For readers

Become a deeper reader.
Quietly.

The words you meet while reading should stay with you. Lexiora is the quiet companion that makes them.

ephemeral /ɪˈfɛm(ə)rəl/

lasting for a very short time

A word stays ·

Vocabulary isn't memorized.
It's returned to.

Two systems do the returning. The context that held the word the first time, and the spacing of each time after. Lexiora holds both — the sentence where you found it, and the moment the forgetting curve bends. Neither one alone is enough.

What changes, slowly.

You finish the book.

The novel you started in another language stops being the one you'll get back to. You're already in it.

The words stay.

Not the ones you crammed. The ones you met. They come back the next time, and the time after.

You sound like the reader you are.

Your reading life shows up in how you write, how you speak, how you think. Quietly.

Look it up. Return to it.

Step 1 · You look it up

“The candlelight cast ephemeral shadows against the manuscript pages.”

Picture morning mist disappearing before your coffee has time to cool.

A few days later, in your daily review.

Morning mist, before coffee.

For readers who aren't done growing.

Reading in a second language.

Novels. The Economist. Der Spiegel. If you're reading in a language you're still growing into, Lexiora keeps pace. Every lookup becomes a building block, not a detour.

Growing your native vocabulary.

The words you meet in books should be yours. Lexiora captures the ones that slip and brings them back until they don't.

It travels with your reading.

Frequently asked.

What languages does Lexiora work with?

The extension works on any source language. You choose your native language for definitions — Lexiora adapts.

What happens to the text I look up?

When you select a word or sentence, only the highlighted text — plus the surrounding sentence for single-word lookups — is sent to our servers. We use third-party AI providers for generation, trusted dictionary APIs for sources, and YouGlish for pronunciation. We don't log page URLs. Each lookup is saved to your own account so you can review it later; it isn't retained as anonymous server logs.

How does review work?

Spaced repetition. Short sessions. The algorithm picks what you're about to forget and shows you those words, not everything.

Can I export my saved words?

Yes — CSV export is available today. Anki export is on the roadmap.

Will it work on Kindle or Kobo?

Not yet. E-reader support is on the roadmap.

Is there a free version?

Everything is free during beta. A Pro tier is coming; beta users get a discount when it ships.
