Abstract: Quantum optimal-control methods routinely outperform analytic shaped pulses for broadband and band-selective spin manipulation and coherence transfer, and can be made robust to instrumental limitations, B_0/B_1 inhomogeneity, and relaxation. Yet their adoption remains limited by a steep tooling barrier, i.e. designing pulse shapes requires installing a scientific programming environment, learning a package API, and writing scripts by hand. We present Pulsar Studio, a cross-platform desktop application that removes this barrier by wrapping the Pulsar.jl optimal-control library behind a guided graphical interface. Crucially, end users need no programming environment and write no code. The application bundles its own Julia runtime and optimization backend, so spectroscopists install a single package and begin designing pulses immediately. During optimization, the interface streams live diagnostics — fidelity convergence, gradient norm, and an updating waveform snapshot — allowing users to judge and cancel runs interactively. Designed pulses can be exported directly to the instrument-ready formats supported by Pulsar.jl. The complete experiment — system definition, constraints, and run history — are saved as portable project files, supporting reproducible and shareable workflows. By making quantum optimal-control pulse design approachable without any coding, Pulsar Studio lowers the barrier for adapting robust pulse engineering into everyday magnetic-resonance practice.
