Extypis is a writing studio for authors working on stories too large for one document. Write your manuscript, organise scenes on a storyboard, connect characters, places and objects, keep research and notes nearby, and share one world across a whole series. Mentions in the text lead back to their profiles. Context-aware AI can continue or rewrite a selected passage when invited, and disappears completely when disabled. Export polished PDF, DOCX, EPUB, Final Draft and more.
