Living Writing is a writing tool in which the writer only writes. Long stories go wrong in small ways: a dead character speaks, a town that burned is thriving, someone’s hair is long again. Today the only fix is re-reading earlier chapters. In Living Writing, an agent reads each scene the writer hands in and keeps a wiki of the story true: pages for people, places and things a short-lived “state” for each character a check that each new scene doesn’t contradict what the wiki already knows The wiki is versioned in story time. Stories are tracks on a timeline. Moving the playhead shows the world as it stood at that moment. Every page keeps its versions, and every line knows which scene wrote it. A flashback is checked against the story as it was, not as it is now. Everything the agent writes can be taken back in one click. A Flow reader shows where each scene sits in the whole story and how its tone shifts, without ever writing for the writer. It also has placeholder portraits, Ctrl+K navigation, light and dark themes, and plain Markdown export. It works offline in the browser; server mode adds accounts and the agent.
