About RedThread
RedThread is a worldbuilding and story-planning app for iPad. It is made for fiction writers whose characters, places, histories, secrets, and scenes belong to one another—not to separate piles of notes.
What RedThread is
RedThread treats a story as a living narrative web. A character can belong to a family, carry an object, keep a secret, cross an event, and change a chapter. Those connections stay close, so returning to a large project feels like continuing—not reconstructing.
Built for the return
Open a story and find the cast, open threads, recent work, and the shape of the project waiting for you. RedThread is especially for writers returning after the story has gone quiet for a while.
Made for connection
Characters, places, families, groups, cultures, events, items, lore, and secrets can meet in the same story web. Relationships can carry their own meaning and status, because “knows” and “no longer trusts” are not the same fact.
Why it exists
Big fictional worlds create a second job: remembering where every fact lives and what it affects. RedThread exists to carry more of that weight, while keeping the writer—not a service, feed, or algorithm—at the center of the work.
For novelists, serial writers, worldbuilders, and anyone carrying a story too interconnected for a folder of isolated notes.
The short version
It does not write the story for you. It keeps its people, places, events, secrets, and consequences close enough that you can.
