Slack Channel Summarizer

Video explanation (In Spanish): https://www.youtube.com/watch?v=u92bbYySLNM

This repository contains an implementation that allows users to obtain a summary of an entire Slack channel conversation by using the /summarize slash command. The implementation leverages OpenAI's API for text summarization and supports conversations of arbitrary length.

How it Works

When a user types the /summarize slash command in a Slack channel, the implementation retrieves the conversation history of that channel. It then sends the conversation text to OpenAI's API for summarization. The API processes the text and generates a concise summary of the conversation.

Prerequisites

Before using this implementation, ensure that you have the following prerequisites:

1. Slack API Token: You need a Slack API token with the necessary permissions to read conversation history and post messages in the desired channels. Obtain the token from the Slack API website.

2. OpenAI API Key: You must have an OpenAI API key to make requests to the text summarization API. Get your API key by signing up for an account on the OpenAI website.

3. Configure OpenAI Slash command: You need to configure the slash command /summarize/ in your OpenAI app with the required permissions, and obtain a public HTTPS URL, for example with ngrok.

Setup

Follow these steps to set up and run the Slack Channel Summarizer:

1. Clone this GitHub repository to your local machine.

2. Install the required dependencies by running the following command:

   npm install
   

3. Set the following environment variables in a .env file:

   • SLACK_API_TOKEN: Set this variable to your Slack API token.
   • OPENAI_API_KEY: Set this variable to your OpenAI API key.

4. Start the application by running the following command:

   npm run dev
   

Usage

To obtain a summary of a Slack channel conversation, follow these steps:

1. Join the desired Slack channel where you want to summarize the conversation.

2. In the channel, type the /summarize slash command.

3. Wait for a moment while the application retrieves and processes the conversation history.

4. The application will post a message in the channel containing a summary of the conversation.

Limitations

Please note the following limitations of the current implementation:

• The summarization quality depends on the accuracy and limitations of OpenAI's text summarization model.
• Very large conversations may take longer to process, depending on the length of the conversation and the available resources.
• The implementation may have rate limits imposed by the Slack API and OpenAI API. Ensure that you are aware of these limits to prevent any disruptions.
