For people who can't speak, the existing tools type words and play them back. We're building something different: a system that learns how you want to communicate — your rhythm, your humour, the things you actually mean to say — and gets closer to it every conversation.
Augmentative and Alternative Communication (AAC) has spent thirty years optimising for one thing: throughput. Get the words out faster. We think that's the wrong target.
The other person speaks. Their words are transcribed live. A language model trained on your voice generates a handful of responses you might actually say. You pick one. It's spoken aloud. All in under a second.
The microphone captures the other person speaking. Streaming speech-to-text turns it into live text with sub-300ms latency.
While they're still talking, the model is already drafting replies — four options, varied in length and tone, written in your voice.
You tap the one closest to what you want to say. Or edit it. Or save the whole set as a snapshot and come back to it.
High-quality voice synthesis speaks the reply aloud. Every interaction is logged — quietly, privately — so the model gets to know you better.
The same intelligence powers both. Choose the form factor that fits your life.
For people who already have a device. Sign in, set your voice, start talking. Designed to run on an iPad mounted to a wheelchair, a tablet on a desk, or any modern browser.
For people who want a purpose-built tool. Bone-simple hardware, touchscreen, dedicated microphone. Designed to work offline as the underlying models mature. Lives on the table, ready to go.
Every conversation through Ariel is, with consent, a data point. Over months and years, the system learns the things only you would say: the references, the rhythms, the in-jokes, the people you care about, the topics that come back week after week.
That's not voice cloning. That's voice discovery — finding and amplifying the way you already think, so that what comes out of the device sounds more like you over time, not less.
The endpoint isn't an assistant that speaks for you. It's a second mind that knows you well enough to speak with you. We think this is the most important thing assistive technology can be doing in the next decade. We're building it now.
We're letting a small number of people in over the coming months. People who use AAC, families, clinicians, researchers. Tell us who you are and we'll be in touch.
