application, if Heroku is not an option for you.

Configuration

To easily create the Slack app, use slack-manifest-template.yaml in the "create new apps" page on Slack. Make sure to update the event subscription URL once the gpt-slack application is deployed.

Environment variables:

• SLACK_BOT_TOKEN: Obtain this (and the other slack variables) from the Slack Bolt JS getting started guide.
• SLACK_SIGNING_SECRET
• SLACK_APP_TOKEN: If an app token is provided, the application will run in "socket mode," and will not need to have an incoming request URL configured. Only set this value if you intend to run in socket mode. Attempting to do a webhook event subscription with this value set may fail.
• OPENAI_API_KEY: Obtain this from OpenAI

Required Slack permissions:

• app_mentions:read: Allow the bot to be invoked by an @-mention
• chat:write: Allow the bot to write responses
• channels:history: Allow the bot to read threads to provide context to ChatGPT
• groups:history: Allow the bot to read threads to provide context to ChatGPT
• im:history: Allow the bot to read threads to provide context to ChatGPT
• mpim:history: Allow the bot to read threads to provide context to ChatGPT

Additional required setup:

• Configure the Slack app's event request URL to be https://<deployed-app-url>/slack/events
• Add an event subscription for app_mention to the bot app under "event subscriptions" in Slack's developer portal

Usage

In a Slack channel, write a message @-mentioning the bot.

@gptbot, implement hello world in Elixir

The bot will respond to the message in a thread with "Thinking…"

After there is a response from OpenAI, the "Thinking…" message will be replaced with the response.

System prompts

Any message containing [SYSTEM] will be interpreted as a system prompt, which is used to provide instructions to ChatGPT.
