Wordseed: Vocabulary Builder

5 words a day, remembered

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

You type the words you actually met — in a book, a meeting, a song. Wordseed brings each one back right before you'd forget it. Five a day is 1,800 words a year. 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 brings each one back right before you'd forget it. FIVE WORDS A DAY. THAT'S THE POINT. Wordseed caps new words at five a day on purpose. Add fifty tonight and in two weeks you'll open a 200-card queue and quit. Five a day is 1,800 words a year, because it's small enough to survive a busy Tuesday. 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. 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. Reminders work on the free plan too — an app that puts your reminder behind a subscription isn't teaching you anything. A NEW PASSAGE EVERY DAY Not sure which words to learn next? Today's Read gives you one short passage a day, with a handful of academic words in it. Tap any word you don't know and it becomes a card — met in a sentence, doing a job, the way you'd meet it in real life. ONE REMINDER A DAY, AT A TIME YOU PICK Wordseed knows which words are due, so the reminder says something real: "12 words are ready." One a day, never two — and if you review today, tonight's doesn't arrive. Pick the hour, or let the app use the time you usually review. FREE - Today's Read, the daily passage - 5 new words a day - All four exercise levels - 2 AI sentence checks and 1 AI suggestion a day - 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 - Unlimited AI sentence checks - Unlimited AI meaning and example suggestions - Synonym and spot-the-mistake drills, once a word is nearly yours - Bring an existing list over: import up to 200 words at once PRIVACY No ads. No tracking. No 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.

This one is about playing with your own words. NEW: WORD SPRINT A two-minute game made from the words you added yourself. First match each word to the meaning you wrote, then race 60 seconds to pick the right word - the clues get harder as you get them right. It never changes your review schedule, so play as often as you like, and your best score follows you to every device. Find it on Today when you have finished reviewing, at the top of Words, and in Stats once you have played. It needs four words you have already reviewed that are not due soon. YOUR STORY After a round, AI can turn the words you just played into a short, funny story - drag each word into its blank. Your first story is free. With Wordseed Pro, you get a new one every day. If a story ever feels wrong, tap Report this story. YOUR WORD LIST Every word now has a listen button, in the list and on the card. You can fix the spelling of a word without losing its review history. Long words no longer get cut off. MORE WORD IDEAS Not sure what to add? The word ideas panel now has 96 words in 16 groups, with new everyday ones: home and chores, health, shopping, friends and family. PRIVACY Our privacy policy now spells out what this version keeps: your Word Sprint rounds and stories, your time zone, and the kind of device you last used. We never sell it or use it for ads. Something broken, or something missing? Write to support@ai4life.cloud - a real person reads it.
