Question: I'm looking for a platform that allows me to build AI applications using pre-trained language models without needing to be a programmer.

If you want to build AI apps using pre-trained language models without having to write any code, Rubber is a good choice. This no-code platform lets you build AI-powered apps for lead generation, customer support and other tasks. It's got a library of building blocks and the ability to string prompts together for more elaborate workflows. You can use big AI models like GPT-4 without worrying about integration, and there are 30+ professionally designed templates to get you started.

Another good choice is Riku, which also offers a no-code environment for building, testing and deploying AI apps. It supports more than 40 large language models and lets you quickly create chat, text and image apps. You can try different prompts and models, deploy to different environments, and integrate with other tools for automation. Riku offers a 5-day free trial and two pricing tiers depending on your needs.

For an open-source option, LLMStack is a flexible platform that lets you build generative AI apps, chatbots and agents using pre-trained models. It includes a no-code builder for connecting multiple LLMs to data and business processes without requiring programming knowledge. LLMStack can import data files in a variety of formats and includes features like vector databases and multi-tenancy controls, making it suitable for both cloud and on-premise use.

Last, if you want to build your own custom AI tools and automations without writing any code, check out MindStudio. The platform lets you build no-code AI apps, personalized AI assistants and integrate with a variety of data sources. Tiered pricing plans mean you can pick the one that works best for you, and you only pay for the AI models you use. Each model's price ranges from $0.33 to $36.00 per 1 million tokens.
