Most fiction writers juggle Scrivener, World Anvil, Grammarly, ChatGPT, Plottr, and more just to finish one book. Ishvana is one desktop app that does all of it. Manuscript editor, worldbuilding database, plot studio, map builder, language workbench, mechanics engine, and print-ready book compiler. Local-first. $199 one-time. No subscriptions, no cloud lock-in. Bring your own AI or skip it entirely. Built by a worldbuilder who got tired of fighting his tools.
