Learn vocabulary as a map, not a list. Master words with smart daily review — and collect a unique card for every word you learn. Start your first map today!
Most vocabulary apps hand you a list of words and hope something sticks.
Seed works differently.
Seed builds your vocabulary the way your brain actually learns — through connected topics, visual maps, and daily practice that keeps bringing you back. And now, every word you master becomes a collectible card. Whether you're a complete beginner or expanding beyond the basics, Seed grows with you.
YOUR VOCABULARY AS A MAP, NOT A LIST
Pick a topic — Food, Travel, Work, Technology — and Seed's AI generates a personal vocabulary map for you. Words connect to other words. Topics branch into subtopics. Every node you unlock is a word learned, not just a word seen.
As your map fills in, you can see exactly how far you've come. As you forget, Seed notices — and brings those words back at exactly the right moment.
NEW: COLLECT EVERY WORD YOU LEARN
Every word you master drops as a card — and no two collections are alike. Rarity is rolled personally for you, so your "serendipity" might be Legendary while your friend's is Common. Every card comes with its own background design, and every card carries a discovery number — learn a word before anyone else in the world and your card is marked #1 forever.
Word cards in 5 rarities — your roll is yours alone
Discovery numbers: be the first to learn a word and claim #1
Unique card backgrounds for every word
A chest after every lesson + bonus chests full of rewards
Upgrade cards with shards to higher rarities
Collection milestones with rewards
Your collection isn't decoration — it's your vocabulary, made visible. And it's one of a kind.
PRACTICE THAT DOESN'T GET BORING
Seed offers multiple practice modes so every session feels different:
Flashcard review
Multiple choice
Matching pairs
Listening practice
Speaking practice
Sentence practice
Story of the Day
Every mode reinforces the same vocabulary from a different angle. That's how words move from short-term memory to long-term recall.
SMART SPACED REPETITION
Seed's review system tracks every word you've learned and schedules reviews based on how well you know them. Weak words come back often. Strong words fade into the background until you actually need a refresher. Your practice time goes exactly where it matters.
DAILY GOALS, QUESTS & REWARDS
Set a daily goal and let Seed keep you accountable. Complete daily quests, earn XP, level up, and collect gems to spend in the shop.
Power-ups like Streak Freeze, Double XP Boost, Map's Compass, and Repair Potion make learning feel like a game — because the best habits are the ones you actually enjoy.
SHOW OFF YOUR PROGRESS
Customize your profile wall, showcase your rarest cards, add friends, and compare your weekly XP. Learning sticks better when someone's watching.
STREAKS & PROGRESS TRACKING
Build a daily practice streak and watch your vocabulary grow alongside it. Miss a day? Streak Freeze has you covered. Check your streak calendar, word stats, and review history to see your progress in full.
WHO IS SEED FOR?
Beginners starting their first language learning journey
Intermediate learners who want to expand their vocabulary fast
Anyone who finds flashcard apps repetitive or boring
Learners who want short, focused daily practice sessions
People who learn better visually, through maps and connections
Collectors who want their progress to feel like a reward
WHY SEED IS DIFFERENT
Most vocabulary builders give you lists. Seed gives you maps — and a collection to prove it.
Instead of memorizing isolated words, you build a living network of vocabulary — organized by topic, connected by meaning, strengthened by AI-powered review, and collected card by card. It's not about grinding through flashcards. It's about building vocabulary you'll actually remember and use.
