HSX NanoCastify
Mirror your PC screen to a phone or TV
Screen mirroring and remote control for Windows. A viewer scans a QR code and your screen opens in their browser - no app to install, no account to create and no cloud service in the middle. Share one window or a whole monitor, hand over mouse and keyboard when you want to, and take control back instantly.
£13.99 on the Microsoft Store (UK), with a free trial firstPrice checked 10 October 2026. Prices differ by country; the Store shows yours.
Buy it once through the Microsoft Store. There is no renewal, and no account to keep it working: the copy on your machine keeps running whether or not this studio is still here. Genuine copies are sold only on the Microsoft Store.
What HSX NanoCastify does
- Viewers join by scanning a code - it opens in their browser, nothing to install
- Share a single window or a whole monitor, and switch displays mid-session
- Privacy pause freezes the broadcast behind a clean screen while you type a password
- Hand mouse and keyboard to an approved viewer, with a hotkey to take control straight back
- Spotlight, presenter pen, mouse halo and click ripples for showing rather than telling
- Record the session and system audio straight to your own PC
- PIN-locked rooms with a guest list you control, over Wi-Fi or your laptop hotspot

Your first hour with HSX NanoCastify
A short plan for getting to a real result while the trial is still running.
Start the free trial
Get HSX NanoCastify from the Microsoft Store. The Store page shows how long the trial lasts, so you know your window before you begin.
Use your own work
Try it on your own PC and real tasks rather than a quick look around. That is the only test that tells you whether it earns its place.

Decide before it ends
If it earned its place, buy it on the Microsoft Store before the trial runs out. The purchase unlocks the copy you already have, so there is nothing to reinstall.

Who it is for
HSX NanoCastify is built for editors, musicians and anyone who works with sound or footage and does not want it uploaded for processing.
It sits in the audio & video part of the catalogue, and your source files never leave the machine to be processed. There is no server behind HSX NanoCastify to send them to.
Local-first, by design
Plenty of the alternatives send your source files to a server to be handled. HSX NanoCastify does not. Processing runs on your CPU or GPU, and the projects you open stay where you put them. HSX NanoCastify does need your devices to be on the same network, but that is the only link involved: it runs over your own Wi-Fi or a hotspot, with nothing routed through a server and no internet connection required.
That is not a setting you enable, it is how HSX NanoCastify is built, which is why there is no account to create and no subscription to lapse. Full detail is in the HSX NanoCastify privacy policy.

Does HSX NanoCastify require an account?
No. There is no registration, no sign-in and no online identity. You install the application and use it.
What data does HSX NanoCastify collect?
None. There is no analytics, no usage tracking and no crash reporting that leaves your device, and your source files are never uploaded. The full detail is in the HSX NanoCastify privacy policy.
Is HSX NanoCastify a subscription?
No. HSX NanoCastify is a free trial followed by a one-time purchase through the Microsoft Store. There is no recurring fee.
