Pendraic vs Zettlr

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

Zettlr is a writing workbench for projects that can run from early notes through journal submissions and book manuscripts. It began as a Markdown editor for academic researchers and is also used by students, journalists, authors, and others writing substantial amounts. The app works offline on Windows, macOS, and Linux, and files stay on the user's computer. It supports standard Markdown and exports to formats supported by Pandoc. Citation manager support includes Zotero, JabRef, and Juris-M, with more than 9,000 citation styles. Note features include IDs, wiki-style internal links, related files, navigation, and graph view. Pandoc-powered profiles can apply templates to papers or prepare presentations for Beamer, reveal.js, or PowerPoint. Zettlr also renders LaTeX equations and Mermaid charts and supports extensive settings and custom CSS. It is free and open source, with no payment required to download. The maker says app data is not collected and update checks can be disabled. Older releases are unsupported; nightly releases may contain many bugs.
