Flash cards are house-drawn picture cards for vocabulary: one text-free picture per meaning, so nothing on the card gives the word away. You pick a language and the topics you want, start the test, and type the word for each picture. Every answer is checked at once, and the card then shows the word, its accepted forms and a short explanation.The test is the whole flow: there is no separate browsing deck. What you choose before you start decides which cards you get.
Open Flash cards from the sidebar. The setup screen shows the language you are learning, the language the explanations are written in, and the topic tiles (Family, Fruits, Town and transport and so on) with the number of cards each one holds. Tap tiles to combine topics, or leave them all off for every A1 card. The line under Start the test tells you how many cards the test will have.On a phone the setup panel opens collapsed with a one-line summary of your selection. Tap it to change anything.
The test
One card at a time: the picture, the instruction and, when the card has one, a short clue sentence in the language you are learning. Type the word and press Enter or Check answer. Hint shows a clue sentence in the language you are learning when the card has one, then the first letter, then the number of letters. Skip moves on without an answer.A right answer says Correct. A wrong one says Not quite. and shows the correct answer with its explanation underneath. Next card takes the focus, so Enter continues. Typing a broader word, the family name of a fruit instead of the fruit, is not marked flatly wrong: the card says so ("Yes, "Obst" is the general word. Now name this particular one.") and gives you one more try before it reveals its answer. A one-letter slip gets the correct spelling, and a form the card did not ask for, a plural under a singular instruction, is named as such.The header shows where you are and offers Quit; Escape does the same. At the end the summary gives your score and lists the words you missed or skipped with their meaning. Test the missed words runs a test of exactly those, Test again repeats the whole selection, Change selection goes back to the setup.
More than one right answer
A card built for one word usually accepts more than one answer: a spelling variant, a regional synonym, the plural where the language forms it regularly, or the word with its article where the instruction says so. The printed correct answer shows the word itself and its reviewed equivalents, not every form the checker would accept.
Best practices
Pick two or three topics rather than everything: a test of forty cards is long, and a short one you finish teaches more than a long one you quit.
Read the explanation after a miss before pressing Next card. The word you got wrong is the one worth a second look.
When the retry line asks for a more specific word, answer with that word straight away rather than retyping the broad one.
Under the hood
Flash cards are a Premium area end to end: the setup, the test and the pictures all sit behind the same check, so a shared picture link never leaks to a signed-out or free reader.Every picture is AI-generated and carries the required marking; the underlying sheet goes through the same safety review every generated image on the site does before any tile is served.Pictures are served from a content-addressed URL that your browser caches for a year, so a card you have seen once loads instantly the next time.
