What Readless is
Readless is a web-based service that turns newsletters, Substack publications, and RSS feeds into scheduled AI summaries delivered by email. It detects overlapping stories across sources, merges them into one summary, and links back to contributing newsletters. Text-based newsletters are filtered for ads, tracking pixels, and promotional elements. Pro users can connect Substack by handle, profile URL, or publication URL, and add RSS feed URLs to schedules. Pro and Max support summaries in 12 listed languages, though original articles are not translated. Max adds Synthesis, which combines sources into a thematic editorial brief with citations. Readless works with email providers including Gmail, Outlook, Yahoo, ProtonMail, and custom domains. It is standalone and mobile-responsive; native mobile apps are under consideration. Primarily image-based or PDF newsletters are not summarized, but remain in the dashboard. Pro costs $4.90 a month and Max $9 a month, both billed monthly. A 7-day trial is listed, with no free plan.
