About EEGSimLab

Critical care EEG on your phone. Every EEG is synthetic.

An educational simulator for learning critical care EEG patterns, one pattern at a time, with the ACNS 2021 terminology. Every EEG in it is synthetic, and it uses no patient data.

How it was built

EEGSimLab's code was written entirely with an AI coding assistant, Claude Code (Anthropic). The author directed the work and chose the clinical content, models and sources listed below. Every commit records the assistant as co-author, and the code is checked by an automated test suite.

The page uses no third-party libraries, fonts or icon sets: the icons are drawn for EEGSimLab, and text uses the device's system font.
