Readless is an AI digest service that summarizes newsletters, Substack publications, and RSS feeds and delivers the results on a schedule. It works with received newsletter text and content available through connected feeds, so readers get one digest instead of many separate emails.
The product began in mid-2025 as a one-person project. Its creator, based in California, built it after reading the same news told several ways each morning. Readless is bootstrapped, says it runs no ads and does not sell data, and links every summary back to the original so readers can verify important details.
Setup starts with claiming a personal address on the @mail.readless.app domain. Users forward newsletters they already receive or use the address to subscribe to new ones. Substack can be connected by handle or publication URL, and accessible RSS feeds can be added to any schedule.
Next, the user picks weekdays, a delivery time, a summary style, and a digest language for each schedule. Readless generates summaries of the supported content in that schedule and sends the digest. Source references let readers check facts the summary may have left out.
Pro offers Concise and Detailed source summaries, with each source summarized separately. Hot Topics adds a layer on top by highlighting a specific story covered by at least two distinct senders. Summary instructions aim to omit promotions and boilerplate, and insights are organized by topic.
Max adds a Synthesis editorial briefing, a thematic narrative with source references, plus custom summary instructions that steer tone and focus. Both plans support per-schedule language selection, with 12 languages listed, and sender filters for each digest. Stored newsletters can also be read in the dashboard.
