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.
Omnivore has shut down and is no longer available. Any of the active alternatives is a safer bet.
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. Free users can also import bookmark exports from Pocket, Instapaper, Omnivore, Raindrop.io, Pinboard, Wallabag, Safari, OPML readers, plain CSV/TSV files, and X bookmarks exported by the Keep extension. Semantic search runs across everything you've saved.
Omnivore was a free, open-source read-later app that did everything right on paper: RSS feeds, newsletter inbox, PDFs, highlights, labels, filters, rules, full-text search, a GraphQL API that returned markdown, and sync with Logseq, Obsidian, and Notion. It ran on iOS, macOS, Android, web, and extensions for Chrome, Firefox, Safari, and Edge. It shut down on November 15, 2024 after ElevenLabs acquired the team for their ElevenReader TTS product. The cloud service deleted all user data; the open-source codebase still lives on GitHub for anyone who wants to self-host.
