The UK’s first AI-native platform converting live BSL gestures into spoken English and text in under 200ms — no interpreters, no hardware booths, no delays. Built for NHS Trusts, councils, schools and enterprises under the BSL Act 2022.
GestureFlow is the UK’s first AI-native British Sign Language translation platform. We use a hybrid architecture of CNN, RNN, LSTM and Transformer networks combined with GAN-based synthetic data generation to convert live BSL gestures into spoken English and real-time captions in under 200ms.
Born from a recognised accessibility crisis, our platform directly addresses the communication gap that affects over 12 million deaf and hard-of-hearing people in the UK. With human interpreters costing £43.50–£60 per hour and availability scarce, GestureFlow delivers always-on, 90% more affordable accessibility at scale.
Our TRL 7 prototype is operational and has already secured 8 Letters of Intent for pilot deployment across NHS Trusts, social care, industrial, and retail environments — with clinical validation underway at Royal London Hospital.

Validated with Royal London Hospital. Enables Deaf patients to communicate with NHS staff without interpreters — critical in A&E, GP surgeries and outpatient clinics. Fully NHS DTAC and GDPR compliant.
Provides real-time BSL accessibility in classrooms, lecture halls and online learning environments. Enables Deaf students to participate fully in mainstream education without requiring a dedicated interpreter for every session.
Supports local councils, courts and government service counters in meeting their legal accessibility obligations. Replaces costly VRI (Video Remote Interpreting) services with always-available AI translation.
Piloting with Morrisons Daily and Broadway News Agents. Embeds into self-service kiosks, customer service counters and contact centre platforms. Includes stress-testing for high-volume, fast-paced interaction environments.
From individuals exploring BSL technology to large NHS Trusts requiring enterprise-grade deployment — there’s a GestureFlow plan for you.
Perfect for individuals exploring real-time BSL translation. Start free, upgrade when you need more.
For developers, startups and organisations integrating BSL translation into their own applications and platforms.
Full-scale deployment for NHS Trusts, councils and large organisations. Dedicated SLAs, custom integrations and onsite onboarding.
Every competitor either serves ASL markets, requires specialist hardware, relies on pre-recorded video translations, or lacks real-time capability. GestureFlow is the only UK-built, software-first, real-time BSL platform — running on a standard webcam with no additional equipment.
CNN + Transformer fusion (DenseNet & Xception) with 3D skeletal tracking for micro-movement recognition.
Modular API integrates with NHS systems, LMS platforms, kiosks and public-service portals out of the box.
GDPR, NHS DTAC, BSL Act 2022, Equality Act 2010, ISO/IEC 27001 & WCAG 2.1 AA — all covered.
GAN-based synthetic data generation keeps the model evolving with new vocabulary, dialects and signing styles.
Six core capabilities that make GestureFlow the most complete BSL accessibility platform in the UK.
Sub-200ms BSL-to-English conversion using CNN + LSTM + Transformer networks. Processes 3D hand movements, facial expressions and body posture simultaneously for context-aware output.
Generative Adversarial Networks create synthetic BSL datasets that mirror real-world signing variations — regional dialects, signing speeds and emotional expression — without requiring user data.
Runs locally on standard webcams and devices with no internet required. 95%+ functionality retained offline — essential for rural hospitals, emergency rooms and community centres.
Built to satisfy NHS DTAC, GDPR, BSL Act 2022, Equality Act 2010, ISO/IEC 27001 and WCAG 2.1 AA. Includes DPIA, clinical safety case (DCB0129) and penetration testing documentation.
Open REST API and SDK packages plug into NHS PAS systems, telehealth platforms, education LMS, contact centres, kiosks and public-service websites — no custom hardware required.
All gesture data is processed locally or encrypted in transit and at rest. Federated learning model means user videos never leave the device. Full GDPR and UK data protection compliance.

Real-world validation across healthcare, retail, social care and industrial environments — before commercial launch.
GestureFlow has transformed how we communicate with our Deaf service users. The real-time translation is remarkably accurate and has made our front-desk services genuinely accessible for the first time. Our staff feel confident, and our users feel heard — without a single interpreter booking required.
Thought leadership on BSL accessibility, AI innovation and inclusive design for the UK’s public and private sectors.
The British Sign Language Act 2022 placed a legal duty on UK government bodies to promote and facilitate the use of BSL. We break down what this means for NHS Trusts, councils and public service providers — and how AI-powered translation is the most scalable path to compliance.
Read Article →Many organisations use static BSL video libraries to meet accessibility requirements. But deaf users need live, dynamic communication — not pre-scripted scripts. We explain why sub-200ms real-time AI translation is the only genuine solution for frontline accessibility.
Read Article →Over 151,000 people in the UK use BSL as their primary language. In emergency settings, the absence of a qualified interpreter can be life-threatening. Our clinical validation work at Royal London Hospital demonstrates how GestureFlow bridges this critical gap safely and compliantly.
