Couponly
couponly.ai
Couponly AI is an AI-powered shopping assistant and browser extension that takes the manual work out of finding discounts. When you reach a checkout page, Couponly automatically detects the promo code field, tests available codes against your actual cart in real time, and applies the one that works best — no more searching coupon sites or pasting expired codes one by one. Unlike traditional coupon tools that only support a fixed list of major retailers, Couponly uses AI to recognize checkout pages across stores of all sizes, so it works on independent shops as well as big-name brands. Codes are verified live at the moment of purchase, meaning you get a working result instead of a list of maybes. Available for Chrome, Firefox, and Microsoft Edge, with iOS and Android apps in development. Upcoming features include item saving, price tracking, price history, cashback, and smarter deal alerts.

BootCampARM
bootcamparm.com
BootCampARM is an experimental open-source project working to bring native Windows 11 ARM64 boot capabilities to Apple Silicon Macs. Inspired by Apple’s original Boot Camp for Intel-based Macs, BootCampARM aims to make it possible to install and boot Windows directly on Apple Silicon hardware without relying on traditional desktop virtualization software. At its core is BootCampKit, a Swift-based installation and firmware orchestration framework designed to automate the complex process of preparing storage partitions, configuring Apple’s secure boot environment, deploying Windows installation media, and integrating ARM64 bootloaders. The project builds on technologies including m1n1, U-Boot, UEFI, and ARM exception-level virtualization, with the long-term goal of supporting multiple Apple Silicon generations, from M1 onward. Current development status: Active research and development. Initial work on the M3 MacBook Pro has demonstrated execution of custom UEFI applications and diagnostic interactions with Microsoft Windows ARM64 boot components. A complete, functional Windows installation has not yet been achieved. BootCampARM’s long-term vision is to make Windows on Apple Silicon more accessible, reproducible, and maintainable through open-source collaboration. Built for developers, hardware enthusiasts, and anyone interested in the future of operating systems on Apple Silicon.
