Subvocal opens preorders for silent-input glasses. They read mouth movement, with no camera
The Subvocal Company, YC F26. Glasses that turn silent mouth movement into text. US preorders, a $199 deposit, $499 early, with shipping expected in Q1 2027.
The Subvocal Company has opened preorders for glasses that type without speaking. Founder Aarush Yadav announced it on X on 30 October 2026, and the YC Launch page carries the same account. Funding is about $1.3 million, including Y Combinator and Afore Capital.
What it does
Move your mouth without sound, and that movement becomes text. In the company’s wording, low-power radio (RF sensing) is aimed at the face, and a model turns the reflections that change with muscle movement into text. It does not pick up a voice with a microphone. The official page writes that a camera is not needed either. The positioning is that this is not video input for lip reading.
The speed claim is more than 200 words per minute. In the demo video, an instruction for an email draft or a Slack summary appears on screen from mouth movement alone. The glasses in the video say “Prototype design,” and that is not the look of the shipping product.
How it differs from existing smart glasses
Everyday glasses with a camera lean toward shooting, translating, and showing things to an AI. Subvocal is closer to input only. The official page also writes that it is for people who want a keyboard substitute on a train or in an office where they cannot speak. It expects people who already use voice input every day, such as Wispr Flow, as the first customers.
The official FAQ also covers privacy. The explanation is that it does not read your thoughts on its own. It turns movement into text only when you move your mouth on purpose. It also writes that it does not depend on the noise around you. That is a claim, and there is no hands-on check yet.
Price and availability
On the preorder site, what you pay today is a $199 deposit, fully refundable until the final payment. The early price is $499, which is $200 off a listed $699. The remaining $300 is paid later. Prescription lenses are extra. Shipping is expected in Q1 2027. The page says FCC authorization is a condition.
Paid preorders are for the United States only, for now. A way to buy from Japan is not in this announcement.
What can be said for now
Glasses that sell input only, with no camera, are rare. Accuracy and finish are still ahead, and the official page also writes that the prototype and the shipping product look different. You still cannot buy them in Japan. For now, keep the primary figures on price and how it works.
