Granth: Where Your Book Lives

Granth is a local-first Writer Operating System for serious fiction and nonfiction. Your manuscript, research, characters, claims, and timeline live in plain Markdown and YAML folders you own outright, readable with or without the app. Bring your own AI key: a Project Brain that has read your whole book answers with citations, six editorial agents critique it, and publishing-grade EPUB, DOCX, and print PDF come out the other end. Nothing leaves your machine without your say-so.

Your files Plain Markdown and YAML in folders you could still open in fifty years. The database is only ever a rebuildable cache.

Your AI Any provider, your key, your rules. Cited answers from a Brain that has read every chapter, and nothing becomes canon until you accept it.

Your press EPUB 3, DOCX, and print-ready PDF, with KDP and IngramSpark preflight checklists built in.
