FicWeave is an AI fanfiction generator built for multi-chapter stories rather than one-off chats. Start with a fandom or original universe, characters, relationship, trope and story idea, then generate and read Chapter 1 with no account required. When you save the story, FicWeave builds a visible Story Memory of characters, relationships, important facts and open threads, which later continuations draw on so the story stays coherent across chapters.
Saved stories live in a private library with chapter navigation, and you can review what the AI remembers — with source chapters shown — before continuing. Free accounts include 3 one-time starter credits that never expire and read-only Memory, while paid plans add monthly credits, more editable stories and Memory editing; Pro starts at $7.99 a month. A standard saved continuation uses 1 credit, and stories remain readable when credits run out.
FicWeave supports general fiction, romance, dark themes and non-explicit mature themes, but not explicit sexual content or sexualization of minors or identifiable real people. It suits fanfiction writers who want a long story that remembers its own cast and promises.
