Pick Chiasm if…
Chiasm suits researchers and organisations running remote webcam-based studies, particularly those using Qualtrics, jsPsych, or custom web studies. It is not intended for personal consumer use.
Pick iTrace if…
iTrace may suit science and research users exploring eye-movement estimation methods with webcam capture or gaze CSV data. It is best treated as a reference implementation, with comparison to a reference device or public dataset before making device-level accuracy claims.
