Quick answers to the things most learners want to know before signing up.
Does writing sentences help you learn English vocabulary faster?
Yes — it is one of the most evidence-backed techniques in vocabulary research. Producing a sentence with a new word forces "active recall" plus "generative use", which together build a stronger memory trace than simply reading or recognising the word. Tilingu uses this exact method: every new word can be practised by writing your own sentence, and the AI checks your grammar and usage in real time so you learn what works and what doesn't.
What is the best AI app to learn English vocabulary?
A great vocabulary app needs three things: (1) a proven memory engine — Tilingu uses SM-2 spaced repetition, (2) active practice rather than passive flipping — Tilingu generates writing prompts, fill-in-the-blank questions and exam-style reading passages from your own word list, and (3) AI feedback so you know whether you are actually using each word correctly. Tilingu combines all three in a single free tool.
How can I memorize IELTS vocabulary effectively?
The fastest path to IELTS Band 7+ vocabulary is to learn the IELTS Academic Word List with spaced repetition and then immediately practise using each word in a Writing Task 2-style sentence. Tilingu's IELTS pack does both: SM-2 spaced repetition keeps the words alive, the AI writing-feedback mode forces you to produce them, and the AI-generated reading passages mirror the format of the real Reading test.
What is the best way to learn TOEFL vocabulary?
TOEFL rewards depth over breadth — knowing a smaller set of high-frequency academic words well beats memorising long generic lists. Tilingu's TOEFL pack is built on that high-frequency pool, and every word can be drilled with AI-generated iBT-style reading passages and writing prompts so you encounter the vocabulary in the same context it appears on test day.
