Substack

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.
