NextMind was a real $399 non-invasive brain-computer-interface developer kit launched in 2020, but it is no longer a normal supported product. Snap acquired NextMind on March 23, 2022, and the standalone kit effectively ended. In 2026, treat any unit as legacy hardware: its value depends on whether you can obtain the original SDK, drivers and activation software.
What the NextMind Dev Kit was
NextMind was a Paris-based neurotechnology company building hands-free interfaces for computers, games and augmented- or virtual-reality systems. Its development kit combined three elements:
| # | Preview | Product | Price | |
|---|---|---|---|---|

Information Disorder: Algorithms and Society | $27.54 | Buy on Amazon |
- NextMind Sensor: a wearable brain-sensing device positioned at the back of the head.
- NextMind Engine: real-time machine-learning software that interpreted signals from the sensor.
- NextMind SDK: Unity-oriented tools, tutorials, demonstrations, games and code components for developers.
The launch description and original component list are documented by NextMind’s 2020 announcement.
This was not an implanted medical device or a general-purpose mind-reading system. It was a constrained interaction technology designed to recognize neural activity associated with visual attention.

How the interaction worked
- The application presented a specially designed visual target, such as a button or game element.
- The user focused attention on that target.
- The sensor recorded neural activity associated with processing the visual stimulus.
- The NextMind Engine classified the signal.
- The application converted the result into an action, such as selecting the button.
Snap described the experience as letting a user “push a virtual button” by focusing on it. Snap also explicitly said the technology did not read thoughts or send signals into the brain; see its NextMind acquisition announcement.
“Real-time” described the processing and interaction loop, not guaranteed instantaneous or error-free control. Results could vary with fit, movement, hair, muscle and eye activity, fatigue, attention, visual-stimulus design and calibration.
Not the same as eye tracking
- Eye tracking measures where the eyes are directed.
- NextMind-style visual BCI attempts to detect neural responses associated with attention to a designed visual target.
- A controller supplies explicit physical input.
- A research EEG system generally exposes broader biosignal data for analysis.
A NextMind interaction could feel similar to gaze selection, but the device was not simply an eye tracker.
What came in the original kit
Launch and shipping materials identified the following contents:
- Brain-sensing wearable sensor
- Adjustable headband
- USB-C cable
- Real-time machine-learning engine
- Unity SDK
- Tutorials, demo applications and games
- Reusable code building blocks
The sensor was presented for use on its own, with an AR or VR headset, or alongside conventional controllers such as a gamepad. The December 2020 shipping announcement describes the developer software and intended configurations.
Price, launch timeline and originally advertised compatibility
| Item | Historical information | 2026 qualification |
|---|---|---|
| Public price | $399 | Original launch price, not a current verified retail price |
| CES exposure | January 2020 | Early product publicity and award attention |
| Commercial availability | Public preorders in 2020 | Do not infer current availability |
| Shipping announcement | December 2020 | Historical shipping milestone |
| Acquisition | Snap announced the acquisition on March 23, 2022 | NextMind joined Snap Lab for long-term AR research |
The original shipping material listed compatibility with Windows 10, macOS, Oculus, HTC Vive and Microsoft HoloLens, plus Unity workflows. Those were period claims, not confirmation of support for Windows 11, current macOS releases, Apple Silicon, modern Unity versions or today’s XR runtimes. The original price and platform list come from NextMind’s shipping release.
What happened after Snap acquired NextMind
Snap said the NextMind team would join Snap Lab, its long-term augmented-reality research group. Contemporary reporting described the acquisition as ending the Dev Kit as a standalone product; see TechCrunch’s March 23, 2022 report.
Snap’s current developer pages list active products such as Camera Kit, Creative Kit and Login Kit, but do not present NextMind as a current public hardware or SDK product. Check Snap’s SDK downloads and its API overview before assuming any legacy package is still supported.
Can you still buy or use NextMind in 2026?
There is no verified active first-party purchase path. A marketplace unit may be genuine yet unusable if the SDK, drivers, account service or activation path is unavailable. Hardware photographs and a claim that a unit is “untested” do not establish that it can run.
Checks before buying a used unit
- Confirm the sensor, headband, USB-C cable and any required accessories are included.
- Ask whether the original SDK and companion software can be obtained legally.
- Identify the exact archived Unity and operating-system versions required.
- Check whether drivers work on your intended computer, including Apple Silicon or current Windows systems.
- Determine whether activation or cloud services are still required.
- Request proof of operation and a meaningful return policy.
- Inspect the sensor for worn or damaged contact surfaces and verify firmware information.
“New old stock” should be treated as a hardware purchase with uncertain software value. The original product’s privacy terms may also be unavailable or outdated; with unofficial software, establish where neural data is processed, stored, transmitted and logged.

Reasonable historical use cases
- Experimental games and interactive installations
- XR interface prototypes
- Hands-free selection demonstrations
- Accessibility research prototypes
- Teaching or demonstrating attention-based BCI concepts
Poor fits
- Raw EEG research requiring broad channel access
- Motor-imagery BCI experiments
- Clinical diagnosis or treatment
- Safety-critical or mission-critical control
- Commercial products that require an active vendor and stable supply chain
- Systems claiming arbitrary speech, memory or thought decoding
The device was non-invasive: it sensed externally and did not transmit signals into the brain. That does not make it a medical device, a validated assistive technology or a replacement for established eye tracking, switch access, speech input or adaptive controllers. Individual users may obtain unreliable signals or find sustained visual attention unsuitable.
Current alternatives by project goal
| Goal | Option | What it offers | Important limitation |
|---|---|---|---|
| Supported neurotechnology research | Kernel DevKit-3 | Developer-oriented fNIRS systems with EEG components, acquisition software and SDK access; listed price $15,600 plus taxes and shipping | Research infrastructure, not a low-cost visual-attention controller |
| Higher-capability research platform | Kernel DevKit-12 | Listed price $46,500 plus taxes and shipping, with configurable research hardware and cloud plans | Far more expensive than NextMind; confirm current subscription terms |
| Custom biosignal development | NexiMind NxBCI | Described as a 16-channel EEG/EMG acquisition system with configurable output and expansion interfaces | Price not stated; requires your own signal-processing work |
| Emerging developer headset | Kyma | Modular headset and developer kit planned for Winter 2026, initially for 150 builders, developers and researchers | Early-access product; public price not stated |
| Production hands-free interaction | Eye tracking, hand tracking, voice, switches or conventional controllers | Often easier to support and deploy than a legacy BCI | These are not neural-signal interfaces |
These options are not interchangeable. Kernel is aimed at formal research, NxBCI at configurable biosignal acquisition, and Kyma at an emerging developer ecosystem. If the actual requirement is reliable hands-free XR input, a non-neural method may be the better engineering choice.

NextMind remains technically interesting as an early commercial visual-attention BCI: a user focused on a designed target, the system interpreted the associated neural response, and software triggered an action. But the $399 kit belongs to the 2020–2022 product era. Following Snap’s acquisition, it is no longer presented as a current standalone developer platform.
Do not plan a new production project around NextMind. Investigate it only if you already own compatible hardware and can verify lawful access to the legacy software stack. For new work, choose a supported research platform, a modular EEG/EMG system, an emerging developer kit after due diligence, or a conventional hands-free input method.
