Every word you find,
saved in one place you'll actually use
Lexog turns the words, phrases, and idioms you find in books, conversations, work, and videos into a vocabulary system you can review, remember, and actually use.
You already have a vocabulary.
It's just scattered everywhere.
A word from a business call. A phrase from a podcast. An idiom your coworker used that you quietly Googled later. Most of it ends up in Notes, screenshots, half-read Reddit threads, or nowhere at all — and by the time you'd actually use it, it's gone.
Flashcard apps don't fix this. They hand you words that have nothing to do with your life, in an order that feels random, disconnected from where you actually found them.
Lexog is where your words actually live
Save a word the moment you find it. Add meaning, context, source, and category. Organize everything by your own categories such as Business, Retail, Travel, or whatever fits your life. Then review it when it matters, instead of following a random deck built for someone else.
It's not a flashcard deck. It's your personal vocabulary system, built from your own life.
“Your words, organized the way you actually think about them.”
Everything you need. Nothing you don't.
Built around the vocabulary you actually collect — not the words someone else decided you should learn.

Questions
Lexog is built around English vocabulary right now, but you can save words and phrases in any language, the organizing and review system works the same either way.
No. Flashcard apps quiz you on someone else’s word list. Lexog starts with your words - the ones you actually found in your own life, and lets you review those, in the order and category you choose.
Yes. Save a text you're reading, highlight the words or phrases worth keeping, and add them to your vocabulary list with context intact.
It's a way to connect your Lexog vocabulary to Claude. Once connected, you can ask Claude to quiz you, explain a word, generate examples, or build a review plan — all using your own saved words.
No. Saving and reviewing words takes no setup at all. The Claude integration involves one extra step (generating and entering a key), and Lexog walks you through it.
Not yet. Lexog is iPhone-only for now, with Android planned for the future.
