Sign. Speak. Connect.
Nothing lost in translation.
Translating motion. Understanding meaning.
Natural communication, understood in real time.
Impossible, until now.
It was never a translation problem. It was a convergence problem.
Human communication doesn't travel through words alone. It moves through thousands of simultaneous signals.

Existing systems reduce sign language to a dictionary. We model the motion that creates meaning.
Doing that in real time required six fields to mature independently — computer vision, deep 3D landmark tracking, machine learning, large-scale translation, real-time multilingual speech, and GPU inference fast enough to run live over end-to-end encrypted streams. Each existed on its own. Only now can they run together, as one engine.
Six technologies. One engine.
The engine
One engine, built in layers.
Not six products bolted together. One integrated intelligence architecture, engineered as interdependent layers that only work as a whole.
- 01
Vision
Deep 3D capture reads the hands, body, and face in three dimensions — no gloves, no sensors.
- 02
Motion
Skeletal and gesture modeling tracks the true movement that carries meaning, frame by frame.
- 03
Expression
Micro- and macro-expression are read as language, not noise.
- 04
Language
Context and intent resolve into real meaning, then translate across languages.
- 05
Voice
Natural, real-time multilingual speech renders the reply aloud.
- 06
Inference
GPU inference is engineered to deliver the exchange live, over end-to-end encrypted streams.
Six layers. One unified intelligence.

Request clinical briefingThis is normal. It should not be.
The gap between Deaf and hearing people isn't abstract. It shows up in the moments that matter most, and today it's handled by scheduling, waiting, or simply going without.
A Deaf patient arrives at the ER. There's no interpreter on site, so one is dialed in on a cart, if a line is free. Otherwise the exam proceeds through hurried notes and a worried family member, in one of the most private moments of a person's life.
A daughter wants to tell her father about her day. A customer wants to open an account. A student wants to ask a question. Each is a small, human connection, and each one waits on a scheduled interpreter who isn't there.
This isn't about “fixing” anyone. Deaf and hard-of-hearing people navigate a hearing world every day. bitsign exists to restore autonomy and privacy, to make the connection instant and the third stranger optional. Under the ADA and Section 1557, effective communication is already required, yet fewer than 14,000 certified interpreters serve 48 million Americans with hearing loss.
A complete two-way conversation, in real time
bitsign runs both directions at once, so a Deaf and a hearing person can hold a natural conversation through a single device — on demand, without scheduling.
The camera reads signs and speaks them aloud
- 1.CaptureThe camera films the Deaf user signing, with no wearables, gloves, or sensors.
- 2.RecognizeHand and body keypoints are extracted frame-by-frame and decoded into language.
- 3.TranslatePredictive translation begins before the sentence finishes, designed to scale to 300+ languages.
- 4.SpeakNatural synthesized speech plays aloud for the hearing person to hear.
"Thank you."
Spoken replies become captions and a signing avatar
- 1.ListenThe hearing person simply talks; their speech is captured and transcribed.
- 2.TranslateWords are translated back into the Deaf user's own sign language.
- 3.CaptionLive captions appear on screen as the conversation unfolds.
- 4.SignA signing avatar renders the reply visually, completing the loop.
"Let's get your blood pressure checked, then I'll order a scan."
Six orchestrated layers, from capture to speech
bitsign is an integrated AI architecture built by a team spanning computer vision, real-time translation, and speech. The core multimodal system — vision, audio, and the orchestration that ties them together — is operational. Current development is concentrated on advancing the sign-language intelligence layer that completes the loop.
Vision capture
The camera reads hands, face, and body in real time, no gloves, wearables, or sensors. Just a phone or tablet.
Gesture recognition
Skeletal keypoints are extracted frame-by-frame and decoded into language. This layer is undergoing continuous performance optimization and validation.
Predictive translation
Translation begins before a sentence finishes, engineered to scale across hundreds of sign and spoken languages.
Natural voice
Synthesized, natural-sounding speech plays aloud for the hearing person, and captures their reply.
Signing avatar
Spoken replies render back into the Deaf user's sign language through an on-screen signing avatar.
Continuous learning
With consent, the system is built to keep improving over time, rather than training on fixed, quarterly datasets.
Underneath it all is a polylingual engine that turns human motion into meaning. Sign language is where we start; universal human motion to meaning is where we are headed.

For healthcare & enterprise
Lead on access before it's mandated
Whether you run a hospital, a dealership, a bank, or a law firm, the obligation to communicate with Deaf and hard-of-hearing people is already yours. Request a pilot or submit a letter of intent to shape workflow integration while founding terms are open.
- A private briefing on the bitsign pipeline and how it deploys in your environment
- A clear ADA and Section 504 accommodation overview for your obligations
- A cost comparison against your current interpreter or VRI contracts
- Founding-partner terms and priority pilot access before general availability
A limited founding cohort, onboarded in waves
To protect deployment quality, we onboard early users and pilot sites in deliberate waves rather than all at once. Founding partners get more than early access — they contribute directly to workflow design and deployment requirements.
Shape the deployment
Founding partners contribute directly to workflow design and deployment requirements within their own environments.
Establish founding terms
Early partners establish founding-partner terms, set before general availability opens.
Lead on access
Move first on accessibility, ahead of tightening enforcement, and be recognized as an organization that decided access couldn't wait.
We'd rather onboard a smaller group well than a large one poorly. When a wave is full, the next opens. No countdowns, no invented scarcity, just a real limit on how many partners we can serve at founding quality at once.
Equitable care for Deaf and hard-of-hearing patients
Healthcare is a legal effective-communication obligation, not a voluntary market. 6,000+ US hospitals and 900,000+ physician offices carry it today. bitsign installs on the devices you already own, is available on demand without scheduling, and is designed to expand communication access while reducing structural delivery cost. We start here, then expand to education and everyday life.
Primary & specialty care
Two-way translation in the exam room for intake, appointments, and follow-ups, instantly.
Urgent & emergency
Nothing to schedule. Point the device and the conversation starts the moment it's needed.
Pharmacy & front desk
Handle check-ins, consent, and medication counseling without leaving patients guessing.
Hospitals & health systems
Standardize communication access across every department and location on one platform.
The moment is now.
The demand is here, the mandate is enforced, and the access gap is measurable. The numbers make the case.
