Alterego presents the first “almost telepathic” device that promises to write at the speed of thought

The boundary between mind and machine has just made a historic leap. The startup Alterego, born from research at MIT, has publicly unveiled what it describes as the world’s first “almost telepathic” wearable device, capable of enabling silent communication, hands-free application control, and writing at the speed of thought.


A step further in human-machine interface

The system, named Silent Sense, does not read private thoughts but detects the subtle signals the brain sends to the vocal apparatus before uttering words. Technically, this is known as “silent speech.” Alterego takes it further by recognizing not only spoken words but also those that are murmured, articulated silently, or even remain as internal intent.

With this technology, the founders assure that interaction with artificial intelligence becomes a natural extension of the human brain.


What Alterego enables

The company has broken down some of the main capabilities of the wearable:

  • Writing at the speed of thought, without a keyboard.
  • Restoring speech capability for people with disabilities.
  • Silently searching the internet.
  • Controlling apps and devices hands-free.
  • Asking questions about the environment via integrated micro-cameras.
  • Maintaining private, silent conversations with other users.
  • Collaborating with AI in a more fluid and natural way.

In initial demonstrations, CEO Arnav Kapur showed how he sent messages without speaking, set reminders on a mobile device, and even held silent conversations with a colleague using two synchronized devices.


A revolution for accessibility

Apart from technological impact, Alterego presents a concrete hope for millions of people with communication issues. Its ability to interpret the intention to speak opens the door to returning language to those who have lost it due to illness or accident.

Indeed, the company emphasizes this potential as one of its core pillars: technology not only as a productivity shortcut but as a tool for social inclusion and personal autonomy.


Context: from Neuralink to non-invasive interfaces

In recent years, neurotechnology projects have garnered headlines—from brain implants like Neuralink to experimental interfaces in laboratories. However, Alterego emphasizes a key difference: its wearable does not require surgery or invasive connections, reducing barriers to adoption and associated risks.

“For the first time, thought-speed communication can reach the market without surgery,” say the company.


Founders with backgrounds in neuroscience and technology

The project is led by two well-known figures in the field:

  • Arnav Kapur, CEO and co-founder. A pioneer of silent speech interfaces at MIT Media Lab, he has been awarded the TIME Best Inventions and the Lemelson-MIT Graduate Prize, among other honors.
  • Max Newlon, COO and co-founder. Former president of BrainCo, where he took a neurotech startup from laboratory to unicorn, with products applied in health, education, and medicine.

They combine scientific and business expertise with a vision focused on enhancing human development through technology.


A new era without keyboards or screens

Alterego frames its approach as a paradigm shift: overcoming dependence on keyboards, touchscreens, and voice commands. According to the company, these interfaces have slowed down how we interact with information for decades.

The promise is frictionless communication, where intent translates directly into action. This opens the door to new ways of working, learning, and collaborating with AI systems.


Challenges and cautions

While the demonstration has generated enthusiasm, voices calling for caution are not lacking. Many recall that recent history is full of AI and neurotechnology projects that failed to meet initial expectations.

Aspects such as the device’s accuracy, its long-term comfort, and privacy of collected data will be crucial in determining whether Alterego is a revolutionary leap or just another promise in a highly complex field.

The company itself insists that its device “never reads your thoughts” and only interprets what the user consciously tries to say.


A future of human-AI collaboration

In the words of its founders, Alterego is not just a tool but a step toward the full integration of artificial intelligence as an extension of the human mind. The vision is ambitious: humans and machines collaborating in real time, at the speed of thought.

The device already has a waitlist for early access on its official website, marking the beginning of a path that could radically transform the relationship between brain and technology.


Frequently Asked Questions (FAQs)

What exactly is Alterego?
It is a non-invasive wearable device that enables communication and control of technology by detecting brain signals sent to the speech system before words are spoken.

How does it differ from Neuralink or other implants?
Alterego requires no surgery or implants. It operates externally, worn around the head and ears, making it safer and more accessible.

Can Alterego read private thoughts?
No. The company emphasizes that it only interprets what the user consciously tries to say, avoiding access to involuntary thoughts.

What practical applications does this wearable have?
From restoring communication for people with disabilities to writing without a keyboard, silent internet searching, or controlling devices hands-free, and opening new ways of human-AI collaboration.
