Pendraic
What it is
Pendraic is a long-form fiction writing tool that keeps a book’s characters, world, voice and story details together. Its editor offers prose, outline and arcs views, with optional panels for character lookups, voice consistency, beats and unresolved threads. Planning and revision follow eight areas: Promise, Engine, Nexus, Dynamics, Registry, Anchors, Iterations and Closure. The World Builder links maps, family trees, calendars, languages, timelines and encyclopedia entries to prose. AI options include Claude, ChatGPT, Gemini, Grok and OpenRouter, accessed through a user’s own account or a Pendraic Managed AI wallet. When a user starts an AI generation pass, the prompt and needed context go to the selected provider under that provider’s terms. Pendraic says saved files are encrypted at rest and in transit, and that it does not train models on users’ writing or sell their content. The Free plan is free, supports up to three active books and includes Word, Markdown and plain-text exports. Paid plans start at $14.99 a month.
