| What it is | Instapaper monetizes by offering a free article-saving service and charging for premium features via subscription. | Readwise is a bootstrapped paid reading tool (including the Reader app) that survived a category where free models systematically die, by combining paid-only subscriptions, a two-sided integration ecosystem, and nine years of endurance that made it the named heir in competitors' shutdown notices. |
