Our verdict on Sloww
Sloww is a web-based lifelong-learning resource created by Kyle Kowalski for people exploring intentional living, life purpose, mental mastery, and related interdisciplinary topics. Its free offering includes detailed nonfiction book summaries, recommendations, a curated reading list, the Sloww Sunday newsletter, articles, and ebooks. Premium membership extends that library with members-only articles and infographics, the Sloww Society community, mobile app access, and a Mental Mastery Cheatsheet. The broader offer also includes a Synthesizer course and standalone digital products.
According to the published plans, Sloww Premium Annual costs $99 per membership billed annually. It includes premium articles and infographics, Sloww Society community and mobile app access, and the Mental Mastery Cheatsheet. Sloww Premium Lifetime costs $499 as a one-time membership with the same listed highlights. The pricing page states that Premium membership is currently sold out, while free book-summary content remains available. The annual plan has a zero-day refund period, so prospective subscribers should review the terms before paying.
Sloww’s main distinction is breadth around personal learning rather than summaries alone. The combination of a community, app, newsletter, curated recommendations, infographics, a 500-plus-concept cheatsheet, and a course gives readers several ways to engage with nonfiction ideas. Web, iOS, and Android coverage supports access across common devices, while email is the listed support channel. Readers seeking a focused growth community and guided learning resources should find the scope relevant; those who prioritize a substantially larger summary catalog, broader integrations, or more extensive support channels should consider another service.
