Calliope is a web-based tool for planning and drafting books. Writers can outline a book, work in a chapter workspace, and use continuity tools to keep manuscript details aligned. Finished work can be exported as Markdown, Google Docs, DOCX, EPUB, or PDF. The Free editor plan allows unlimited books. For AI allowance, Calliope lists one-time credit packs and subscriptions: a €10 pack adds a €10 balance, a €50 pack adds €55, and a €100 pack adds €120. The monthly subscription costs €12 per month and includes a €10 monthly AI allowance that resets every 30 days. The annual subscription costs €99 per year and also includes a €10 monthly AI allowance. The listed plan details describe book capacity, balances, and allowances; they do not specify other editor functions. Calliope is made by a company headquartered in Bratislava, Slovakia.
