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.
Keep is a save-anywhere tool built around one idea: everything you capture should be available as clean markdown that an AI agent can read. Articles, tweets, YouTube videos with transcripts, GitHub stars, newsletters, RSS, and plain URLs all land in the same searchable library. People read their library in a clean in-app feed. Agents read it through the API, CLI, MCP server, and Claude Code skill, so Claude Code, Cursor, ChatGPT, and other tools can work against the library directly. Auto-sync pulls from RSS, YouTube, X bookmarks, GitHub stars, and newsletter inboxes on a schedule, so the library stays current without manual work. Semantic search runs across everything you've saved.
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.
