Build-Your-Own Custom Assistant

Difficulty: Advanced | Time to implement: 45 min | Saves you: ~5 hrs/week Tools: ChatGPT / Claude

Every prompt you have ever pasted started from zero. The model did not know your business name, what you sell, who buys it, what you charge, how you write, or what you would never say to a customer — so you typed some of that in, badly, and got an answer shaped by the half of the context you remembered to include. This template ends that. It builds a reusable custom assistant, a Custom GPT in ChatGPT or a Project in Claude, permanently loaded with a written brief of your business, so that every request afterward begins from a model that already knows. Built for owners who use AI most days and are tired of introducing their company to it every single time.
