Sightful’s Spacetop for Windows is rapidly redefining what we think of as a productivity setup. Instead of being tethered to a single monitor or juggling multiple windows on a small laptop screen, users can now immerse themselves in an augmented reality workspace that feels as close to the future as we have seen outside of a sci-fi movie. The concept is simple yet powerful: pair a set of XREAL Air 2 Ultra AR glasses with the Spacetop software running on a compatible Windows AI PC, and you unlock a sprawling virtual desktop that surrounds you.

Sightful first showed off a version of this technology back in early 2023, when it debuted a headless laptop prototype. That earlier device used a Chromium-based system and a custom hardware form factor. It was promising, but the industry’s rapid shift toward AI PCs—powerful laptops equipped with Intel Core Ultra processors and ample memory—prompted Sightful to completely rethink its approach. The result is Spacetop for Windows, a pure software solution that leverages the horsepower of any compatible laptop rather than requiring proprietary hardware.

Setting up the Spacetop is straightforward. After unboxing the XREAL Air 2 Ultra glasses and downloading the Spacetop app, users simply log in and pair the glasses via USB-C. The glasses are lightweight, comfortable, and come with prescription lens inserts as an option. Once connected, the Windows desktop extends into a massive virtual canvas. You can place windows anywhere around you—above, below, and to the sides—effectively turning your physical environment into a multi-monitor command center. The six-degrees-of-freedom tracking feels natural, and the 1080p-per-eye OLED display is crisp enough for text work, coding, and media consumption.

Spacetop for Windows is the most practical spatial computing product I have used. It doesn’t try to replace your laptop—it augments it in a way that makes immediate sense.

Of course, the experience has some rough edges. The software is still maturing, and some users have reported occasional bugs, such as windows drifting or the virtual display briefly disconnecting. Sightful is actively pushing updates, and the community is growing, but these early issues are worth noting. Battery life also takes a hit—driving the AR glasses alongside the laptop display consumes more power than a standard workflow. The subscription model, at $200 per year after the first free year, adds an ongoing cost that may give some users pause. Still, for anyone who works across multiple screens while traveling, the convenience is hard to overstate.

Laptop compatibility is currently limited to Intel-based AI PCs with Core Ultra 7 or 9 processors and at least 16 GB of RAM. Sightful has published a list of recommended models including the Dell XPS, Lenovo Yoga Slim 7i, and Asus Zenbook S 14. There is no support for AMD or Qualcomm chips at launch, though Sightful has indicated it may expand compatibility over time. A Mac version is also in the works, likely arriving in 2026. This selective compatibility is a temporary limitation, but one that early adopters need to plan around.

What makes the Spacetop compelling beyond the hardware specs is how it changes the way you think about your workspace. In a coffee shop, on a plane, or at a co-working desk, you suddenly have the real estate of a triple-monitor setup without physically carrying anything extra. The AR overlay is transparent enough that you remain aware of your surroundings, which is a safety advantage over fully immersive VR headsets. You can glance over the top of the glasses to see your keyboard, grab a drink, or talk to someone without removing the headset.

Sightful has succeeded where many others have stumbled by focusing on a single, well-defined use case: productivity. Rather than trying to be a gaming platform, a media device, and a virtual reality headset all at once, Spacetop for Windows is laser-focused on giving you more screen real estate wherever you go. For digital nomads, remote workers, and anyone who spends significant time away from a fixed desk, this focus pays off. The subscription price is a consideration, but the hardware—the XREAL glasses—is yours to keep, and the software is actively improving with each update.

How Spacetop Compares to the Competition

Apple’s Vision Pro offers a more immersive experience with eye-tracking and passthrough video, but at a much higher price point and a bulkier form factor. The XREAL Air 2 Ultra glasses that ship with Spacetop are significantly lighter and more socially acceptable in public settings. Competitors like the XREAL Beam and the Viture Pro neckband offer screen mirroring, but none deliver the same deep Windows integration that Spacetop provides. What sets Spacetop apart is the software layer: proper window management, a floating taskbar, and the ability to treat AR windows like real monitor extensions. It is not perfect, but it is the first product in this category that feels genuinely useful for daily work.

The bottom line is this: Spacetop for Windows is a genuine leap forward for spatial computing productivity. It solves the real-world problem of limited screen real estate on the go, and it does so with minimal friction. Early bugs aside, the core experience is impressive. If you need a mobile multi-monitor workflow and own a compatible AI PC, the Spacetop bundle is worth a serious look. The future of mobile productivity is not about bigger laptop screens—it is about eliminating the laptop screen entirely.
