After several months of development, I'm releasing the **Developer Preview** of **Shree AI OS**, a Java-first AI runtime designed for building intelligent backend applications.

Most AI frameworks focus on chatbots. My goal was different: create a reusable runtime that developers can embed directly into Java applications with memory, planning, reasoning, and hybrid retrieval.

While building Spring Boot applications, I found that adding AI often meant stitching together multiple services. I wanted a deterministic runtime that provides:

The platform follows a layered architecture:

Every request flows through an explainable cognitive pipeline instead of directly calling an LLM.

I also built an official documentation website using **Next.js 16**, **React 19**, **Tailwind CSS 4**, and **Framer Motion**.

It includes:

This is still a **Developer Preview**, and I'd love feedback from Java and backend developers.
