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.

This page has a child: Language/Multiple-languages/Culture/Internet-resources-for-learning-specific-languages.

-- 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” in 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. If you see there are multiple links in “Releases”, select the link with your corresponding operating system, CPU architecture and other clues in its filename. “md5”, “sha256”, “sha512”, etc. are checksum formats, which can be used to check the integrity of the downloaded file.

If you see SourceForge, you may simply click on the “Download” button. In some cases, the downloaded file is not what you want. Then you need to find it out in “Files”.

To run a program is written in JavaScript, there is a guide.

If a resource is using Electron.js, it means bloat, because Electron.js can be used to create cross-platform programs easily, but it means to integrate a Chromium in every program, which means bloat. What's more, it has been depending on Node.js, which has been having the background of political activism (Black Lives Matter). Political activism can cause unexpected damage, like node-ipc by RIAEvangelist on GitHub. Also, GitHub has the background of political activism (pro-Ukraine).

See if the program is updated recently. If a program is using Java and is using Apache Log4j 2 and has not been updated since 2021.12.09, then anyone should avoid it.

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

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

Tips[edit | edit source]

Some programs need to use the command line. There is an article about how to do it on Windows.

Resource Selection Criteria[edit | edit source]

To be listed on this page, resources should possess at least one of the following characteristics:

  1. be rich in FREE content (not just a trial or not fulfilling the need in the free part), and the free content is mostly accurate, and the free content is not all covered by other free ones;
  2. be made with a unique, good idea;
  3. has no better alternatives.

Resources possessing the following characteristics will be given disadvantage:

  1. propagate specific political or religious ideas without possibility of discussion.

Resources with the following features will be given a little priority:

  1. available offline;
  2. available on multiple platforms;
  3. multilingual user interface;
  4. lightweight (including “written in C”);
  5. open source;
  6. privacy-friendly (including “registration not required”).

[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 on Linux, but it requires 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

It is lightweight and supports many languages, with many keyboard layouts. But it has problems, such as poor Japanese support.

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”.

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.

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

Good open-source browser add-ons for Chromium or Chrome include:

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 a solution. Expect that Bazel it utilises to cause troubles.

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.
