Readbase is a newsletter reading app for iPhone and the web. It gives you a dedicated inbox just for newsletters at your own @readbase.io address, keeps them out of your email, and puts an AI summary on every newsletter so you can tell in seconds what is worth reading.
All of them. Readbase works with newsletters from Substack, Beehiiv, Medium, ConvertKit, and any other provider that sends emails.
We create a private inbox for you at @readbase.io. You subscribe to newsletters using that address, and they appear automatically inside the app - separate from your email.
Yes, with Readbase Premium. While you read, Ask AI summarises the key points, explains any passage, adds background on the topics and relates the ideas to your own situation. Select any text and tap Explain or Ask AI. Answers are grounded in that newsletter and say when they add context beyond it, and your chats are not stored.
Yes, on iPhone. Say "Summarize my latest Stratechery in Readbase" and Siri reads you the AI summary, or "Mark everything from TLDR as read in Readbase" to clear a subscription without opening the app. The same actions are in the Shortcuts app, so you can add them to your own automations, and your newsletters and subscriptions show up in Spotlight.
Readbase is available on the App Store for iPhone (iOS 18.0 or later), and on the web - read your newsletters from any browser. Download on the App Store, Open the web app
Yes. Privacy is a core principle of Readbase. We don't read your personal email, we don't sell your data, and your newsletters are only used to provide features like offline reading and summaries.
