Wordseed: Vocabulary Builder

Remember & use English words

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Words you meet, words you use. Wordseed brings each word back right before you'd forget it, then has you write with it. New: Word Sprint, a 2-minute game from your words. Most vocabulary apps hand you a list. Wordseed does the opposite: you type in the words you actually met — in a book, a meeting, a song — and it brings each one back right before you'd forget it. FIVE A DAY BY DEFAULT Five new words a day is the default because it's a pace you can keep — small enough to survive a busy Tuesday, and still 1,800 words a year. Exam coming up, or a list to bring over? Wordseed Pro lets you add up to 30 a day. YOU WRITE THE MEANING, NOT A DICTIONARY Every card is three things you type yourself: the word, what it means in your own words, and a sentence you'd actually say. Copied definitions don't stick — your brain files them as someone else's. THE SAME WORD GETS HARDER OVER TIME Wordseed tracks how strong each memory is and picks the exercise to match. You never pick a difficulty: - Week 1 — just recognise the word - Week 3 — drop it into a sentence, with the ending changed - Month 2 — write your own sentence using it - Month 4 — write a paragraph using it alongside other words you've mastered A card only ever climbs one level per review, so nothing arrives before you're ready. SCHEDULING THAT ISN'T GUESSWORK Wordseed runs FSRS, the open-source spaced repetition algorithm. Nothing is hidden: every card tells you how likely you are to still remember it, and Stats shows your streak, a 12-week heat map, and a day-by-day log. AI THAT CHECKS YOUR SENTENCE Write a sentence, tap Check with AI, and find out whether it actually works — and if a native speaker would say it differently, what they'd say instead. The explanation comes back in your native language, so the correction never gets lost in translation. WORD SPRINT A two-minute game made from your own words: match each word to the meaning you wrote, then race 60 seconds to pick the right one. It never touches your review schedule, so play as often as you like. A NEW PASSAGE EVERY DAY Today's Read gives you one short passage a day. Tap any word you don't know and it becomes a card, with the sentence it came from. REMINDERS AND WIDGETS One reminder a day, at a time you pick. A widget keeps one of your words, with your meaning, on your Home or Lock Screen. YOUR WORDS STAY YOURS No preset packs. No word is ever locked behind a paywall. If you stop paying, every card you added stays, stays reviewable, and keeps its full history. FREE - 5 new words a day, all four exercise levels - 2 AI sentence checks a day, and 3 AI suggestions to try - Today's Read, Word Sprint, reminders, streak and full stats - A copy-the-prompt button, for checking sentences in a chatbot you already use WORDSEED PRO - 30 new words a day - AI sentence checks and suggestions for everyday use (up to 100 a day) - Dictionary definitions on every card, in English and your language - Synonym and spot-the-mistake drills, once a word is nearly yours - Bring an existing list over: import up to 200 words at once - A new short story from your Word Sprint words, every day PRIVACY No ads. No third-party tracking or analytics SDK. The sentence you send to AI is checked and discarded — it is never written to our database. Delete your account from inside the app and everything goes, immediately and permanently.

Your words, now on your phone's screen - not only inside the app. WIDGETS "Your word" puts one of your own words, with the meaning you wrote, on your Home Screen or Lock Screen, and changes it every two hours. A word that is about to come up for review never shows there, so your next review is still real remembering. "Due for review" shows how many words are waiting and opens your review in one tap. Not sure how to add one? Profile > Add a widget shows you, step by step. WORD UPGRADES Learning an academic word like "mitigate"? Its card now shows the everyday word it can replace: instead of "reduce". And once you know an everyday word well, its card points you to the stronger one. Tap the line for a short note in your own language on when each one fits - the everyday word is never wrong. CLEARER CARDS Wordseed has its own typeface now, the same on every phone. The word you are learning is bigger, with its part of speech, word level (A1 to C2) and pronunciation right under it - tap the pronunciation to hear it. After you flip a card, the definition, your meaning and the example appear one after another. A BETTER FIRST DAY New accounts no longer start with an empty deck: the last step of setup is picking your first three words, and your first review starts right after. CLEARER FREE TRIAL The upgrade screen now shows the yearly plan's free trial step by step - today, before it ends, and the date billing starts, with your local price. And it only offers a free trial when you can still get one. PRIVACY Our privacy policy now also says that the app notes which parts of it you use (at most once a day for each part, never what you type), and that widgets keep a copy of a few of your cards on your phone only - nothing is sent anywhere, and signing out clears it. Something broken, or something missing? Write to support@ai4life.cloud - a real person reads it.
