Overview
Description

Instapaper lets you capture web pages, articles, and PDFs with a single click and store them for later reading on any device. Its clean, text‑only view strips away ads and formatting, making long‑form content easy on the eyes. The service syncs across iOS, Android, web browsers, and e‑readers, so you can continue where you left off whether you’re on a commute or at a desk. Premium features add unlimited highlights, full‑text search, and custom fonts for a personalized reading experience.

Readwise Reader is a unified reading app that pulls articles, PDFs, EPUBs, RSS feeds, YouTube transcripts, and social threads into a single distraction-free inbox. It treats annotation as a first-class feature, letting readers highlight text, images, and tables and sync those highlights across devices and note-taking tools. The app can also function as a full EPUB reader for DRM-free ebooks, complete with annotation support, and adds AI features like Ghostreader for summarizing and answering questions about what you're reading, plus a spaced-repetition Daily Review that resurfaces old highlights over time.
