PUCO — AI Launcher for macOS & iOS

PUCO started as a simple idea: working with AI prompts should feel fast, structured, and natural — not like digging through text files or Notion pages. The app combines a native macOS menu bar experience with an iOS companion app and focuses heavily on speed, usability, and real-world workflows for people who work with AI every day.

One of the core features is dynamic prompt templating. Prompts can contain variables that automatically turn into interactive form controls like dropdowns, sliders, or text inputs, making complex prompts reusable without editing raw text every time. On macOS, users can access everything through a global hotkey workflow designed around “Hotkey → Select → Fill → Copy → Done”.

The project includes a complete backend and website stack powering synchronization, SEO-friendly prompt pages, Open Graph previews, metadata handling, admin workflows, and API delivery for the apps. The architecture is intentionally pragmatic: native SwiftUI frontend apps combined with a FastAPI backend optimized for fast static API responses and low operational overhead.

A strong focus throughout the project was maintaining a privacy-first, local-first approach while still supporting seamless iCloud synchronization across Apple devices.
