LetsWords (letswords.com) is an online English trainer where you don’t just memorise words, you use them. You write a sentence with the word you’re learning, and LetsWords shows the mistake, the correction and a more precise way to phrase it, with explanations in your native language: Russian, Korean or Vietnamese. It works for general English (work, emails, conversation) and for IELTS preparation, with Writing Task 1 and Task 2 practice in the same service. It runs in your browser and works by subscription, while more than 1,500 expression exercises are open for free.
What one LetsWords session looks like
Let’s walk through a session with the verb suggest. Almost everyone knows it, yet it often breaks down in a sentence.
1. The word in context. The card gives you the meaning, an English definition and examples: suggest means to put forward an idea or option for someone to consider. You can hide the translation and work from the English definition.
2. Using the word. You use suggest in a sentence about work:
My manager suggested me to take a day off before the release.
3. Feedback. LetsWords flags a mistake in the structure. After advise or ask you can say me to take, but not after suggest. The correct forms are suggested (that) I take or suggested taking. The explanation comes in your native language, and you can choose brief or detailed feedback. The corrected version:
My manager suggested that I take a day off before the release.
On top of the correction, LetsWords offers a version that gets your idea across more precisely:
Before the release, my manager suggested I take a day off to recharge.
4. Review. A few days later, the word comes back. You see its meaning in your native language, recall suggest yourself and write a new sentence with it. If the structure trips you up again, the feedback shows it before the mistake becomes a habit.
If you can’t think of a sentence, the generator suggests an idea in your native language at the difficulty you choose, and you put it into English. You’ll find more checks in How LetsWords checks English sentences: 12 real examples. The learning methods behind each step are explained on the LetsWords method page.

What LetsWords can do
Vocabulary practice
- Word card: meaning, definition, usage examples. You can switch the definitions to English and hide the translation, revealing it when you need it.
- Using the word: when you learn and review, you use the word in a sentence, for example about work or an exam topic.
- Feedback: usage and grammar mistakes, a correction, a better way to phrase it. Brief and detailed formats are available. The feedback takes your goal into account: an exam or general English.
- Idea generator: a sentence in your native language at the difficulty you choose, for you to put into English.
- Active recall: in review, you see the meaning in your native language, recall the English word on your own and use it again.
- Spaced repetition: words come back in later sessions based on your review history.
Sets and your own words
- Ready-made sets: Oxford 3000 and Oxford 2000 Advanced, IELTS and TOEFL sets by level, academic expressions, phrasal verbs, idioms and more.
- Your own words and collections: add vocabulary from work, reading and exam prep, and group it into personal sets.
- Editable cards: add to them and save examples that help you remember.
IELTS Writing
- Task bank: hundreds of Academic and General Training prompts for Task 1 and Task 2. Charts, tables, maps, processes, letters and the main essay types on a range of topics.
- Full answer: feedback against the four criteria: Task Achievement (Task 1) or Task Response (Task 2), Coherence and Cohesion, Lexical Resource, Grammatical Range and Accuracy.
- One-criterion exercise: practise one skill on a short passage instead of writing a whole essay every time.
- Help before you answer: a guide to the task format and a checklist before you submit.
- Feedback after you answer: comments are tied to your text, and mistake-fixing cards give you concrete actions for your next attempt.
Writing feedback comes without band scores: instead of a number, you see the strengths and weaknesses of your answer for each criterion and know what to rewrite. Learn more on the IELTS Writing checker page and in our guide to practising the four criteria.
One subscription unlocks everything: vocabulary practice and Writing.
How LetsWords differs from flashcards and a regular AI chat
From flashcards (Anki, Quizlet). Getting a “word / translation” card right doesn’t test whether you can use the word. In LetsWords, you recall it, use it in a sentence and get feedback on what you wrote. A mistake in a preposition, a collocation or a structure shows up during practice, not in the exam or a work email. See the full comparison in Anki vs Quizlet vs LetsWords.
From an AI chat (ChatGPT and similar). In a chat, you decide every time what to ask, which words to review and what criteria to check your answer against. In LetsWords, the practice is already built: word sets, a review schedule, feedback tailored to your goal, an IELTS task bank, one-criterion exercises, a format guide and a checklist. More in ChatGPT for IELTS Writing or LetsWords.
