Your English is broken.
This is how you fix it.

An English learning app for A2–C1 learners. Build your vocabulary, practise speaking and remember the English you need.

01

You don't know enough words.

Choose words from your own life, or try suggested words selected with your CEFR level in mind. The suggestions are optional. You decide what is useful to learn.

You don't know enough words.

Build a bigger vocabulary from two directions.

Bring words from your own life, interests and situations. Want some ideas? Ask for four suggested words from the list, selected with your CEFR level in mind. Learn them if they are useful to you, or stick with your own choices.

  • Build from your own vocabulary
  • 4 suggested words, if you want them
  • My36 practice
02

You can't use the words you know.

You can't become fluent by just knowing a word. You need to know the common phrases and collocations that use it. WordCat gives you the other essential pieces to truly understand how the word works in real English.

You can't use the words you know.

Knowing a word is not the same as knowing how to use it.

In My Words Climb, start with a word, learn its word partners, then build up to a useful phrase and a sentence pattern. Learn how the pieces fit together, so you can use the word instead of just recognising its translation.

  • Collocations
  • Lexical chunks
  • Phrase practice
  • Sentence practice
03

You learn words. Then you forget them.

Memory cards are great, but not enough. The quiz is like a friend who tests you. It brings old words back before you forget them. These are your words, and you're being quizzed on them.

You learn words. Then you forget them.

Flashcards can show you a word. WordCat makes you try to remember it.

The Quiz works more like a testing partner, checking what you can recall and bringing older language back when you need more practice.

  • Active recall quizzes
  • Memory review
  • Vocabulary testing
  • Practice
04

You avoid speaking English.

Practise with an AI speaking partner before you talk to a real person. Use your own words. Then see what was good and what to fix.

You avoid speaking English.

You need somewhere safe to practise before a real conversation.

WordCat gives you AI speaking partners, lets you build answers using your vocabulary and gives you feedback on what you actually say. Save conversations and corrections.

  • Speaking practice
  • Pronunciation feedback
  • Grammar feedback
  • Situations
05

English feels boring. So you stop.

Learn with more than 1,200 songs. Listen to real English, see how it works, and keep going on the days when a book is too boring.

English feels boring. So you stop.

Learning is easier to continue when the content itself is interesting.

You keep starting again.

Your Diary keeps the work you choose to save. Revisit a conversation, a correction or an idea, and start from where you stopped.

You keep starting again.

Taking a break should not mean starting from zero.

Save useful work in your Diary and return to it when you need it. Your saved vocabulary and practice give you something to build on after a break.

Sentence Builder

You understand the rule but say the same simple sentence. Get one key upgrade, then use it yourself. Extend the sentence and extend your fluency.

Mini Course

A meeting on Friday? A short course with the key phrases for that one situation. The phrases are lexical chunks — the kinds of phrases native speakers learn. Each one has a purpose.

Situation Trainer

The interview starts and you're not ready. Rehearse interviews, apologies, complaints and ordering first. Bring in content from your Mini Course.

Chat with Lily

Nobody to practise with? Talk with Lily. She corrects gently, keeps the chat going and explains in your language. You get gentle corrections and phrases native speakers use all the time.

Writing Tutor

People understand you but never correct you, so you repeat the same mistakes. Bring your own email. Get it corrected line by line, in your language. Identify the mistakes that make you look like a beginner.

Writing Tasks

Read the lesson but never use it? Get writing prompts on each passage's teaching point, corrected line by line. Productive output is really important.

Sophia Chat

You hide in the same safe sentences. Sophia asks hard questions and won't accept one-word answers. Conversation with real pressure. Sometimes you need to be pushed to learn more.

Chunk Finder

Reading word by word? Paste real English and see the reusable phrases inside it. This is how native speakers learn: they find chunks of language with a single purpose. It makes fluency easier.

Courses

You know words and grammar but still get stuck in conversation. Functional-phrase courses from A2.1 to C1: 50 days, two useful frames each day, with AI feedback.

Rephrase

Correct, but wrong for your boss? See your sentence five ways, from friend to boardroom. Real fluency means knowing how to say the same thing in different ways. This is the difference between intermediate and advanced speakers.

Vocabulary Builder

Not enough words to say what you mean? Type a sentence or add a photo, then pick four words. WordCat builds the card from your life and your needs. Don't just learn from word lists.

Practice Friend

You thought you knew the memory card but still can't find the word when asked. Get a quiz on your 36 words, like a friend who practises with you. Explore even more about each word inside the quiz.

Tutor

Don't know what to work on next? Your Tutor knows your goal, your words and your mistakes. Ask it, and it can even plan a weekly set of things for you to study.

Debate

Small talk is easy. Making a point is not. Pick a side, argue with an AI and build counter-arguments. Test your English and get the phrases and chunks you need to become better at debating.

Memory

You learn words, then forget them. Our Anki-style card system brings back the words you're about to forget, then builds on this with quizzes.

Shadowing

You can read it but can't say it without the text. Listen, fill the gaps and say it from memory. Improve your speaking by listening and speaking at the same time as the speaker. Slow everything down or make practice harder by showing only a few words.

Story Writers

You never write anything of your own. Write a story with Alex: drama, science fiction or fantasy. Build the plot, learn new words and get corrected. A creative, fun way to explore ideas and build your imagination.

Custom Pack

Useful phrases get lost between sessions. Keep them in a pack: travel, work, exams or slang. Add audio and quiz them too. Create a Custom Pack for verbs, adjectives or any phrases you want to remember.

Songs

Grammar from a book is boring and doesn't stick. 1,200 songs at your level, each teaching one thing. Comprehensible input as it is meant to be.

Chunk Coach

You know the word but stop mid-sentence. A chatbot asks what goes with your 36 words. Build the phrase yourself, then check it. Thinking in English means thinking in chunks, not individual words. This is the real key to fluency.

Shy Chat

You wait to feel confident before you speak. Yuki listens more than she talks. You lead, she follows. Find your voice. Not everyone speaks English in the same way.

My 36

A long word list is not progress. Nine cards, 36 words with their partners. Small enough to really learn. Add four words and the oldest four move to long-term Memory. Then climb through each card from word to phrase, making sure you understand the word's real meaning and use.

Explainer

Too hard to read? Use Explain on any song or passage, and WordCat gives you a detailed explanation in your language of why the English works this way. Every difficult phrase is explained in your language.

Pronunciation

Do people ask you to repeat yourself? Listen to a native speaker say the sentence, then record it yourself and compare. Submit your audio to see which words were unclear. WordCat gives you a score and recommends what to practise.

Chunks

You know the word, not its phrases. Build real phrases from any word. Fluency depends on speaking and writing in chunks, or groups of words. If you try to remember the word and grammar separately, mistakes become more likely and English becomes too slow and difficult.

Life Coach

You can't talk about real problems in English. Zara coaches you through work, relationships and decisions. Sometimes you need to extend your English into personal situations.

Speak the Target

Understand the lesson but never say it? Guided speaking on each passage's teaching point. Speak what you're learning and get feedback.

Deep Translate

You know every word but miss the meaning. Paste the idiom, guess first, then get the meaning in your language.

Finish the Story

You never write your own English. A story built from your own 36 words stops at a cliffhanger. You write what happens next, your mistakes are corrected, and the story continues. A creative way to use your newly learned vocabulary.

Diary

With other apps, your corrections disappear and useful phrases get lost. With WordCat, everything you write, say and save is kept by date. Come back at any time to see all your work and progress.

The Duolingo Trap

You've tried the fun apps and the boring apps, but most tools keep you passive:

Duolingo

Duolingo

Fun, but you just tap buttons and repeat fixed phrases. Learners can practise for years without becoming fluent. Good for beginners.

Video Courses

Video Courses

You buy them with good intentions, but quit because 'watching' isn't 'doing'. No feedback means no fluency. Sometimes you don't have the time. It's boring.

Anki

Anki

Powerful, but you collect thousands of cards you never see again. You download a 3,000-word list and then hope you remember it.

Netflix

Netflix

Enjoyable, but too fast and too dense to learn from. You're still having fun, so it isn't all bad.

Tutors

Tutors

$30/hour is expensive to maintain long-term. Do you really need a tutor these days? Perhaps, but maybe only occasionally.

You don't need another app. You need a system that is personal to you, shaped around your life and fun to use. WordCat adapts to your energy, not the other way around.

Three Gears. One System.

Stop feeling guilty when you're tired. Switch gears instead. We combined active training with passive immersion so you never break the loop.

Frequently Asked Questions

Is WordCat right for beginners?
WordCat is designed for elementary to advanced learners (A2 to C1). If you're a true beginner with zero English, take the free CEFR placement test first — and consider starting with a more basic app until simple sentences feel comfortable. We recommend Duolingo for absolute beginners.
How does the My 36 system work?
My 36 focuses on up to 36 words from your 9 newest sentence cards, with 4 words per card. In My Words Climb, build from each word to its word partners, a useful phrase and a sentence pattern. Older cards move into Memory as you add new ones. Review what is due before building further.
What happens to my old vocabulary?
When an older card leaves My 36, it moves into Memory for spaced reviews. Try recalling the English, then choose Hard, OK or Easy to describe how difficult it felt. That rating helps plan the next review; it is not a correctness grade.
Can I practise speaking?
Yes. Pronunciation Practice records you and gives word-by-word feedback. Every song and passage has speech-to-text practice. The Situation Trainer lets you speak through any real-life scenario. And the chat characters in Academy all support audio in and out.
How does the free trial work?
You get 7 days of full access — no credit card required. Try the tools, build vocabulary cards and see if the system fits you. The usual vocabulary-building and review limits still apply.
Can I cancel anytime?
Monthly plans can be cancelled anytime. Annual plans come with a 14-day money-back guarantee.
What devices does WordCat work on?
WordCat is a web app that works on modern browsers — phone, tablet, and computer.
How is this different from Duolingo?
Duolingo is great for starting. WordCat is for when you're ready to move past fixed exercises and start creating your own English — from your own sentences, photos, and topics.
Can I use WordCat for IELTS or TOEIC prep?
Yes. When creating cards, you can choose Everyday, IELTS, or TOEIC focus — the vocabulary shifts to match. The Academy and Course catalogue include exam-focused content.
How much time do I need per day?
Around 20–30 minutes of focused WordCat practice beats hours of passive watching. On busy days, the Feed gives you 5-minute micro-sessions.
How much content is included?
Over 3K exercises, including 1,200 songs and 1,500 audio passages, across CEFR levels A1 to C1; a 250-lesson free fluency course with more courses arriving; and vocabulary building from your own sentences and photos.
Do I need a teacher?
You can absolutely learn independently with WordCat. If you also work with a teacher, they can help you build content that feeds back into the system.
