Readwise Reader

The web application gathers articles, newsletters, RSS feeds, PDFs, EPUBs, YouTube transcripts, and Twitter threads into a single library that can be accessed offline. Users can save content from the browser via an extension, upload personal files, and subscribe to feeds, creating a unified reading queue that replaces multiple separate tools.

Reading is complemented by a highlighting system that works on web pages, PDFs, images, tables, and rich text across all device types. Highlights can be annotated, tagged, and later revisited, and the service syncs these annotations with the original Readwise platform for ongoing review and integration with note‑taking applications.

Designed for readers who handle large volumes of long‑form material, the service emphasizes powerful, first‑class annotation and a streamlined workflow that consolidates diverse content formats into one place. It is positioned as a stable, free‑beta product aimed at professionals, academics, and other power users.
