5 out of 5 starsIbuku is everything I needed in an authoring tool. The dual-view author comments make editing drafts effortless, and the multi-strand timeline tracker keeps my narrative tight across multiple plot lines. Exporting clean Shunn ma***cripts and EPUB 3 books with zero hassle makes this an essential part of my writing toolkit. 10/10!
