Omnivore was the open-source read-it-later app a lot of people loved, and it shut down in November 2024 when the team joined ElevenLabs. Most replacements try to rebuild all of it. ceevo goes the other way.
Omnivore was a reader: highlights, labels, newsletters, an offline text view. ceevo is a keeper: links and notes in folders, with any folder shareable as a page. If you mostly highlighted, ceevo will feel too small. If you mostly saved, it will feel like relief.
Some people used Omnivore as a serious reading tool: newsletters piped in, highlights synced to Obsidian or Logseq, labels for everything. If that is you, you want a reader, and Readwise Reader is the closest thing still standing.
Other people used Omnivore because it was a clean, free place to save a link from the phone. That group does not need highlights. They need the link to still be findable in three months, and they need to be able to hand a list of links to someone else without a spreadsheet.
Keeps: saving in a second from a laptop or a phone, a title and preview pulled automatically, folders you name yourself, search across everything, notes alongside links, and a public page for any folder.
Leaves out: reader view, highlights, RSS, newsletter inboxes, labels, self-hosting. Not because they are bad, but because a tool that does all of that becomes a second inbox, and ceevo is trying not to be one.
Omnivore let people export their library before it closed. ceevo does not have an importer yet, so the honest answer is that you would re-save what still matters by hand. For most people that is a short list, and a good moment to let the rest go.
