If you don't like Riku, there are plenty of other contenders worth considering that let you build and run AI apps without writing any code.
One is Rubber, a no-code platform for building apps that use AI for lead generation, customer service and validating product ideas. It's got a library of prebuilt blocks and the ability to create your own user interface, integrate with ChatGPT and link to different data sources. Rubber's plans range from a free Personal tier to a $30/month Pro tier, so it should be within reach of most people.
Another strong contender is Imagica, a no-code tool that lets you build working AI apps by describing what you want them to do in plain language. Imagica is designed to be easy to use and to integrate with trusted data sources, so it's good for areas like finance, education and marketing. It's got support for multimodal input and output formats, the ability to generate images, and a way to monetize your results.
If you're more of a power user, UBOS is an all-purpose, low-code foundation that can be used to build your own custom Generative AI and AI apps. It can be set up with a single click on any cloud computing foundation and can run models like ChatGPT and Llama 2, so it's good for startups and enterprises.
