I wrote a step-by-step tutorial showing how to build a local ChatGPT-style desktop app using Tauri (UI) and Deeb (embedded JSON persistence). The guide covers:

- bootstrapping a Tauri + React app - adding Tailwind + DaisyUI for quick UI - modeling and persisting chat messages with Deeb - wiring Tauri commands for saving messages and calling OpenAI

Why this approach: keep conversations local, avoid vendor lock-in, and learn Rust + desktop dev. The post includes a full example and a repo with source code.

Happy to answer questions about the architecture, persistence choices, streaming implementation, or packaging for Linux/Windows/macOS.
