Slack Message Patch is a Chrome extension designed to enhance the messaging experience on the web version of Slack. This tool allows users to review and edit their messages before sending them, utilizing a large language model (LLM) for proofreading. Key features include a quick shortcut for initiating corrections, the ability to compare original and revised texts side-by-side, and options for editing the corrected text directly. Additionally, users can register and switch between multiple presets for tailored corrections.

This extension is particularly beneficial for professionals looking to refine their business communications, streamline the editing process, and reduce the time spent crafting messages on Slack. To use Slack Message Patch, users need to input their OpenAI API key, type their message, and simply press Cmd + Enter (Mac) or Ctrl + Enter (Windows) to view suggested edits before sending.
