For readers

Read the book.
Keep the words.

Look a word up while you're reading and it's already saved — with the sentence you met it in, and a card that comes back exactly when you'd have forgotten it.

How it works

Three things, and you only do the first one.

The habit dies at the "add to deck" button, so there isn't one. Searching a word is saving it.

Look it up

Type it, tap it in Reading Mode, share it from Apple Books, or double-click it in your browser. However it arrives, it's saved.

The sentence comes with it

A definition read once decays fast. The same definition anchored to a sentence in a book you remember reading lasts far longer, so Wordhoard keeps both.

It comes back before you forget

Cards are scheduled with FSRS, the same algorithm serious flashcard users switched to. Words you know go quiet. Words you keep losing come back sooner.

Definitions worth keeping

A dictionary can define a word. It can't tell you what it's doing in your sentence.

This is the whole reason Wordhoard exists. When the dictionary doesn't help, ask for the meaning you actually needed.

Wiktionary, on “arithmetic”

Of a progression, mean, etc, computed solely using addition.

Correct, and useless to someone reading Crime and Punishment.

Wordhoard, on your sentence

Basic maths — adding, subtracting, multiplying, dividing.

Here it's figurative: a cold weighing-up of lives, as if they were sums. From “It was simple arithmetic, he told himself: one life against a hundred.”

What's in it

Built for people who read difficult books.

📖

Reading Mode

Paste a passage or photograph a page, then tap any word. The sentence around it is captured with it, so the card knows where you were.

🔎

Words from a book

Name what you're reading and get the words in it you probably don't know — pulled from the book itself, not from a list somebody else made.

📥

Kindle and Kobo import

Your e-reader has kept every word you ever looked up, and the sentence you met it in. Wordhoard turns years of that into a library in one go.

🌐

Browser extension

Double-click a word on any page. The definition appears where you're reading, and it's on your phone by the time you pick it up.

✍️

Write it yourself

A name, a piece of jargon, a word no dictionary has. Type what it means in your own words and it becomes a card like any other.

🗂️

Shelves, not folders

Words file themselves under the book they came from, so a category is a thing you read rather than a thing you had to maintain.

Sharing

Make the flashcards for them.

Write what a word means in the words your child will actually understand — something no dictionary can do, because it depends on knowing the child — and it lands on their phone as a card to learn.

Nobody can reach them uninvited

There is no directory, no search and no username. The only way to connect is a code typed into their own phone, by them. It lasts a day and works once.

It only goes one way

You can send words to them. They can't see your library, your reviews, or anything else about you — and neither can anyone else.

Either of you can stop it

One tap, no confirmation from the other side, effective immediately. Words already sent stay theirs.

You can't undo their progress

A word they already have is left alone — their meaning, their card, their history. Every card you send starts from new.

We never learn your child's name. It's stored on your phone and nowhere else — our server only knows that two accounts are connected and what you asked to be called. How that works.
