Every platform plays hashtags differently: Instagram rewards niche-mix strategies, YouTube wants a focused handful, Facebook prefers a light touch. Using one generic hashtag list everywhere quietly kills your reach on all three.

UploadFlow AI generates per-platform hashtag sets from a single topic prompt — each set sized, mixed and ordered for how that platform's algorithm actually treats hashtags.
