Private, on-device AI for the people technology forgot.
EchoSense is a navigation wearable for the visually impaired and a calming companion app for autistic users — both powered by AI that runs on the device, not the cloud. Zero conversation bytes ever leave.

One mission, two devices
The technologies built for visually impaired and autistic users either cost more than a car, demand a cloud subscription, or were never designed for them. We took a different path.
“285 million people live with visual impairment. One in 100 children is autistic. We refused to accept that dignity should cost a subscription.”
Affordable by design
built from off-the-shelf parts to stay far cheaper than commercial smart aids and guide dogs.
Offline-first
full multimodal AI runs on the user's own phone and on the wearable's edge compute.
Safety is sacred
hazard detection is isolated code that never depends on the AI model or the network.
Consent-bounded
caregivers connect only with permission, and access is revoked instantly on removal.
Engineered around four convictions
Private by design
All conversational AI runs on the user's own device. The cloud backend only handles accounts, linking and caregiver sync — never the contents of a conversation.
Affordable on purpose
Built on commodity Raspberry Pi hardware and off-the-shelf parts — dramatically more affordable than commercial smart aids and trained guide dogs, and designed for emerging-market budgets.
Safety is unconditional
On the wearable, hazard detection is pure, isolated code that never imports the AI model. If everything else crashes, the user is still warned.
Benchmarked, never assumed
Every model and sensor is measured for latency, accuracy and power before it ships. 14 documented architecture decisions back every major choice.
