Merrilin Reader: Ask Anything

Merrilin AI

About this app

Read anywhere, ask anything.

Merrilin is a reader for people who care about reading. It was built by a reader who wanted the best reading experience on any device: your own books, clean typography, and your place in the book following you from phone to browser and back.

Bring your EPUBs and PDFs. Merrilin keeps your progress synced on every device, works offline, and stays out of the way so the book is the interface.

And when a passage has you stuck or curious, you can ask a question without leaving the page. Merrilin knows exactly how far you've read, so answers only draw on what you've already seen — nothing from later chapters. No spoilers, ever.

- Import and read your own books
- Distraction-free reading with themes and typography controls
- Progress synced across phone and web
- Ask questions mid-book and get spoiler-safe answers anchored to your exact position
- Keep notes and conversations alongside the book
- Reads offline; syncs when you're back

Merrilin is for fiction binges, slow non-fiction, technical books, and everything in between — anyone who wants a reader that respects the book.

What’s new

EPUB imports now recover covers from legacy wrappers and first-page artwork, repair invalid saved covers, and keep reading available when optional artwork fails. Missing and loading covers now use a clearer Merrilin-branded fallback, including grayscale E-Ink styling.
