RealEye.io vs gptkit.ai

RealEye.io is an online research platform built around webcam eye tracking. You set up studies in a browser, send participants a link, and collect gaze data from their laptop or phone webcam without shipping hardware or installing lab software.

The platform covers the full research loop: study design with images, videos, or live websites as stimuli, remote data collection, and an analysis dashboard with heatmaps, fixation plots, AOI stats, facial coding, and CSV export. Researchers at agencies, brands, and universities use it for UX testing, shopper research, ad testing, and academic work.

RealEye runs gaze prediction in the participant's browser and stores coordinate data rather than webcam video, which keeps sessions GDPR compliant. A 7-day free trial is available with no credit card required.

GPTKit checks whether a passage was written by a human or generated by ChatGPT. Paste text or upload a file, and six detection models return a verdict plus an authenticity report for research, editorial, and hiring workflows.

Most detectors lean on one scoring method, which makes them easy to fool with light edits. GPTKit stacks six approaches and reports roughly 93% accuracy on a 100K-response test set trained on one million samples. That multi-model setup is the main reason to pick it over simpler checkers when a wrong call would actually matter.

Teachers, editors, freelancers, and hiring teams use it to screen essays, cover letters, and client drafts. Guest checks cover the first 2,048 characters with no account. Registered users get the same per-request limit on the free tier, and paid credit plans unlock longer scans through the Upgrade flow.
