CLUSTER SIDE-IMAGES-TWO · 20 ENTRIES · EARLIEST ENTRY 2022-08-21
Visual image comparison tools
This cluster consists of web, desktop, and mobile tools for comparing images visually, using side-by-side views, overlays, sliders, and automated difference detection, sometimes with natural-language explanations. Pre-index dated entries are sparse: one in 2022, three in 2025 (May, June, August), and one in 2026, too thin to reveal a clear trajectory. Traction leaders, all with zero stars, include SpotTheDifference, AI-Based-Duplicate-Image-Detection, and Image Compare.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
