LogicSage

Want a customizable, open-source GPT chat app you can actually look under the hood of? LogicSage is a SwiftUI app and Swift Vapor server built for chatting with GPT models on iPhone and iPad — and it doesn't hide anything from you.

Features include chat history saved to disk, haptic feedback, customizable colors and text sizes, and — uniquely — the ability to generate Xcode projects with GPT using Logic Sage for Mac. Because it's open-source, you can inspect, fork, and build on it however you like. Available on the App Store, it's the GPT chat client for developers who want transparency and flexibility, not just convenience.
