In this interview, we sit down with Founder Luke Kist to discuss Tinky Town, a QR-code-based auxiliary communication infrastructure. By acting as public accessibility infrastructure, the platform aims to bridge the gap between non-verbal or non-English speaking visitors and front-desk staff in facilities worldwide.
Tinky Town is a QR-code-based auxiliary communication infrastructure designed to bridge the gap between non-verbal or non-English speaking visitors and front-desk staff in public and private facilities. Rather than serving as a personal, dedicated AAC (Augmentative and Alternative Communication) device, Tinky Town acts as public accessibility infrastructure—similar to a wheelchair ramp or Braille signage. Now’s a good time for Tinky Town to exist because recent advancements in lightweight, on-device AI make it possible to instantly provide secure, privacy-focused communication tools without requiring users to download an app or purchase dedicated hardware.

Primary Users (Visitors): Non-verbal individuals, AAC users, neurodivergent visitors, people with speech impediments, and non-English speakers who need to communicate quickly at front desks without specialized personal hardware.
Secondary Users (Venues & Staff): Front-desk personnel, receptionists, and customer service staff at public and private facilities (e.g., libraries, community centers, municipal offices, museums, healthcare clinics, and retail establishments).
Value Provided: Visitors get immediate, barrier-free communication without app downloads or specialized setup. Venues gain a low-friction accessibility solution that enhances inclusivity, customer service efficiency, and compliance with accessibility standards.
Tinky Town relies on a custom, lightweight AI stack built entirely from scratch, utilizing proprietary models like the 31-million parameter TinkyBrain-31M and the on-device PEEL-conditioned TinkyBrain-v6 hosted on the Hugging Face Hub. We prioritized building our infrastructure to run locally on constrained hardware because it ensures data privacy, ultra-fast response times, and supreme reliability for vulnerable users without depending on massive cloud architectures.
While Tinky Town is currently in a stealth, pre-launch phase to build out its infrastructure, our standalone AAC communication device, TinkySpeak, has already gained strong early validation. TinkySpeak has been featured multiple times by autism advocacy communities and therapeutic centers, proving that there is a genuine organic interest and trust in our underlying tech stack before the broader public rollout of Tinky Town.
Democratizing Accessibility: Brings zero-cost, immediate communication tools to non-verbal individuals, non-English speakers, and stroke survivors who are often overlooked in public spaces.
• Restoring Independence: Gives visitors a simple way to speak up for themselves in real-world scenarios—like municipal offices, clinics, and local stores—without relying on an interpreter or personal AAC device.
• Low-Barrier Deployment: By framing accessibility as venue infrastructure (via simple QR codes), facilities can achieve meaningful inclusion instantly using light, on-device AI.

The most compelling evidence of need comes from our sister project, TinkySpeak: organic adoption and recurring daily usage by speech language pathologists (SLPs) and non-verbal users within autism communities and therapeutic centers without paid acquisition. Users actively rely on our custom TinkyBrain architecture for immediate, daily communication—proving that light, low-latency AAC tools fill a vital real-world gap where traditional software is too complex or costly.
Because Tinky Town operates as frictionless public infrastructure without requiring sign-ups or app downloads, we measure adoption through repeat interaction depth per venue QR code rather than account registrations:
Audience Reach & Impact will show the single biggest jump.
We discovered HackerNoon through its developer community discussions surrounding open-source AI and small language models. Participating in the Proof of Usefulness hackathon has been fantastic—the platform's emphasis on real utility and technical substance over vanity metrics directly aligns with our mission to build lightweight, privacy-focused accessibility infrastructure.
Therapeutic centers, advocacy groups, and families using TinkySpeak already experience the benefits of our underlying TinkyBrain models. We are leveraging these established relationships in two ways:
Our onboarding strategy focuses on minimizing friction for front-desk staff:
To ensure high accuracy across vastly different environments (e.g., municipal offices vs. healthcare clinics):
