Finding the drift without gel
Where our dry-electrode onset detection agrees with clinical PSG — and where it still misses.
Eidolon OnePrototype 001 — 2026
Your best thinking happens asleep
A dry-EEG headband that catches the moment you drift off — and plays back something worth waking up to.

The device
Introducing Eidolon One
A dry-EEG headband that notices the moment you fall asleep and plays a short audio cue built around a topic you chose. Four steps, every night.
Step 01
Onset detection
Finds the window while you drift
Dry-EEG sensors read the moment you slip from waking into early sleep — the narrow window where the mind is most open — without anything to set up or press.

Status — building the first prototype
We are building the first prototype, and the waitlist is open now.
Early units go to the waitlist first, in the order people joined. The list is small on purpose.
How it works
Neuroscience meets your nightstand
Dry electrodes read the slide from wake into early sleep — no gel, no clinic. On-device signal processing finds hypnagogia, the drifting state the protocol depends on, and nothing leaves the band unless you ask it to.
The method comes from published work, not a hunch. Setup is a few minutes, the guidance is written in plain language, and a real person answers when you write in. We would rather explain the science than hide it.
You pick a topic before bed and put the band on. As you drift, it plays a short cue built around that topic, then lets you fall the rest of the way. In the morning the session is waiting for you, not lost.
The idea
Your dreams don't have to be random
The mind at sleep onset is loose, associative, and unusually open. Eidolon points it at the one thing you chose to think about — then gets out of the way.
Why Eidolon
Why people choose Eidolon
Grounded in research
Built on MIT Media Lab's published Dormio and Targeted Dream Incubation work.
Dry EEG, no gel
A fabric band you can put on yourself in bed — no clinic, no mess, no wires.
A cue built per session
The audio is generated around the topic you chose that night, not one scripted line.
Your data stays yours
Sessions live on your device by default. Nothing is sold, and nothing leaves without you.
FAQ
Questions. Answered.
We don't know yet, and we won't pretend to. It is a prototype. Nothing is for sale, and joining the waitlist costs nothing and commits you to nothing. When there is a real price, waitlist members hear it first.
It might not. Sleep-onset cueing is an active area of research, effects vary between people, and some nights nothing lands. We would rather tell you that plainly now than oversell a prototype.
Sessions are stored on your device by default. We do not sell data, and nothing is shared or uploaded unless you explicitly choose to. If we ever offer cloud sync, it will be opt-in and clearly labelled.
A tracker measures your night and reports back in the morning. Eidolon acts during the night — it detects the moment you drift off and plays a short cue in that window. It is about the transition into sleep, not a score for it.
The cue is a quiet audio prompt timed to the drift into sleep, not a shock or a bright light. It is designed to work with the transition rather than interrupt it. There are no implants and nothing invasive — it is a fabric band.
No. The session is captured for you and waiting in the morning, so nothing depends on you waking up and scrambling to write it down before it fades.
We are building the first prototype now, so there is no ship date to promise. The honest answer is: join the waitlist and we will write to you the moment there is something real to try.
