Vocab from a song

Paste a song. Get a deck.
Review when you'd forget.

Type a song title. Lexido finds the lyrics, lemmatizes the words against your existing deck, and offers cards for the ones you don't know yet. Conjugated forms in the chorus match back to citation-form cards. The slop is filtered out.

  • Per-language tokenization so 食べた matches 食べる
  • Native audio for every new word from the lyric
  • Edit anything before it lands in your queue

How it works

Three steps to a deck you'll actually review.

No onboarding video. No 14-step setup. The whole flow takes under two minutes.

Pick a language

Japanese, Korean, or Spanish at launch. Switch any time without losing progress. More on the way.

Build your first deck

Browse a curated starter deck or describe what you want to learn. Lexido drafts cards with sentences, audio, and images.

Review when it's due

Lexido reminds you when cards are ready, then catches the schedule up when life gets in the way.

Watch it generate

Decks from anything you'd actually want to learn.

Describe the deck in plain English. Lexido drafts cards with real example sentences, native pronunciation, and an image to anchor the meaning. Edit anything before it lands in your queue.

Sentences read like things people actually say. Readings, register, and gender match. No AI slop.

Review a card

Word, image, sentence, native audio, then rate how it went.

Pick a language

Japanese, Korean, or Spanish to start. Switch any time.

Your queue at a glance

What's due today, what's coming up, which deck you're in.

Start studying

Tap into any deck. Lexido picks the cards that are due.

Smart placement

Tell Lexido what you already know. It skips the easy stuff.

Settings, not knobs

Daily new-card cap, language, account. Nothing else to tune.

How memory works

Spaced repetition, done properly.

Your brain forgets on a curve. Lexido models that curve per card and schedules the next review at the moment you're about to lose the word. Get it right, the gap widens. Get it wrong, it tightens. Within a week the queue matches your real memory, not a one-size-fits-all interval.

The forgetting curve
Memory fades. Reviews flatten it.
Without a review, recall drops fast. Each successful review pushes the curve out.
Memory without review Memory after a good review Review moment
100% 50% 0% Day 0 Day 4 Day 10 Day 35 You review here memory resets to full after review sticks for longer no review word fades Days since you learned the word
FSRS-5 scheduler

The state-of-the-art spaced-repetition algorithm. No manual tuning, no Leitner box ritual.

Native audio and image

A picture and a native pronunciation on every card. Cached so repeat words load instantly.

Per-language tokenization

Conjugated forms in lyrics match back to the citation-form cards in your deck.

What's in v1

Five things that make it different.

Everything below is in the v1 app. Nothing is a roadmap promise.

Reviews that actually stick

FSRS-5 scheduling models how memory decays for each card and picks the moment you're most likely to recall it. No fixed intervals, no manual tuning, no daily Leitner box ritual.

Cards from a theme

Type "kitchen verbs in Spanish" or "travel vocab for Japan". You get back a deck with example sentences, audio, and images.

Vocab from songs you like

Paste a song title. Lexido finds the lyrics, matches them against your deck, and offers cards for the words you don't know yet.

Image and audio per card

Every card has a picture and a native pronunciation. Pictures help words stick. Audio trains your ear.

Coming from another app

Drag in a .apkg file and Lexido pulls in the cards and media. Old review history doesn't carry over, but you don't need it. FSRS-5 figures out your schedule within a week.

Questions.

How much does Pro cost? +

Which languages are supported? +

Japanese, Korean, and Spanish at launch. More are on the roadmap, drop a line at support@getlexido.com if you want a specific one.

Will my decks sync across devices? +

Yes. Cross-device sync is coming in an early update. Sign in with Apple and your decks and review history follow you between iPhone and iPad.

Can I move over from another flashcard app? +

Yes, if it exports .apkg (Anki and most of its forks do). The cards and media come across. Review history doesn't, but FSRS-5 calibrates within a week of normal use.

Where does my data live? +

On your device, with optional iCloud sync once you sign in with Apple. Generated card content is cached anonymously on our backend so future requests for the same word are instant.
