Subvocal's AI glasses let you type 200 wpm silently
Subvocal just raised $1.3M in pre-seed funding to build smart glasses that turn silent mouth movements into text. Using low-power radar-like radio frequency sensors and AI rather than cameras or microphones, the device tracks facial muscle shifts at over 200 words per minute. Pre-orders start at $499, targeting a 2027 rollout.
