In their own words
Chiasm
Chiasm captures gaze data through participants’ webcams for remote online studies and research. It processes webcam frames in real time and produces timestamped gaze coordinates linked to study events, together with session metadata. Researchers can connect it to Qualtrics, jsPsych, or custom web studies through a JavaScript library. Chiasm says studies can include hundreds of participants at once. Researchers can download gaze data from Chiasm or stream it to their own server; when used with platforms such as Qualtrics, data is held on Chiasm’s servers for later export. Webcam video is not stored by default, though limited calibration or validation recordings may be retained with explicit opt-in consent. The service supports Google Chrome on laptops and desktop computers with webcams. Flex has no monthly minimum and costs €0.25 per minute. Starter is €199 per month with 900 participant-minutes included, and Pro is €499 per month with 3,000 participant-minutes included. A 7-day trial is listed.
