Why we built this
We started TaleVein after working with AI writing tools that could generate text but were not designed for the full demands of long-form fiction. As a project grew, characters, timelines, story branches, and generated media quickly became disconnected.
That experience shaped TaleVein: a unified workspace where writers can develop manuscripts, generate and organise story media, build their world, and manage versions in one place. AI accelerates creation when useful, while writers retain control of voice, continuity, and direction.
Built by writers for writers who take long-form fiction seriously.


Start free, test the editor, and keep drafts, world notes, and branches in one workspace.
