01 · the premise

Understanding is the new interface.

LLMs are trained to finish the task, not to work out what you want. xevall is a world model of human intent, predicting what you want a machine to do next, for better human-AI interaction.

02 · natural inputs

Interfaces are losing their keyboards.

What replaces typing is you: speech, tone, gaze, gesture. Intent comes from those signals and from connected context that learns over time: your calendar, your history, your preferences. A machine with both knows what you mean as you say it, and sometimes before.

03 · system misfires

Nobody measures the understanding.

When an AI system misunderstands a person, the product feels broken and the reason stays hidden. xevall grades the system against the meaning a human reviewer established, and hands back the moment it went wrong.

05 · the improvement loop

Every interaction creates traces to improve your product.

You already eval the words. Nobody is evaluating the coherence between the modalities: the tone, the distance, the body language. xevall grades whole interactions against human judgement, marks where the understanding broke, and re-scores the same sessions once you have fixed it. The grading exists to make products more human, not to mint a number.

the Human Input Benchmark

The Human Input Benchmark goes public this autumn.

Building a product around voice, timing, gaze or gesture? Early access is open for teams testing natural interfaces.
