LogicSage: Open-Source Mobile GPT Coding App
LogicSage turns your iPhone or iPad into a mobile AI coding workspace, letting you chat with GPT, generate Xcode projects, and manage Git repos on the go.
Overview
LogicSage is a free, open-source SwiftUI application paired with a Swift Vapor backend that brings the power of GPT models directly to your mobile device. Designed for developers who want to code and converse with AI without being tethered to a desktop, it offers a fully customizable chat experience complete with saved history, haptic feedback, and adjustable colors and text sizes. Beyond simple conversation, LogicSage stands out by allowing users to generate entire Xcode projects through AI prompts using its companion Mac tool, Logic Sage.
The app goes further than typical chat wrappers by integrating real development workflows: users can download Git repositories, view syntax-highlighted and color-customizable code, and even push pull requests directly from the interface. With the ability to switch models mid-conversation and rely on built-in or custom system messages, LogicSage adapts to a variety of coding and brainstorming needs. Since it's fully open-source, developers can inspect, modify, or contribute to the codebase on GitHub, making it a transparent and community-friendly alternative to closed AI coding assistants.
