Hello polyglots, 😀


The Internet is a giant treasure. It provides so many free services.

On this page we have listed the sites that offer the most useful services for polyglots.

Introduction[edit | edit source]

Advices[edit | edit source]

This page is updated from time to time, not frequently, not regularly. “But how do I know what you have changed since the last time I come here?” Try this: hover your mouse over “Actions” on the upper right corner of this page, click on “history”, select the current and the version you saw last time, click on “Compare selected versions”.

It would be great if you pay a visit to every site on the list. Don't lose your curiosity.

If you want to do creative work to help others to learn languages and to know about cultures, please visit Language/Multiple-languages/Culture/Productivity-tools-for-polyglots.

If you see GitHub or GitLab links, please notice that the download icons mean to download the source code. Unless its language is interpreted like Python and Perl, you will need to build the program on your own. Links to download binaries (built programs) are elsewhere like “Releases” or links in the README.MD file.

It is not recommended to put some banner like “featured in Polyglot Club” on your website, because this list is dynamic.

It is highly recommend to have privacy protections on. An open-source website on privacy: https://privacyguides.org/

[edit | edit source]

!! https://colemak.com/

This one supports a lot of languages in Latin script, but it means to learn typing again. It is worth it. You may have noticed that “Kolemak” is even better than Colemak. How to modify keyboards will be discussed below.

A better layout image.

Note that the download link on the home page is “Caps Lock Unchanged”. The idea of replacing Caps Lock with Backspace is great because of its convenience to press Backspace, but having it unchanged is generally better because it's punitive to press Backspace, urging you to make fewer misspellings.

There is a flaw of no “„” or “‚”. You can replace “÷” and “×” with them. Also, the positions of single and double quotation marks only benefit British people for not pressing Shift. You can exchange their positions, too.

If you want to type even more characters, you will need the autocorrection, which can turn multiple characters into one.

There is a modified version and local variants.

https://bepo.fr/wiki/Accueil

Based on French, giving consideration to European languages. But if you don't type French much, it might be not ideal.

No English translation for this site, but it doesn't matter, because this keyboard is generally pre-installed in common operating systems. You just need to find it in the “French” section of keyboard settings.

https://forum.colemak.com/topic/519-rulemak-russian-colemak-layout/

Variant of Colemak for typing Cyrillic. It is available as source code. It is pre-installed in Linux, but it require some effort as mentioned in the “Colemak” section to make sure it appears in the files. “Greek (Colemak)” is also available.

For Windows, Portable Keyboard Layout is required. Or you can use that keyboard creator to do it manually.

!! https://play.google.com/store/apps/details?id=kl.ime.oh

Book under a public license. Old and short.

https://www.logicmatters.net/tyl/

All rights reserved, conditioned distribution allowed.

[edit | edit source]

!!!! https://www.duolingo.com/

The best free online language courses. It is actually a collection of exercises instead of real teaching courses. It is also under criticism, from quality to method.

Don't neglect their other products, especially Push.

https://www.coerll.utexas.edu/coerll/materials

This one has a lot of materials as well as other things.

https://fsi-languages.yojik.eu/

Mainly courses of Foreign Service Institute, Defense Language Institute, Peace-Corps. FSI is initially aimed at middle-aged officials, so maybe not everyone likes it.

https://www.coursera.org/browse/language-learning/

Some super cool courses. This is suggested by RomDasha.

!!!! https://www.lingolia.com/

A little site with useful basic courses of 5 languages with good design.

https://en.wikibooks.org/wiki/Subject:Languages

Books are mostly incomplete and in lack of update, but some are nearly completed or completed, not bad.

https://librelingo.app/

An experimental language-learning platform by community. Still far from being mature and is active. It is open-source.

Speaking
[edit | edit source]

!!!! https://forvo.com/

Dictionary of pronunciation.

!! https://speechling.com/

Submit the recording and wait for the response. Supported languages are not many.

https://www.fon.hum.uva.nl/praat/

With this one, you can say you are “studying” pronunciation.

A little tutorial and a big playlist of various videos.

!! https://ivypanda.com/tongue-twisters

Try not to hurt yourself when practicing.

It covers an older site and has improved a lot. There's no copyright affair involved because such a list is not a “creative work”.

You may want to ask if this page is protected by copyright. All my comments are protected, the list of links like the one in that brief version is not.

Vocabulary
[edit | edit source]

!!!! https://apps.ankiweb.net/

Offline flashcard platform. You can find its manual at “Docs” on the website. Content can be rendered in HTML and CSS. There are also many powerful add-ons for it. It is open-source.

Its community has many shared decks, but this is not mentioned at the home page. There is a successful collaborative project: Ultimate Geography.

Unfortunately, not free on iOS.

Related add-on wiki page. Some are picked out by me.

You can set up your own server for synchronization with djankiserv or anki-sync-server; learn with new tabs in Chromium or Chrome; make it a slideshow.

If you want to batch rename files, there is a program to do it and it is open-source.

If you are still confused, go to communities about Anki and find solution.

!! https://github.com/tema6120/ForgetMeNot

Flashcard program for Android. More advanced than AnkiDroid in many aspects, including necessary instructions. You can even set intervals for the spaced repetition. It is open-source.

!! https://mnemosyne-proj.org/

If your want a simple alternative to Anki, try this one. It is open-source.

!!!! https://www.memrise.com/

Flashcards in high quality can be found. Some most popular languages have courses of 0-5k and 5k-8k words, or divided differently and still reach 8k. A few can be over 30k.

To see the flashcards without registration, go here.

Though it is said to be memorizing words with “mems” (memes in many cases), the “mems” are actually not in good quality.

You can import from a spreadsheet.

!! https://quizlet.com/

It is not so good at efficient memorization as Memrise. It is for having quizzes. But you can find specific practice such as reflexive verbs, weak nouns.

It even encourages you to copy other people's card decks and create your own variants, in case a good deck has flaws and the creator doesn't respond to it.

You can import from a spreadsheet.

!!!! https://www.clozemaster.com/

Learn with cloze. It is effective, but sometimes it is just repeating the same point in different questions. Also, synonyms are not supported.

!!!! https://context.reverso.net/translation/

Among its products, the mobile version of Context seems to be the most helpful: learn and practise new words with example sentences.

!!!! https://babadum.com/

It's pretty good for educating young polyglots.

!!!! https://github.com/tkrajina/10000sentences

Sentences from Tatoeba to practice. It is aesthetically same with Anki (I mean copy-paste). It is open-source.

!! https://www.languageguide.org/

Some basic vocabulary.

!! https://babadada.com/

Visual dictionary. No grammatical genders or pronunciation, suitable for reviewing.

A lot of languages has not been completed yet, without any notice. Also, look out for polyseme mistakes.

https://github.com/lexica/lexica

Game of finding words on Android. It is open-source.

https://en.wiktionary.org/wiki/Appendix:Swadesh_lists

Swadesh lists are basic vocabulary initially for linguistic use. But it can be the starting point of vocabulary building for language learners as well.

!! https://en.wiktionary.org/wiki/Wiktionary:Frequency_lists

Frequency lists. Make use of it with programs that help to memorise, such as Anki.

If you seriously want to learn a language, and there are no ready-made free flashcards reaching the native level, and you don't want to spend money, this may be the most effective way to memorise words.

Test
[edit | edit source]

https://lingua.com/

A few materials for beginners. Better treat it as your proficiency tests instead of learning materials because it's not much.

!! https://www.transparent.com/language-resources/tests.html

Test your proficiency.

There is only one set of test for each language. Don't search the meanings of the words you don't know, if you want to take this test again later.

!! https://www.arealme.com/vocabulary-size-test/en/

For testing your vocabulary size.

There is only one set of test for each language. Don't search the meanings of the words you don't know, if you want to take this test again later.

!! https://www.ezglot.com/vocabulary-test.php

Test your vocabulary size. It's faster and maybe not so accurate. The result is at an inconspicuous corner.

For Chinese, Japanese, Lao, Thai, Vietnamese and some other languages, word segmentation is required.

You can also modify the source code (don't execute the file, but open it with a file editor), like these:

  • $font: font name and size.
  • $span_black_open: colors of black characters.
  • $span_red_open: colors of red characters.

p.s. Colors are “web colors”. You can find a “color picker” to get the hex values of a color.

  • $wpm = 200: default reading speed (words per minute).
  • button_slower: WPM increment per click.
  • button_faster: WPM decrement per click.

Maybe when I have free time, I can try converting it into Python and do some modification: add shortcuts, create a user interface with BeeWare, add word segmentation support.

Save the web page as a single file.

There is also a SingleFileZ, which can compress pages.

https://learning-with-texts.sourceforge.io/

This is a PHP project. The page design is very bad and you need sufficient patience to read the guide and follow it. It's a DIY, offline and free version of LingQ. Inflection is not supported. It is open-source.

LingQ is freemium, but it can't be recommended for its unacceptable limitations on free users.

A video for its introduction; a video about its setup; a video about its more features.

Their discussion is open again now. Hope they can get on well with each other.

I have a question: Why not Python?

Writing

Search before you ask.

Do not feed the trolls.

Do not answer blanked homework questions, because the questioner is too lazy to deserve an answer.

Do not answer the meaning of a single word. The questioners should consult a dictionary on their own. Exceptions are newbies, because they may be just following the tutorial and have a try, not lazy.

Do not ask questions in English channels, because the questions are too many, the answer rate is extremely low. Try asking at Polyglot Club.

Ask in parallel text. Then the respondent won't need to ask you about the real meaning if the sentence is not understood.
