ADNU Reader Lite is a fully-featured, browser-based ePUB reader you can embed directly on your author website, landing page, or WordPress site — in minutes, for free.
This is the actual ADNU Reader Lite — fully interactive. Page through chapters, change font sizes, enable narration. This exact experience is what your readers will see on your website.
Interactive · Tap any page edge to turn · Click the headphone icon for narration
Reader Lite packs every core reading and narration feature your readers need — out of the box, with no subscriptions or API keys required.
Full ePUB 2 & 3 support. Renders your book's internal styles, fonts, chapter breaks, and images faithfully — just as your editor intended.
Three built-in narration modes: Web Speech API (instant, free), curated Apple voices (high quality), and Aeneas word-level sync for pre-recorded audio.
Switch between paginated book mode (5.5×8.5″) and continuous scroll. Auto page-turning during narration keeps listeners fully immersed.
Readers can increase or decrease font size, toggle dark mode, and choose their reading font — giving everyone a comfortable, personalised experience.
Full table of contents with instant chapter jumping. Floating chapter indicator in scroll mode always shows readers exactly where they are in the book.
Readers can bookmark their exact narration position and return to it later — even after closing the browser. No account required, stored locally.
Set a chapter limit (1–10) so readers experience a compelling preview of your book. Once they reach the limit, they're invited to purchase — converting browsing into sales.
Natural trackpad gestures for page turning on desktop. On mobile, tap the left or right edge of the page. Navigation always feels exactly right.
Automatically detects system dark mode preference and overrides ePUB light backgrounds for comfortable night reading — no configuration needed.
No server required. No account needed. Just your ePUB file, one HTML file, and a two-line iframe snippet.
Grab the single HTML file from your ADNU dashboard or directly from GitHub. It has zero external dependencies.
Drop your ePUB file in the same directory and update one line of configuration. Set your chapter limit, voice preference, and reading defaults.
Paste a two-line iframe tag anywhere — your homepage, a dedicated book page, or a blog post. Readers see a fully interactive experience immediately.
✦ Works on any hosting
Apache, Nginx, GitHub Pages, Netlify, cPanel, Squarespace — if it serves HTML, it works.
From instant browser voices to professionally synced audio, Reader Lite supports the full narration spectrum — with no configuration needed for the most common use case.
Instant narration using the browser's built-in text-to-speech. No setup, no files, no API keys. Works on every modern browser. Great for quick reader trials.
A hand-selected list of the highest-quality voices available on macOS and iOS — Eloquence, Siri voices, and Neural TTS voices that actually sound human. Authors choose the voice that matches their book's character.
The most powerful mode. Pair your own pre-recorded MP3 narration with an Aeneas timing map, and Reader Lite highlights each word in sync with the audio — creating a professional audiobook experience directly in the browser.
