How EnrichReader works

It only knows
what you've read.

EnrichReader keeps track of where you are in the story. It shows you the characters, places and lore you've already met, and keeps everything after that hidden.

  • Ch. 5Victor brings him to life, then flees in horror.
  • Ch. 12Learns his first words by listening through a gap in a cottage wall.
  • Ch. 24Revealed in a chapter you haven't read.
Every fact carries the chapter that reveals it,
and where you are decides which ones you see.
Nothing past your chapterEvery fact cites its chapterYour book stays on your device

01 The one rule

Nothing past
your chapter.

EnrichReader stores what it knows about a story as small facts, and each one is tagged with the chapter that reveals it. Open a profile and you get the facts from chapters you've read. The rest stays hidden.

The app remembers the furthest chapter you've reached, so going back to reread an early scene doesn't hide anything you've already seen. If it can't work out where you are, it shows you nothing at all.

02 Two ways to use it

In the app, or beside your book.

Both follow the same rule. The difference is where you read and how the companion finds out where you are.

AInside your reader

The app follows you

Read your own book in EnrichReader with a matching Skin. The app sees where you are as you turn pages, so the profiles keep up without you doing anything.

BAlongside your book

You tell the guide

Read wherever you like and keep a reading guide open in your browser. You tell it which chapter you're on, and it shows only what came before.

03 In the app

Four steps,
then you're reading.

  1. 1

    Bring your book

    Import a DRM-free book file you own. The app keeps it on your device and opens it there, and you can read without an account. The reader works fine without a Skin, too.

  2. 2

    Find its Skin

    A Skin is the companion for one story: its characters, places, organizations and lore, each fact tagged with a chapter. We prepare Skins ahead of time for partner series. Sign in and search the catalog. If your book isn't there, ask for it, and the app will let you know when it's ready.

  3. 3

    Match it to your copy

    The first time you open the book, the app lines the Skin up with your file, chapter by chapter, on your device. That takes a couple of minutes and only happens once. If your edition is too different to line up, the app tells you rather than matching the wrong chapters.

  4. 4

    Read, and tap a name

    Names the Skin knows glow in the text. Tap one to see who they are as of the chapter you're in. When someone shows up for the first time, the app tells you their details unlock in later chapters.

If you'd rather try it before importing anything, the app comes with a sample book, Initiation Protocol, already matched to its Skin, plus a short tour.

04 While you read

A companion that
reads along with you.

Profiles that grow

Each profile tells you which chapter it's current as of. When a chapter changes what you know about someone, you can see exactly what that chapter added.

Appearances so far

A timeline marks the chapters where a character shows up. The ones you haven't read stay locked. You can tap to peek, but the app checks with you first.

The Codex

The Codex collects everyone and everything you've met and flags what's new since your last session. Its search only finds people you've already run into.

Welcome back

If you put the book down for a while, a briefing tells you where you are, how long it's been and what was going on, including the current arc and any leads still open. It shows up when the Skin has story data.

Atmosphere

Weather and light play behind the text, and artwork shows up at key scenes when you reach them. It depends on the Skin, and you can switch the effects off in settings.

Something look wrong?

Every profile lets you report a mistake. The report sends us that chapter's text, the titles and your note, and we fix the Skin.

05 How a Skin is made

Built from the book,
before you open it.

We make Skins ahead of time for partner series, from the book's text, using EnrichReader's own AI model on our own hardware. Every fact it records gets the chapter that reveals it, which is how the app knows to hold it back until you get there.

We never send your own book to it. A Skin can still get things wrong, and when you report a mistake, we fix it.

06 The spoiler shield

You decide how
careful it is.

Pick a default for all your books, or change it for one. If you choose something looser than where you are, the app asks before showing you more.

Strict
Only what you've read, up to your chapter.
Volume
Everything up to the end of the volume you're in. Useful if you've already read ahead somewhere else.
Off
Everything the Skin knows, for rereads or once you've finished the series.

07 In the browser

Reading guides:
you pick the chapter.

A reading guide sits next to whatever you're reading, whether that's a paperback, another app or a library copy. Choose the letter or chapter you're on, and the guide shows characters, places and story context from the sections you've finished. You don't need to install anything or sign up.

The link remembers your position, so a bookmarked guide opens where you left off. When you finish a section, move the picker forward. The first guide is Mary Shelley's Frankenstein.

08 The fine print

Good to know.

Books, accounts, privacy and cost.

Your book
The reader opens DRM-free book files you own. EnrichReader doesn't sell books, and you need a Skin for your story to get the companion features.
Privacy
Imported books stay on your device. Sync covers your library, reading positions and settings, but never book text. Reporting a chapter problem does send that chapter's text. The privacy policy has the details.
Accounts
You can read without an account. You need one to install Skins and to sync between devices.
Offline
Once your book and its Skin are on your device, you can read offline. You need a connection to install a Skin.
Cost
The app is free to download and has no in-app purchases.
