Writing space

Manuscript center stage

  • Page or flat surfaceBook-like page or square canvas — your choice, remembered.
  • Agent that appliesInsert at cursor, recreate the document, or save replies as Artifacts.
  • EN · ES-419 · PT-BRUI and AI replies follow your locale; craft still respects manuscript language.

Story Bible

Characters, places, beats — scan and grow

Scan merges; it does not wipe. Outline, manuscript, characters, locations, and artifacts stay in one resizable column beside the page.

  • Character sheetsRole, archetype, motivation, conflict — open without leaving the draft.
  • Locations with sensesSight, sound, smell, and history next to the prose that uses them.
  • ArtifactsKeep agent answers as openable docs, not lost chat.
