Turn every word you look up into a word you actually know.
Your Kindle quietly saves every word you stop to look up. Vocabull turns that list into a quick, addictive game - so the words you cared about enough to check finally stick.

You look them up. Then you forget them.
Every time you tap a word while reading, it gets saved to a list you'll probably never open again. Hundreds of words - gone by the next chapter. Not because you're not smart enough. Because nothing ever made you use them again.
That's the whole problem. And it's a small one to fix.How it works

Why it works on you
It doesn't feel like studying. It feels like winning.
Built around YOUR words
No generic, forgettable word lists. You learn the vocabulary from the books you actually chose to read.
Five minutes is enough
Bite-sized rounds you can knock out in a queue, on the couch, or waiting for the kettle. Progress without the homework.
It gets smarter about you
Vocabull notices which words trip you up and quietly brings them back until you've nailed them.
Streaks, wins & a proud bull
Keep your streak alive, rack up wins, and actually feel your vocabulary getting bigger.
The simple science
Reading a word once doesn't make it yours. Recalling it does.
You can read a definition ten times and still blank on it tomorrow. The thing that actually locks a word into your memory is pulling it back out yourself. Vocabull is built around that one idea - it makes you remember, not just re-read.
Quick questions
What is Vocabulary Builder?+
When you press and hold a word on your Kindle to see its definition, Kindle saves that word to Vocabulary Builder. Vocabull turns that list into quick practice.
Do I need to be online to play?+
Yes. You can play anywhere your phone or computer has internet. Vocabull runs in your browser, so a mobile signal or Wi-Fi connection is enough.
Can I use it on my phone?+
Yes. Once your words are imported, you can play on your phone or computer anywhere you have internet.
Is my reading data private?+
Your word list is yours. We only use it to build your game - we don't sell it or share it.
