Gen AI can save you time, but once you’re using it frequently, the process of repeatedly uploading the same background files and re-entering prompts for common tasks can really eat into your efficiency gains. That’s why many generative AI platforms allow you to create custom AI assistants: what ChatGPT calls a “custom GPT,” Claude calls a “Project,” and Google Gemini calls a “Gem.” These assistants store elements of a prompt that you might want to use over and over so you don’t have to include them every time you ask the platform to help you with your recurring tasks and challenges.
