Screenshot annotation tools

This cluster consists of desktop and web tools that capture screenshots and annotate them with arrows, shapes, text, and blur. Dated entries are sparse: a single entry in 2014, 2021, 2024, and 2025, then 1 in April 2026, 2 in May, and 4 in July 2026. LensIt leads on traction with 4 stars, while other dated members have 0 stars.

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.
