Who should pick Readwise
You highlight and annotate deliberately. You already finish what you start. You want those highlights in Obsidian or Notion.
Reader is the best read-it-later app for people who read. Daily Review keeps highlights alive. The stack is mature.
Who should pick Dewey
You save faster than you can read. Your tabs and bookmarks overflow. You need answers from what you saved, not another place to store it.
Dewey reads the stream for you. The chat digest is a parallel habit to Daily Review (same cadence, different object). Ask questions anytime.
Can you use both?
Yes. Many people do.
Dewey Follows your sources (newsletters, podcasts, YouTube, X bookmarks) and reads the stream continuously. When something matters, Ask in chat.
Readwise keeps the highlights from what you finish. The library stays searchable.
Different jobs. No overlap if you treat Dewey as the stream reader and Readwise as the highlight vault.
Habit Dewey steals (without copying the product)
Readwise's Daily Review is a strong daily resurfacing habit. Dewey's version is a digest of sources you Follow, delivered in Telegram or iMessage.
Same idea: show up every day. Different object: Follow'd sources, not a highlight OS. Many people can use both.
