An AI that reads the signal.

Noushen reads any complex system — your keystrokes, your biosignals (EEG, heart rate, HRV, blood oxygen, respiration), your voice, your agent telemetry, your patient vitals — and infers one real-time state from all of it together. The more signals you give it, the sharper the read.

In this chat it’s reading your typing rhythm. Connect a Muse headband, an Apple Watch, or any wearable you have and it reads those alongside — not instead. The substrate fuses every available signal into a single state estimate.

What you’ll see in this demo

A state pill in the top right that shifts as you type — in the zone, a lot on your mind, running low, bouncing back. Replies adjust with it: depth when you’re focused, clarity when you’re overloaded. EEG layered in sharpens the read; keystrokes alone, it does its best.

Want to plug your own signal in?

The same substrate is exposed as a developer API. Send observations from a Muse, an Apple Watch, a wearable, a voice stream, a clinical vitals feed, or any sensor — it ingests them together and returns one fused state vector. Email hello@noushen.ai for early access and integration steps.

About Noushen settling in
What does Noushen do?
Noushen reads how you’re engaging — your rhythm, your focus, your fatigue — and adapts its replies to meet you where you are. When you’re locked in, replies go deep. When you’re running low, they get shorter and clearer.
What does it actually read?
In this chat: your typing rhythm — speed, hesitation, corrections. Connect a Muse, an Apple Watch, or any other signal source and it reads those too — biosignals (EEG, heart rate, HRV, blood oxygen), voice, vitals, anything time-series. The substrate fuses every available stream into one state estimate. More signals = sharper read. What you type isn’t analyzed; only how you type.
What do the labels mean?
dialed in — focused & engaged
in the zone — deep flow state
locked in — intense focus
running low — getting tired
losing steam — extended effort showing
a lot on your mind — high cognitive load
coasting — low engagement
bouncing back — recovering
settling in — warming up
Is my data private?
Only the timing of your keystrokes is processed — rhythm, not the characters. Nothing is shared, sold, or used to train models. Email hello@noushen.ai to delete your data at any time.

Reads any signal.

Noushen infers state from any complex system — keystrokes, biosignals (EEG, heart rate, HRV, blood oxygen), voice, agent telemetry, vitals. Right now it’s reading your typing rhythm. Connect a Muse or an Apple Watch and it reads those too — the substrate fuses every available signal into one state estimate. More signals = sharper read.

works best with EEG layered in. doing its best with keystrokes alone.
Want documents, peripherals, and a system-wide read? The desktop app does all of that — coming soon.
