Flashcards are good at getting a word into your head and bad at getting it out of your mouth. StudySes’s vocabulary builder uses flashcards for the first job and puts them next to the thing that does the second: an AI conversation partner you can use the word with the same day, with feedback on what you said. Review the card, say the word in a sentence to someone who answers, read the feedback, and the word is yours in a way a word list never manages.

How it works
You open the vocabulary builder, work through a set of flashcards from the built-in word bank, and review them in short sessions until the meaning comes without effort. Each card is a quick recall test: see the prompt, produce the word or the meaning, check. That is active recall, which is why flashcards work better than re-reading a list, and why five minutes of cards on a bus is worth doing.
The step most flashcard apps leave to you is built in here. Once a set of words is familiar, you take them into a role-play or an open conversation and use them. The AI partner replies to what you said, and the feedback afterwards shows whether the word was used naturally, in the right form, in the right place. A word that passes that test is one you will produce in a real conversation; a word that only passes the flashcard is one you will understand when you hear it, which is a different and smaller thing.
Progress analytics keep track of how often you practise. We describe the review as review, not spaced repetition, because the store listing does not make that claim and this site only says what the listing and the app confirm.
What it is for
The vocabulary builder is for learners whose problem is not knowing words but reaching them. Most intermediate learners understand far more words than they ever say; in a conversation the familiar words come out and the newer, more precise ones stay on the shelf. Flashcards plus conversation move words from the shelf to the hand.
It fits three uses in particular:
- Preparing for a specific situation. Before an interview, a trip or an appointment, review the words that situation needs and then play the matching role-play, so the vocabulary and the scene are rehearsed together. The spoken English course lessons give the grammar the words sit inside.
- Reading or listening above your level. The words you keep meeting in articles or podcasts are the ones to prioritise in your review and then take into a conversation, instead of looking them up and forgetting them.
- Keeping a second or third language alive. Ten minutes of review and a five-minute chat with the AI partner in German or Italian is enough to stop a language you are not currently studying from fading.
Our guide on how to practise speaking a language alone shows where a flashcard session fits in a weekly plan.
What it does not do
Flashcards do not teach you to speak, and StudySes does not pretend they do; they are the feed for the speaking features, not a substitute. The vocabulary builder does not score your pronunciation of the words, so use the audio pronunciation guide to hear them and your own ear to check. And we do not claim a spaced-repetition algorithm: the cards are there to review on a schedule you keep, and the honest measure of whether a word is learned is the conversation, not the card count.
Flashcards alone vs flashcards with conversation
| Word list | Flashcards alone | Flashcards + AI conversation (StudySes) | |
|---|---|---|---|
| Active recall | No | Yes | Yes |
| Tests recognition | Partly | Yes | Yes |
| Tests production in a sentence | No | No | Yes |
| Feedback on how you used the word | No | No | Yes, after each exchange |
| Fits a five-minute gap | Yes | Yes | Cards yes; conversation needs about ten minutes |
| Needs a connection | No | Depends on the app | Downloaded course materials work offline; the conversation needs one |
The first two columns build recognition, which is necessary and not sufficient. The third adds the step that makes a word usable, and the feedback that tells you whether it was. If you already use another flashcard tool and like it, keep it; the point of this page is the second step, and StudySes’s AI partner will take words from anywhere.
Getting the most from it
Keep the daily number small and the follow-through strict: five to ten words, reviewed the next day, each used in at least one conversation within the week. Learn words in phrases rather than alone, because the phrase is what you will actually say. When the feedback marks a word as misused, that word goes back to the front of your review, and into the next conversation on purpose. Over a month this produces a smaller vocabulary than a word-list binge and a far larger spoken one.
Download StudySes for free, review one set of cards, and then open a conversation on the same topic before the day ends.

Frequently asked questions
Do flashcards actually work for learning vocabulary?
Yes, for the first stage: flashcards use active recall, which beats re-reading a word list for getting a word into memory. Where they fall short is the last stage, producing the word in a real sentence under time pressure. StudySes puts flashcards next to an AI conversation partner so the word you reviewed this morning gets said this evening.
How many new words should I learn a day?
Five to ten new words a day, reviewed the next day and used in a conversation within the week, is sustainable for most learners. Twenty or more a day usually collapses into a review backlog nobody clears. A smaller number you actually say beats a larger number you only recognise, which is why StudySes pairs the flashcards with speaking practice.
Does StudySes use spaced repetition?
StudySes has a vocabulary builder with flashcards that you review in short sessions; the store listing does not describe a spaced-repetition algorithm, so this site does not claim one. What matters more than the schedule is the next step: use the words with the AI conversation partner, where feedback on your answer shows whether the word was used correctly.
What is the best way to memorise vocabulary for speaking?
Learn the word in a phrase, review it the next day, then say it in a conversation within the week. Recognition comes from the flashcard; production comes from using the word while someone is listening and responding. In StudySes that someone is the AI conversation partner, which replies and then gives feedback on what you said.
Can I use the flashcards together with the role-plays?
Yes, and it is the best way to use them. Review a set of words from the vocabulary builder, then open a role-play on the same kind of situation and use those words while the AI partner plays the other person. The feedback at the end shows which words you used naturally and which still need work, so the next review session has a purpose.
