Decades of cognitive science meets premium botanical design.
Every design decision in Seedling traces back to decades of cognitive science research — and wraps it in the most beautiful learning environment ever created.
Our modified SM-2 algorithm schedules every word for review at the precise moment before you'd forget it, turning short-term glimpses into permanent long-term memories.
Four unique quiz types — from root-matching to drag-and-drop — keep your brain actively retrieving words, not passively recognizing them.
Every word you master becomes a plant in your personal garden — visually growing from seedling to ancient oak as your mastery deepens.
Choose from curated thematic courses — Travel, Business, Medical — or build your custom vocabulary garden from any domain you care about.
Choose a language and topic. Seedling plants 3 foundation words for new learners — your starter garden. Each word is presented with pronunciation, definition, and an example sentence.
Return each day for a 5-minute session. The engine serves exactly the right words at the right time — mixing SRS reviews with one fresh new word to keep growth sustainable.
Words evolve through 5 mastery levels: Seedling → Sprout → Sapling → Tree → Ancient Oak. Each level requires deeper recall challenges. Real knowledge, earned naturally.
Export vocabulary sets, challenge friends in live duels, and showcase your growing Garden to the world. Your garden is your proof of mastery.
