Essential is an open-source MacOS application for developers. It captures the last 5 minutes of screen activity and leverages computer vision and OpenAI's LLMs to understand the content. Whether it's a build failure in your IDE, error logs and stack traces in the terminal or browser, simply switch to Essential and see solutions tailored to your environment. No more copying and pasting error messages to search for solutions or figuring out how to apply fixes in your setup! Essential also remembers your screen content. When reading or interacting with specific information, switching to the app will show you the most important screenshots and summaries for easy future reference. All of this happens entirely on your Mac, with no data leaving your system.
