Mission

Real-time sign language translation should be free, accurate, and shaped by the people who use it. SignBridge exists to make that possible — on a phone you already own, with no subscription, no recording, no surveillance.

We believe accessibility tools work best when they’re owned by the community they serve. So the model improves as more deaf and hearing signers contribute, every contribution is anonymous by default, and the data never leaves the system as video.

Why we’re building this

Existing translation services are either expensive, slow, dependent on human interpreters being available, or rely on cloud-based ML that captures and stores video. None of those work in a doctor’s office at 2am, or in a coffee shop with spotty WiFi, or in a classroom where you don’t want a recording sitting on someone else’s server.

The hardware to do this on a phone exists. The on-device ML to do this respectfully exists. What was missing was the software, and a community willing to make it open. So we’re building both.

Who’s behind it

SignBridge is a Skyline Vis project. Skyline Vis is a small studio focused on accessibility-first applied ML. We’re a small team and a growing community of contributors — deaf and hearing, signers and learners, who agree that this should exist.

How it’s funded

Self-funded for now. Free during beta, and free forever for anyone who has contributed signs. We’ll figure out sustainable funding once the product is good enough to charge for — likely a freemium model where contributors keep free access for life and casual users pay for advanced features. We won’t take VC money in a way that compromises the privacy commitments above.
