Research stays on this scene. It is not a movie browser and there is no Discover page. WRITE • Split a notebook into scenes with INT/EXT and Day/Night • Keep characters in a list you can pin a face to • Focus mode for the page in front of you • Export as text, Fountain, or PDF — the manuscript, selected scenes, or this scene’s research PIN TO THIS SCENE • Place — stills and walking videos, or a location photo you took • Face — search an actor, or pick from a film’s credits • Voice — interviews, or a line you record yourself • Rhythm — trailers, for pace YOUR PAGES STAY HERE No HelloSix: SceneUp account.

Verdict
The clearest difference is ads: Sekai at none against HelloSix's shown. Sekai also leads on update cadence (every 3 days vs every 3 weeks) and ratings volume (31K vs 2). On price, rating, in-app purchases and device support there is nothing between them.
