About

Readbase is the inbox that's just for newsletters. Get your own private @readbase.io address, move your Substack and other subscriptions there, and every newsletter arrives with an AI summary. Get the point in seconds instead of reading every word, and save 4+ hours every month. Free to start. No credit card required. YOUR PRIVATE NEWSLETTER INBOX • Your own @readbase.io address, just for newsletters. • Subscribe once and keep newsletters completely out of Gmail, Outlook and your work email. • Moving from Substack takes one email change, and every subscription follows. • Substack's own notification emails stay out by default, so you only see the posts. AI SUMMARIES FOR EVERY NEWSLETTER • Every newsletter arrives with a summary crafted for long-form writing. Get the key ideas before you even open it. • Daily Recap: start each morning with one AI summary of your unread newsletters, so you know what's worth reading at a glance. • Ask AI: ask anything about a newsletter, or select a passage to have it explained. (Premium) Skim the summary, ask AI for the rest, and read in full only what is worth it. READ ANYWHERE • Offline Mode: everything stays available on flights and commutes. • iPhone and web: read in the app or at readbase.io, always in sync. • Siri & Shortcuts: ask Siri for your latest summary, or mark a subscription as read, hands-free. STAY IN CONTROL • 1-Click Unsubscribe: drop the newsletters you stopped reading in seconds. • Bookmarks: keep the newsletters you want to come back to. • Reading Stats: see what you actually read and build better reading habits. (Premium) WORKS WITH EVERY NEWSLETTER Read newsletters from Substack, Beehiiv, Ghost, Kit (ConvertKit), Medium, Buttondown, Mailchimp and any other provider that sends by email. One app for all your newsletter subscriptions, from daily briefings to long-form essays. PRIVACY-FIRST Your newsletters are yours. Readbase doesn't sell your data, and newsletter content is only used to power features like summaries and offline reading. FREE AND PREMIUM Readbase Free: your private @readbase.io inbox, AI summaries for every newsletter, Daily Recap, 1-click unsubscribe, bookmarks and offline reading. Readbase Premium adds Ask AI, the latest AI models for your summaries, Reading Stats with monthly insights, smart unsubscribe suggestions and push notifications for new newsletters. Billed monthly or annually. Cancel anytime. If newsletters are getting lost in your email, Readbase gives them a calm home of their own: just newsletters, summarised and ready to read.
