About Instapaper
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.
About Keep
Keep saves articles, posts, videos, feeds, files, and notes as clean Markdown. You can read the library yourself, search it, export it, or let Claude Code, Cursor, Codex, ChatGPT, and other clients use the same context over MCP or CLI. Starter is free for bookmark saves and a limited note library. Personal is $10/month and adds full-content Markdown, search, sources, automations, and agent access. X bookmark sync is a $5 add-on for automatic private bookmark import.
