A reading companion for parents & kids

Every unfamiliar word,
a moment to grow.

BookWords turns hard-to-read words into instant flashcards that build vocabulary for early readers — captured in a glance, without ever breaking the moment between parent and child.

How it started

It began at bedtime, one hard word at a time.

Every parent who reads with a child knows the pause. You're a few pages into the story, the room is quiet, and your child hits a word they don't know — craning, luminous, reluctant — and looks up at you.

In that instant you have two bad options: stop the story to explain and lose the moment, or skip the word and lose the chance to teach. What if there were a third way — one that captured the word in a heartbeat and kept the story going?

That question became BookWords. Point your phone at the word, and it quietly becomes a flashcard your child can review later — a definition they can understand, the sentence it came from, how to say it, words like it. The reading never stops. The learning never gets lost.

The goal

One word becomes a card worth keeping.

Not a dry dictionary entry — a small, thoughtful card built for a child, with everything they need to truly learn the word and nothing they don't.

The definition — clear and sourced, the thing to memorize.
A kid-friendly explanation — the same idea, in words a child owns.
How to say it — a simple respelling, never confusing symbols.
The sentence from the book — the word in the world it was met.
Synonyms — the neighborhood the word lives in.

The idea that changed everything

Don't guess the word.
Confirm the one you already see.

Early on, the camera tried to be clever — snap a photo, guess the word, make a card. It felt like magic when it worked and a mess when it didn't. So we flipped the whole idea on its head.

Before · detect & create
The app took a photo, tried to extract a word on its own, and created a card. When it guessed wrong, the parent was stuck with a bad card and a broken moment.
Now · confirm & assist
The phone is already reading the page. So it simply shows you the word it sees and lets your eye confirm or fix it before saving. The human is the source of truth; the app is the fast, quiet assistant.

A small shift in philosophy, a huge shift in trust. The app stopped deciding — and started assisting.

Try it yourself

The original prototype — still playable.

This is the very first interactive prototype that started it all. We kept it exactly as it was, so you can tap through the whole experience — capture, library, flashcard review, and the story of where the idea began.

02
Native build
Rebuilt from the ground up in Swift & SwiftUI — Apple's own tools, for a fully native iPhone experience.
03
TestFlight beta
Onto a real iPhone through Apple's beta program — where the camera meets real books, real light, real hands.
04
Iterating
Round after round of real-world testing — refining the capture, the review, and the words themselves.

Where we are now.

BookWords is a real, native iOS app, testing on TestFlight today. The camera captures live words, cards are built from real dictionary sources, and the whole experience works right on the phone — with the parent and child never leaving their book.

We're refining it every week, guided by real reading sessions. A wider release will follow.
