Okuzeka
Tap words to see their meaning while reading pdf and epubs.
Read foreign-language PDFs and EPUBs without leaving the page. Tap any word and Okuzeka uses sentence context to show the most relevant meaning, then saves it for review—so every book becomes a vocabulary course.
Hi Product Hunt! 👋
I’m Ali, the founder of Okuzeka.
Okuzeka started with a very simple problem: I wanted to read books in English, but every few sentences I had to stop, open a dictionary, search for a word, inspect ten possible meanings, return to the book, and then try to remember what the paragraph was about.
At some point, I realized I was spending more time operating dictionaries than actually reading.
So I built Okuzeka.
You upload a PDF or EPUB, tap an unfamiliar word, and Okuzeka shows the meaning that best fits the sentence. No leaving the page. No copy-pasting. No dictionary giving you twelve definitions and wishing you good luck.
I tested it by reading the Dune series in English, which was either a very ambitious product test or an unnecessarily aggressive vocabulary challenge.
During the first book, I was tapping so many words that I sometimes wondered whether I was reading Dune or playing a very slow word-clicking game designed by Frank Herbert.
But from the second book onward, something changed: the number of words I needed to tap noticeably decreased.
The same words kept appearing in new sentences, and eventually they started sticking without me deliberately memorizing them. Apparently, vocabulary learns that resistance is useless if it follows you through several hundred pages.
That is the core idea behind Okuzeka:
Instead of memorizing isolated vocabulary lists, you meet words repeatedly inside stories you actually want to read.
So yes, Okuzeka is technically an e-book reader.
But emotionally, it is a vocabulary-learning monster wearing glasses and pretending to be a library.
The product is still evolving, and I would love your honest feedback:
• Does tapping a word feel natural?
• Would you use it to finish an entire book?
• What should we build next: better flashcards, reading statistics, pronunciation, or a feature that politely asks difficult authors to use simpler words?
Thanks for checking out Okuzeka!
