Listen to Nautilus
Turn any nautil.us article into audio. Open the piece in Chrome, click CastReader, and listen from the dek through the last paragraph — with paragraph highlighting. Nautilus is the science longform magazine.
Why Listen to Nautilus with CastReader?
Nautilus features are 3,000–8,000 words of narrative science writing. They're the magazine-form of the best lab story you've ever heard.
Full Article
Dek, Byline, Body
CastReader reads the dek, byline, and full body in order. Nautilus's 'Chapter' structure (features are broken into 2–4 numbered parts) is respected — the audio pauses briefly at each chapter break, matching how the piece is meant to be read.
Narrative Science
For Stories, Not Textbooks
Nautilus writes science as narrative — a scientist, a question, a discovery. Audio matches the genre. You listen the way you listen to This American Life, but the subject is black holes or bacteria or the nature of time.
Clean Audio
Skips Subscribe Walls and Newsletter Pitches
Nautil.us has a metered-access model with subscribe banners, newsletter pop-ins, and 'Save to Reading List' widgets. CastReader reads only the article body — when you're a subscriber the full feature plays end to end, when you're not it plays the excerpt visible in your browser.
100% Free
Unlimited Science Listening
No signup, no quota on the extension side. A Nautilus feature is a 30–60 minute listen at 1.5x, which is perfect for a walk or an errand run.
Frequently Asked Questions
Everything about listening to Nautilus with CastReader
How do I listen to a Nautilus article?
Open the piece on nautil.us in Chrome (URLs look like /issue/123/name/the-title). Click the CastReader icon. It reads dek, byline, and body.
What about the subscription wall?
CastReader reads what your browser rendered. Nautilus Prime subscribers see full features in the DOM — we read them. Non-subscribers see the free excerpt — we read that. We don't bypass subscription walls.
Does it handle the 'Chapter' structure?
Yes. Nautilus features are often broken into numbered chapters or sections with their own subheads. CastReader reads each subhead inline and pauses briefly at chapter transitions, so the audio structure matches the printed structure.
What about science illustrations?
Illustrations and photographs are skipped because audio can't represent them. Caption text under images is read as prose because captions often contain context the article depends on.
Does it handle Nautilus columns?
Yes. Columns (Ingenious, Facts So Romantic, etc.) read the same way as features. They're shorter — typically 1,500–2,500 words — so about 12 minutes at 1.5x.
What gets skipped?
Subscribe banners, newsletter prompts, 'Save to reading list' widgets, footer chrome. Only the article body reads.
Can I adjust reading speed?
Yes. 0.5x through 3x. Science longform often wants 1.5x — fast enough to keep narrative momentum, slow enough to follow the technical ideas when they land.
Is it free? Any limits?
CastReader is completely free with no limits. Nautilus itself has a subscription tier — the extension reads whatever text your browser has loaded, which for subscribers is the full article.
