CalStudio, formerly Pmfm.ai, lets you create your own AI assistant or agent without writing code. Starter ideas include a study assistant, fitness coach, calorie tracker and travel planner, which you can adapt to your own niche.
Beyond single assistants, it offers Studios for grouping tools together and built-in options for charging users. It suits creators who want to turn their expertise into an AI product, and you can start on a free trial before upgrading.
