Listen to Instapaper — No Premium Needed
CastReader reads your Instapaper saved articles aloud with natural AI voices — covering the read-aloud feature that Instapaper charges for, for free.
The forgotten art of long-form magazine editing
A good magazine editor used to guard the reader from a writer's self-indulgence. They cut what felt clever but earned nothing. In the web era that discipline disappeared, and much long-form writing now reads like a first draft dressed up. The best publications left are the ones that still let editors argue with writers — and sometimes win.
Reads the article — Instapaper's premium-only TTS feature replaced for free
How CastReader Works with Instapaper
Get the read-aloud feature without the $59-a-year subscription
Premium Feature, Free
🔊 TTS Without the Instapaper Premium Paywall
Instapaper's built-in text-to-speech is gated behind Instapaper Premium (~$59/year). CastReader adds the same feature — one-click listen on any Instapaper article — for free. Keep using Instapaper for saving and archiving; use CastReader for the audio.
Reader Mode Friendly
Built for Instapaper's Clean Layout
Instapaper's reader view is already stripped of site chrome — which means CastReader has almost nothing to filter out. The article body is already isolated. You get the cleanest possible listen experience of any read-later tool.
Works on All Saved Articles
Web, Mobile Browser, Any Saved Format
Whatever you've saved to Instapaper — articles, blog posts, newsletters, PDFs rendered through Instapaper — CastReader reads it aloud. Works on instapaper.com in any desktop or mobile browser.
Highlights Stay
Your Instapaper Highlights Keep Their Color
If you use Instapaper's highlight feature, CastReader preserves the highlight background on the page — you listen to the full article while your saved highlights stay visible for quick review later.
Frequently Asked Questions
Everything you need to know about listening to Instapaper with CastReader
Does Instapaper have a built-in read-aloud feature?
Yes, but only in Instapaper Premium (~$59/year). The free tier has no text-to-speech. CastReader adds the same feature for free, so free-tier Instapaper users don't have to upgrade just for audio.
Is CastReader replacing Instapaper Premium, or complementing it?
For the text-to-speech feature specifically, CastReader replaces it — you don't need Premium for the audio if you use CastReader. But Instapaper Premium also has full-text search, unlimited notes, and text highlights that CastReader doesn't touch. Many users keep Premium for those and use CastReader for audio because it's faster and has more voices.
Does CastReader work on the Instapaper mobile app?
CastReader is a browser extension — it works on instapaper.com in your browser. The native Instapaper iOS/Android apps are outside the extension's scope. For mobile listening, use Send to Phone to stream audio from your browser session.
Does it read my highlights separately?
CastReader reads the full article by default. Your Instapaper highlights stay visually marked on the page, but they're not read separately — they're just part of the flow. If you want highlights-only reading, pair with Readwise Reader instead (where CastReader has a dedicated mode).
Does it handle saved PDFs and long-form content?
Yes. When Instapaper renders a saved PDF or long article as its reader-mode view, CastReader reads that rendered view. Long features (3,000+ words) work well — pair with 1.5x speed and Send to Phone for a commute podcast.
What about Pocket users migrating to Instapaper?
Pocket is shutting down in 2025 and many users are migrating to Instapaper. CastReader has you covered — it was already the primary read-aloud alternative for Pocket too, and it works identically on Instapaper.
Is it free?
