GPT3-slack is a Chrome extension developed by anchen that enhances your Slack web experience by providing grammar checking and text generation capabilities. With this extension, you can easily improve the quality of your messages and ensure they are error-free.

To get started, you need to obtain your API key from OpenAI's website and paste it into the extension. Once the key is saved, you can open Slack in your browser and start using the features. The extension adds two icons to the input box: a trencher cap for grammar correction and a light bulb for text generation.

What sets GPT3-slack apart is its utilization of the chatGPT model from OpenAI, which helps to reduce costs while maintaining the quality of the grammar checking and text generation. It's worth noting that there has been an update to the OpenAI policy, and data passed into the API cannot be used for model training.

Overall, GPT3-slack is a valuable tool for Slack users who want to improve their communication by ensuring grammatical accuracy and generating text effortlessly.
