inside the card
Go deeper when a word matters
Understand the meaning in context, hear the pronunciation, and practice until it sticks.
01 / SENSE
The right word and meaning
Multiple glosses, with the one that fits this sentence surfaced first. You learn the meaning in front of you, not all of them at once.
02 / GRAMMAR
The grammar behind the sentence
Click a word and the card also names the grammar around it — the pattern, what it does, and an example. Works in English, Spanish, German, Ukrainian, Japanese, and Korean.
ProGrammar on this page
Every pattern on the page in one list, grouped by your level.
03 / VOICE
Hear it in a real voice — then say it back.
Every word and sentence plays in a natural on-device voice, and a shadowing trainer records you and lays your pitch over the model's.
04 / REVIEW
Surfaced at the exact moment you'd forget.
Every word you save comes back for review at just the right moment — powered by FSRS, a modern spaced-repetition algorithm.

on your device
Your pages stay on your device.
The reading happens in your browser. To show a word's meaning, lemmaro looks up that word — not your page — from its dictionary.
Pages are read on your device
Deciding what to highlight happens quietly in the background. Your page is read where it already lives and isn't uploaded or stored.
Words, not pages
Opening a word fetches its meaning, pronunciation, and senses by that word. For a genuinely ambiguous word, that one sentence goes along so the right sense shows.

It runs on Chrome and Firefox today — and on Brave, which installs the Chrome build.
FAQ
Questions, answered plainly.
What to expect at launch.
Is it free? Is it really launched yet?
The public store listing is being prepared. Join the launch list for one email when it is ready. Reading, highlighting, word cards, saved words, and spaced review are free. Pro adds deeper word guidance and Anki decks with audio.
Does it slow down the pages I read?
lemmaro reads the page quietly in the background, then lays its highlights over what you're already reading. The page loads as normal; the color-coding appears a moment later.
Is my reading actually private?
The reading that decides what to highlight happens in your browser — your page isn't uploaded or stored. To show a word, lemmaro fetches its meaning, pronunciation, and senses by that word; for ambiguous words it also sends that one sentence to pick the right sense. So lemmaro looks up words, not pages.
Which browsers does it support?
Today it runs on Chrome and Firefox — and on Brave, which installs the Chrome build. More browsers are on the roadmap; the wishlist is available while the public store listing is being prepared.
Which languages can I learn?
You can read six languages: English, Spanish, German, Ukrainian, Korean, and Japanese. Meanings and translations come in English, Ukrainian, Spanish, or German. Free includes one short translation per meaning; Pro adds more translations and usage notes.
How does it decide what I already know?
Every word carries a personal mastery state — new, learning, familiar, or known — and that's what drives the highlight color. As you save and review words, FSRS spaced repetition updates each word's state over time, so the highlighting tracks what you actually know, not a generic frequency list.
