 Highly  wass a silo-based web app that allowed users to highlight and save content on web pages and within apps. Highlights on the service are cloud-synced, searchable, and shareable.

Site Death
Hi!
 * 2020-01-22: Highly emailed users the following note:

It's time to say goodbye to Highly. I'm not crying, you're crying.

To keep your highlight collection, you can download it or migrate it to another service (Instapaper or Readwise). These export options will be available through next Monday, January 27, after which your collection will be inaccessible and subsequently deleted, and the highlighter and website will no longer work.
