CLUSTER PLAYLISTS-YOUTUBE-CERTIFICATES · 11 ENTRIES · EARLIEST ENTRY 2026-04-07

YouTube playlist course converters

This cluster consists of apps that transform YouTube playlists into structured courses with features like quizzes, progress tracking, and certificates. The dated history is too thin to read a shape from, as only four dated entries exist before the index start. Among traction leaders, Tubelearn leads with 1 star, while cutlist and pathways-3d-learning 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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 11 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
