Harvard Graduate Creates $1,200 Device to Block AI Wearables From Recording Your Conversations

2026-03-07 data

Cambridge, Saturday, 7 March 2026.
A Harvard graduate has developed the Spectre I, a portable jamming device that promises to make your conversations unrecordable by nearby AI wearables and smart devices. The $1,200 tabletop orb uses ultrasonic frequencies and AI to detect microphones and scramble audio recordings within range. While the March 2026 announcement went viral with over 3.6 million views, experts remain skeptical about its technical feasibility, citing fundamental physics limitations that may prevent the device from working as advertised.

The Inventor and Her Mission

Aida Baradari, the founder of Deveillance and a recent Harvard graduate, developed the Spectre I as a response to the proliferation of always-listening devices in everyday life [1]. Baradari announced the device on March 1, 2026, through a video posted on X (formerly Twitter) on March 3, which quickly gained over 3.6 million views [2][3]. “People should have a choice over what they want to share, especially in conversations,” Baradari explained. “If we can’t converse anymore without feeling scared of saying something that’s potentially taken out of context or wrong, then how are we going to build human connection in this new age?” [1]. The timing of the announcement coincides with growing consumer anxiety about pervasive recording devices, highlighted by Ring’s controversial Super Bowl commercial in February 2026 that led to public backlash and the cancellation of a partnership with Flock Safety [1].

Technical Specifications and Claims

The Spectre I is designed as a dome-shaped tabletop device about the size of a small Bluetooth speaker, featuring a power button, indicator lights, and a central activation button [4]. According to Deveillance, the device “emits an inaudible signal that makes every microphone within range unable to capture intelligible audio” by generating an ultrasonic “fog” to confuse nearby microphones [2][4]. The system combines ultrasonic frequency emitters with AI and signal processing technology to detect and log nearby microphones using RF and Bluetooth low energy detection methods [1][2]. Baradari claims the device uses “AI and novel physics research to make jamming targeted, smart, and portable,” distinguishing it from traditional high-power jammers [6]. The device is currently available for pre-order at $1,199, with limited-time discounts of 20% to 30% available, bringing the price down to as low as $839.99 [2][3][4].

Market Context and Consumer Demand

The Spectre I addresses a significant market concern, as research from Digital Third Coast in 2023 found that 60% of over 800 surveyed Americans believed their phones were eavesdropping on them, with this figure rising to 74% among Amazon Alexa owners [3]. Deloitte’s Connectivity and Mobile Trends research indicates that U.S. households now have an average of two dozen connected devices, many equipped with always-listening features [2]. The device specifically targets newer AI wearables such as the Bee AI bracelet and the Friend pendant, which represent the latest generation of always-on recording devices [1]. “Smart devices and AI recorders are all around us, collecting our conversations and turning them into data,” Baradari stated. “It’s not just about privacy anymore. This is about freedom” [3].

Expert Skepticism and Technical Challenges

Despite the viral attention, technical experts have raised significant doubts about the Spectre I’s capabilities. Dave Jones, an engineer and YouTuber, criticized the device’s claims, stating: “They simply cannot do this. They are using the classic trick of using wording to imply that it will detect every type of microphone, when all they are probably doing is scanning for Bluetooth audio devices” [1]. John Scott-Railton, a cybersecurity researcher at Citizen Lab, questioned the claims about the device’s “AI and novel physics,” noting: “This would be extraordinary and would require equally extraordinary proof if true” [3]. When WIRED requested proof of the device’s ability to identify and block microphones, the shared video clips were deemed unconvincing [1]. The fundamental challenge lies in physics limitations, as many microphones that users are most concerned about don’t emit WiFi or Bluetooth signals, or could be phones in airplane mode, making detection nearly impossible [1][3].

Deveillance expects to begin shipping the Spectre I in the second half of 2026, with August as the target month [1][4]. The company acknowledges that the device is still in early development with a substantial lead time [2]. Beyond technical challenges, legal questions surround the device’s operation, as the legality of acoustic jamming remains uncertain, unlike radio jamming which is explicitly prohibited by the FCC and broadly illegal in many countries [2]. Additional concerns exist regarding the potential effects of ultrasonic frequencies on humans and pets, areas that require third-party evaluation [2]. Cooper Quintin, senior staff technologist at the Electronic Frontier Foundation, offered measured support: “If this technology works, it could be a boon for many. It is nice to see a company creating something to protect privacy instead of working on new and creative ways to extract data from us” [1]. However, the device’s limitations are significant—it focuses solely on acoustic eavesdropping and will not stop cameras, keystroke loggers, or metadata collection [2].
