Both tools do their category well, but the specifics differ. Here's what each one is good at and where it tends to fall short.
Instapaper is one of the original read-later apps, still going strong after Betaworks took it back from Pinterest in 2020. The product has always been sharp on one thing: save a web page, read it later in a clean typographic view. Free tier gets you unlimited saves, folders, tags, sync across iOS/Android/web, and a public API. Premium at $5.99/mo or $59.99/yr layers on full-text search, permanent archive, PDF reader, Kindle send, AI voices, and speed reading. Most of the product has shipped in a long tail of small updates rather than big reinventions. The recent wave added tags across every platform, highlights on the open web via the browser extensions, and send-to-Kindle right from the extension.
Readwise Reader is the reading companion to Readwise's highlight sync service. It handles articles, PDFs, EPUBs, emails, tweets, and YouTube transcripts in one inbox, with a Ghostreader AI copilot for summaries, definitions, and Q&A. Highlights sync to Notion, Obsidian, Logseq, Roam, Evernote, and Airtable. It ships as web, iOS, Android, and browser extensions, with a public REST API for scripting. Pricing is $9.99/mo billed annually (or $12.99/mo monthly) as part of the Readwise Full plan, which includes the highlight sync service. A 30-day free trial is available.
