Omnivore

Omnivore is an open-source read-later and feed reader that supports article saving, newsletter forwarding, and highlight export to multiple note-taking apps. It is free and self-hostable. Compared with Matter, it provides strong integrations and offline capabilities but currently has a less polished mobile experience and fewer built-in audio options. It suits technically inclined users seeking customization over Matter's award-winning design and transcription features.
