What are Choteri macOS menu bar utilities?

Choteri develops native, lightweight utilities designed exclusively for the macOS menu bar, including Numsy (floating tape calculator), Prompty (instant AI prompt manager), and Converty (live menu bar currency converter). Unlike electron-based background tools, each utility is engineered in pure Swift and SwiftUI to ensure near-zero CPU footprint, negligible memory usage, and instant startup times. All data processing, OCR text scanning, calculation history, and personal prompts remain strictly on-device, honoring complete user privacy with zero cloud telemetry or tracking. Built as universal binaries optimized for Apple Silicon M1 through M4 architectures as well as Intel hardware, every application is digitally signed and notarized by Apple for verifiable security and sandboxed reliability. By replacing bulky multi-window applications with focused, global keyboard shortcuts in the status bar, Choteri streamlines daily productivity for developers, designers, writers, and power users who value speed, craftsmanship, and local execution.
