Pendraic vs Substack

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.

Substack is a publishing platform for writers, creators, and subscribers, bringing posts, newsletters, podcasts, video, live streams, and pages into one publishing flow. Its editor supports scheduling, autosaved drafts, version history, templates, SEO metadata, and headline A/B testing. Creators can offer free or paid posts, subscriptions, trials, gifts, and group plans. Discovery tools include recommendations, Notes, leaderboards, referrals, and search; audience segmentation and email automation are also available. Podcast episodes can be distributed automatically to Apple Podcasts and Spotify, while video can go automatically to YouTube and LinkedIn. Publishing is free. When creators enable paid subscriptions, Substack keeps 10% of subscription revenue, and Stripe charges payment processing fees. Creators own their intellectual property and mailing list and can export their data. Substack serves writers, journalists, podcasters, video creators, experts, educators, and media companies. It is available on the web, Android, and iOS. Substack directs users to its Help Center and handles subscriber support questions on behalf of writers.
