Enter one public channel and the tool scans thousands around it, ranking videos by how far each beat its own channel's average rather than by raw views.
Aggregates pain points, praise and requests across roughly twenty expert channels at once, with counts so recurring themes stand out.
Names every offer behind the channels in your niche — lead magnets, services, programs, communities — and identifies which brands sponsor them.
Generates titles, descriptions, tags and chapters benchmarked against videos that genuinely outperformed in your field, not generic best-practice templates.
