About us
A Structured Home for Manga Theories
Theorydeck is a platform for building, testing, and discussing manga theories through evidence.
Why Theorydeck exists
Most theory communities are built around posts, comments, and opinion. Theorydeck is different: it gives every claim a structure.
The core workflow
Readers can search source material, save scenes into a personal Workspace, turn those scenes into Evidence Chips, and use them to build or challenge Theory Cards.
From search to discussion
The core workflow is simple: search the manga, collect what matters, shape it into evidence, organize the argument through Narrative Lens, publish a Theory Card, and discuss it in context.
A living theory system
Theorydeck is a place where theories can grow stronger over time as new chapters, better evidence, and sharper counterarguments appear.
Launch focus
The first deck is focused on One Piece, but the system is designed around a broader idea: theories should be preserved, tested, compared, and updated as the story changes.
