CogS

Research tools that stay inspectable.

CogS is an open-source research-engineering initiative for browser-based cognitive measurement. The aim is not a sprawling platform. It is a small, readable stack for tasks, analysis, and public documentation that can be checked by other researchers.

PULSE

PULSE is the first active CogS project. It runs short, controlled browser tasks for reaction time, attention, and working memory. The current public release includes Arithmetic, Flanker, and SART. N-back is the next milestone in progress.

Public app: pulse-ezz.pages.dev

Why this exists

Research first

The emphasis is controlled task behavior, explicit data fields, and analysis that can be rerun. The public site is meant to describe what exists, not to overpromise what might exist later.

Conservative by design

No medical claims. No casual brain-training framing. No hidden tracking. The default public posture is local-first until a hosted research backend is ready and documented.

Open artifacts

Code

Source code is published under Apache-2.0. Protocols, diagrams, and written documentation are published separately under CC BY 4.0.

Documentation

The public documentation describes scope, data boundaries, and deployment posture in plain language so a cold reader can recover the real state of the project quickly.
