Different tools for different needs

Readwise Reader is an all-in-one reading app that combines RSS feeds, read-later articles, PDFs, EPUBs, and email newsletters with deep highlighting and annotation. It's built for people who want everything in one place and care deeply about taking notes on what they read. NewsBlur is a dedicated RSS reader built for people who follow many feeds and want intelligent filtering to surface what matters. If your primary need is RSS with powerful training and filtering, NewsBlur is the sharper tool for the job.

Intelligence training vs. manual curation

NewsBlur's intelligence training system lets you highlight or hide stories based on author, tag, title keywords, full text content, URLs, and regex patterns. Over time, your feeds become personalized without any algorithmic black box. Readwise Reader has no equivalent system. You manage your reading through manual triage, filters, and folder organization. For high-volume reading across hundreds of feeds, NewsBlur's training is a significant advantage.

Free tier and open source

NewsBlur offers a free plan with up to 64 sites, and every new account gets a 30-day premium trial. Readwise Reader requires a paid subscription ($96/year) with no free tier. NewsBlur is also fully open source under the MIT license, so you can self-host your own instance, contribute to development, or audit the code. Readwise Reader is a closed-source service.
