Stack AI

What is Stack AI?

Stack AI is a no-code platform for building custom AI applications powered by Large Language Models. Teams can use it to create and deploy their own AI tools — similar to building a custom version of ChatGPT — directly into their products or services.

Typical use cases include customer-facing chatbots, document understanding tools, question-answering systems over databases, and content generation apps. The platform connects AI models with vector databases, external tools, and data loaders, so developers can integrate them without writing code. Data can be loaded from files, websites, and databases, and Stack AI connects with a wide range of other APIs. Models can also be fine-tuned to fit a product’s specific needs.

Ready-made templates are available for common tasks, so projects can start quickly. Data security is a stated priority, and companies like JustPaid, Smartasset, and Yummy use the platform. Stack AI is backed by investors including Soma Capital and Y Combinator, and AI workflows built on the platform can be exposed as APIs for easy integration.
