Read It, Hear It, Finally Understand It
CastReader is two readers in one. Quickread explains a hard or foreign page in the language you think in — marking the key points with a moving pen — while plain read-aloud narrates anything in natural AI voices. Free to start, no login, 40+ languages.
Stuck on a Page? Have It Explained, Not Just Read
A plain reader pronounces a dense or foreign paragraph and leaves you just as lost. Quickread is different: it works out what the passage means and talks you through it in the language you know best, while a pen circles, underlines, and highlights the key points in the original. Eyes on the page, ears on the explanation — like a tutor reading along beside you, so even a thick research paper finally clicks.
- Cross-language — reading in English? Have that French, Chinese, or German article explained in English
- A pen marks the key points — your eyes follow the moving pen, so you never drift off
- Explains the meaning, not just the words — summarizes and unpacks dense academic writing so you catch the gist fast

Hear Any AI Answer — or Have It Explained
A play button sits next to every ChatGPT, Claude, or Gemini reply. Click to listen to just that answer — no copying, no selecting — or run Quickread on a tangled explanation to get it unpacked in your language. Built for long walkthroughs, code, and analysis.

Long Read? Listen to It Like a Podcast
Drop onto a long article and press play — natural AI voices read it aloud with the current paragraph highlighted, so you can follow along while you cook, commute, or rest your eyes. Foreign-language piece? Switch to Quickread and hear it explained in your language instead.
- Smart extraction strips ads, navigation, and sidebars — just the article
- Paragraph highlighting keeps your place if you glance back at the screen
- Works on any website — news, blogs, newsletters, forums, wikis
Artificial intelligence is transforming how we consume information. From personalized feeds to smart assistants, technology adapts to our habits.
But one gap remains: long-form reading. Articles pile up in bookmarks, PDFs sit unread, and newsletters go stale.
What if you could simply listen instead? AI-powered text-to-speech turns any webpage into a podcast-like experience.
