From your data to a figure

• Bring your own data. Load your Fixations, Words or Raw gaze tables, and add participant, trial and text metadata. Data guide →
• Explore and replay. View fixations, saccades and heatmaps, and replay a reading fixation by fixation. Filter trials, then star or tag the ones to revisit.
• Compare readings. Overlay two scanpaths or place them side by side, from two participants, conditions or datasets.
• Analyze a corpus. Summarize the reading measures in your data by text, participant or group.
• Export and share. Save publication-ready figures, GIF or MP4 replays, or a batch of trials. Share a view as a link.
