+      Omnivore Digest is a free daily digest of your best recent library items. Omnivore

+      Note that if you sign up for Digest, your recent library items will be processed by an AI
+      service (Anthropic, or OpenAI). Your highlights, notes, and labels will not be sent to the AI
+      service.
+
