Slack Summarizer is a handy CLI tool for summarizing recent messages in Slack. It allows you to easily catch up on what's happening without leaving your command line.
To set up Slack Summarizer, start by creating a Slack app with the channels:history, channels:join, and channels:read scopes. Install the app to your workspace and make a note of the bot token. You'll need it when you first use Slack Summarizer. Now you'll need to get an OpenAI token from your preferred provider. If you choose to use a provider other than OpenAI itself, you'll have to change the default request URL and model name when using Slack Summarizer for the first time. You must ensure that the provider's API is OpenAI-compatible, or Slack Summarizer will be unable to use it.
When using this tool for the first time, you'll need to set a Slack bot token and OpenAI token. You can do this as below, replacing SLACK_TOKEN and OPENAI_TOKEN with the appropriate values:
slack-summarizer -s SLACK_TOKEN -o OPENAI_TOKEN summarize generalYou can also specify a different OpenAI API URL if you are using a different provider (e.g. Azure OpenAI, GitHub Models):
slack-summarizer -r API_URL summarize generalNote: The first run may take a long time, depending on your workspace size, as Slack Summarizer has to retrieve a list of all Slack channels and map channel names to IDs
