What Readwise Reader does well

Ghostreader, its AI assistant, can answer questions, define terms and simplify language. There is a 30-day free trial, after which Reader is part of a Readwise subscription.
Where Kajr fits instead
Kajr is for people who want to save first and think later, from their phone, without setting up a reading workflow. It is free to save, needs no account, and keeps your library on your device. Each save arrives with a summary, key takeaways, a quality score, action items and tags, and you can ask questions across the whole library.
Your library can sync to your own Google Drive, and you can export it to a file, an Excel spreadsheet or a Chrome bookmarks file. It is not an RSS reader or an EPUB app, and it has no desktop app.
