Readwise. Quiet paper-white, serif headlines, and one blue pen.

Readwise presents a literary productivity workspace: a near-white canvas with a single editorial blue accent and warm yellow highlighter washes that literally visualize the product's purpose. The type system pairs a transitional serif (Charter) for headlines with a humanist sans (Mulish) for everything else, creating a bookish-but-modern reading-room atmosphere rather than a typical SaaS dashboard feel. Surfaces are flat and quiet — cards float on a cool paper-white (#f1f5f8) with hairline borders, almost no shadows, and rounded corners that feel like printed cards rather than app tiles. Yellow (#fff7ca) functions as a literal highlighter behind in-line emphasized text, not as a decorative accent — the product's identity IS the act of marking what matters. Components stay compact and text-forward, with one filled blue button carrying all the weight and everything else rendered in ghost or text-link form.
