We Don't Change Behavior.
We Change Perception.
Being neurodivergent isn't a problem to be fixed — it's a reality that deserves better support. PsyAiHance builds adaptive, on-device AI that recalibrates your sensory feedback in real time — grounded in hard science. Our first product, FluxBuds®, is built for people who stutter..
Assistive Real-Time Sensory Neuromodulation. Designed To Wear.
One idea sits at the centre of everything we build: change perception, and you expand what people can do.
PsyAIHance builds AI-driven sensory devices that transform perception as it happens. Reshaping sensory feedback in real time unlocks new actions, capabilities and experiences — support that works in the moment itself, in your ear. Not only in the session afterwards.
We start with people who stutter. FluxBuds® is our first product.
Underneath: on-device machine learning and adaptive signal processing, grounded in decades of research into auditory-motor feedback loops, haptic processing and neural adaptation. Patent-pending algorithms, production-grade audio pipelines, and ecologically valid study designs — tested in real-world conditions, not only in the lab.
FluxBuds® — Fluency, Worn In The Ear.
Real-time speech support that works with your earbuds.
You know how stuttering often disappears when you sing, whisper, or speak in unison with someone else? FluxBuds recreates that effect — continuously, in your ear, while you speak. AI transforms your voice in real time so your brain hears it as someone else talking. That’s enough to quiet the feedback loop that causes blocks and repetitions. Your speech flows more freely, in the moments that matter most.
- Real-time, on-device machine learning — no cloud, low latency
- Non-invasive and wearable — looks like ordinary earbuds
- Discreet by design — support no one else can see
From research to real-world impact.
Our team combines deep perception science, production-grade audio engineering, and clinical rigor — built over decades across academia, industry, and the arts.
Perception Science as the Foundation
We don’t start with technology — we start with published mechanisms. 300+ peer-reviewed publications across sensory adaptation, auditory-motor feedback, and neural processing inform every product we build.
Production- Grade Real-Time ML
Real-time DSP and ML pipelines built at the world’s most demanding audio companies — including Ableton. Production-stable, on-device, sub-50ms latency.
From Lab to Life
We engineer for the moments that matter: phone calls, meetings, the classroom — not controlled environments. Published work in the German DiGA framework validates our real-world approach.
Designed With, Not For
Affected individuals shape our technology from the earliest prototype — as co-designers, not test subjects. Every iteration is driven by real feedback in real environments.
From decades of research in perception science and real-time signal processing — now translated into adaptive technology for real-world impact

” By respecting the seriousness of the condition and the need for careful evaluation. We can be optimistic and still be precise about what we know and what we’re validating. The research and development effort is structured around defined milestones, controlled evaluations, and real-world usability—not just demos.”

One Mechanism. Many Conditions. Multiple Solutions
Many neurodivergent conditions share a common root: disrupted sensory feedback loops that distort how the brain processes perception in real time. PsyAIHance® targets this shared mechanism through Real-Time Perceptual Neuromodulation — delivered through neuroadaptive wearables, personalized to each user.
Audio & Speech
Speak fluently, in real time
Disrupted auditory-motor feedback distorts how the brain processes its own voice — a core driver of stuttering. We restore fluent speech processing at the source.
FluxBuds® · LiveAttention & Cognition
Steady focus, less noise
Sensory overload destabilises focus and cognitive regulation — a central challenge in ADHD. Adaptive sensory environments reduce neural noise in real time.

Vision & Perception
Realign self-perception
Distorted perceptual feedback is believed to contribute to conditions such as body-image distortion. We're researching whether guided visual recalibration can help realign self-perception.
