Welcome to pinál — a free vocabulary management system that is designed with a pin algorithm under the hood.
It brings the idea of having one large vocabulary for all your words with one type of test powered by a special algorithm, whose job is to only to ask you the words that matter. You can create an unlimited number of vocabularies with unlimited number of words. All languages of ISO 639-1 are supported.

vocabulary

- All the words known and used by a particular person.
- All the words that exist in a particular language or subject.
Every week our Spanish teacher gives us a list of vocabulary to learn.
The character of children's vocabularies cannot be predicted solely on the basis of the words they hear and the concepts they possess.
The interface of the service is very minimalistic. You can only create a new vocabulary, add some words there and take some tests. You can not move words inside the vocabulary. In fact, you can’t do anything with it except of making adjustments to some incorrectly added word. You may be asking yourself now: “If there is so little functionality, why is it called vocabulary management system?” Well… that’s the point. There is a management going on, but it’s being done by the pin algorithm. This algorithm knows what words are recently added, what are very well known and what are quite hard to learn, so when you take a test, it knows what to ask. Basically, what it does is places the words in two-dimensional space and uses logarithmic and trigonometric functions to alter a pseudorandom above that space. It’s called “pin algorithm” because when you remove a supplementary dimension and leave only the main axis it will resemble a pin. That’s where the term “matured words” comes from. These are the words that have entered the pin algorithm loop and therefore have a different behavior now.
The project was created for personal use, family and friends. But if you are curious about it, you may try it out. You should understand however its main idea — one big vocabulary for a particular language that is being updated throughout years of studying. One algorithm that is responsible for it and one test that you periodically take to refresh your knowledge. Yes, you are not restricted with the number of vocabularies, and you can name them as you want. So it is possible to create a set of dictionaries on different topics like fashion, health, math or computer science. But it doesn’t really matter to what category some word belongs. You just have to learn it and be able to occasionally stumble upon it while doing another “random 100” test. And that was the reason why to design the pin algorithm at all.
Anyway, you may also consider another service like Anki, Quizlet, Memrise and so on. They all implement their own algorithms that may suit your learning style better.
