One night of sleep record takes anywhere between 1.5 to 2.5 hours to score by an expert technologist. What if you could get hundreds of such records scored at expert level accuracy and higher reliability in seconds. In this world of ever increasing data - time and speed is everything!

At Your Service

Accurate and Reliable

We just released a new version of our scorer (called NEO) which was built ground up from scratch using 30,000+ hours of PSG data collected from 4000+ subjects. Our new system beats our previously published (Patanaik et al., 2018, Sleep doi:10.1093/sleep/zsy041) results by 30 to 40% lower error rates.

Real-time Scoring

Z3Score allows cutting-edge experiments that rely on real-time sleep stage information, like targetted memory reactivation, closed loop acoustic stimulation and lucid dreaming accessible to more researchers.

Open API

We offer our service as a cloud based Open RESTful API, so we integrate into your existing software and workflow. There are no steep learning curves, take a look at the demo.

Rapid Quality Checks.

Each sleep scored epoch also has an associated confidence. A score between 0 and 10, you can set your confidence threshold to get your desired level of quality. Figure below shows the percentage of data that is marked for review (bottom x-axis) for a corresponding confidence threshold value (top x-axis) and the automatic vs expert inter-rater reliability value for data that will not be reviewed (y-axis) for a representative dataset (more details will be published soon).

Get Started Now

Our cloud architecture makes it exceptionally simple to score small or large PSG datasets with ease. We support your favourite PSG software, so that you can continue using your existing workflow. Watch this 10 min getting started guide to see it in action:

Go ahead and start scoring your PSG data using our neo commandline tools for Windows. Or if you are a developer you can read our API documentation here.
