Blue Light Filter[edit | edit source]

!![edit | edit source]

Color temperature adjuster. It is open-source.

!![edit | edit source]

There are two highest-rated blue light filters. They have similar functions, but this one is chosen because it requires fewer permissions.

Rest Reminder[edit | edit source]

!![edit | edit source]

It can lock your keyboard and mouse buttons when it is time. It is open-source.

Self-Control Helper[edit | edit source]

!![edit | edit source]

Browser add-ons. It is open-source.

!![edit | edit source]

Prevent yourself from using your phone.

!![edit | edit source]

For Mac. It is open-source.

Keyboard[edit | edit source]

!![edit | edit source]

This one supports a lot of languages in Latin script, but it means to learn to type again. It is worth it.

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.

It is much easier to modify it to support Vietnamese on Linux because Linux allows typing multiple dead keys to modify a letter. It is suggested to set dead keys hỏi(hook above) to Shift+AltGr+H, móc/râu(horn) to Shift+AltGr+M or Shift+AltGr+R or both, nặng(lower dot) to Shift+AltGr+..

For languages with other letters such as Ə, Ɔ, autocorrection (or called in another way: text replacement) is required. AutoHotkey for Windows, AutoKey for Linux, Automator for macOS.

People think it's uncomfortable to type HE with it because you need to stretch your index finger and shrink your middle finger. I type E with my ring finger in this case.[edit | edit source]

This one is based on German keyboard, so you don't need to worry about lower quotation marks.

Its idea is 6 layers. But it may have trouble with your operating system. I suppose there could be 8 layers, among them 2 for Latin, 2 for Greek, 2 for Cyrillic, 2 for symbols.[edit | edit source]

Based on French, giving consideration to European languages.

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 “French” section in keyboard settings.

!![edit | edit source]

It is lightweight and supports many languages, with many keyboard layouts. But it has problems, too.

Typing[edit | edit source]

!![edit | edit source]

Open-source typing tutor.

!![edit | edit source]

A place to train typing.

Shortcuts[edit | edit source][edit | edit source]

Keyboard shortcuts. They make the life a little easier.

Notebook[edit | edit source]

!![edit | edit source]

It is open-source and privacy-focused. Can't insert images without payment.

!![edit | edit source]

It is open-source and privacy-focused. Can't use without registration.

Mind Map[edit | edit source]

!![edit | edit source]

Successful fork of that beloved FreeMind. Java is required. Very useful if you got confused by a grammar, but not only for grammar.

International Phonetic Alphabet[edit | edit source]

!![edit | edit source]

The site of the maker. The full IPA chart can be downloaded here. There is also a link to an interactive IPA chart.

!![edit | edit source]

IPA and romanization transcriptions. Very detailed, but there is a limitation for each hour. Its “More Tools” is also noteworthy.

Basic Course[edit | edit source]

!!!![edit | edit source]

The best free online language courses. It is actually a collection of exercises instead of real courses. Its mobile version doesn't have “tips and note”.

Don't neglect their other products.[edit | edit source]

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.

!!!![edit | edit source]

A promising challenger of Duolingo. It gives you plenty of tips, and new lessons are always based on previous ones.[edit | edit source]

Some super cool courses.[edit | edit source]

A little site with useful basic courses of 5 languages, with good design.[edit | edit source]

Material of native American languages.[edit | edit source]

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

Speaking[edit | edit source]

!![edit | edit source]

Dictionary of pronunciation.

!![edit | edit source]

Check your pronunciation through SR and TTS.

!![edit | edit source]

Submit the recording and wait for the response. Supported languages are not many.[edit | edit source]

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

!![edit | edit source]

Try not to hurt yourself when practicing.

Vocabulary[edit | edit source]

!!!![edit | edit source]

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.

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

Its app is quite worse than the web version. On the app, you can't add other courses besides official ones, and the download for offline use always fails if the vocabulary is over 3k.

In the app, don't look at the candidates (including candidate letters) at first, to aboid getting hints from them.

!![edit | edit source]

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.

!![edit | edit source]

Open-source and offline. Content can be in diverse formats. There are also add-ons for it.

In language learning, it is supposed to reduce impression of errors as much as possible. But when you are guessing the answer in flashcards, you may be deepening the impression of wrong ones.

Unfortunately, not free on iOS.

!!!![edit | edit source]

Learn with cloze. It is effective, but sometimes it is just repeating the same point in different questions.[edit | edit source]

Four languages to learn. There is a trial automatically started after you register, so don't expect all features will continue if you don't pay after 48 hours.[edit | edit source]

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

Also their browser add-on. Very good.

!![edit | edit source]

It focuses on visual training, which has both advantages and disadvantages. Free users have to wait 10 hours for the next 5 min practice session.

!![edit | edit source]

Simply learn words and sentences.

!![edit | edit source]

It's pretty good for educating young polyglots.

!![edit | edit source]

They may think “word of the day” is too inefficient, so do I. It is constantly being improved, but not satisfying for now. The response of a contact is quick and friendly.[edit | edit source]

Practice sentence translation through subtitles. Don't expect word-to-word translations.[edit | edit source]

Great idea of making use of wallpaper. Only for Mac, and languages are few.[edit | edit source]

Also, a great idea to learn a word each time you open a tab. Only for three languages. Only for beginners.[edit | edit source]

Frequency lists. Make use of it with software that helps to memorise, such as Anki. And if you would like, share with others.

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.

Maybe somebody can create a program to do it. This would be a great favour to the human.

There is a trick of making use of it: open two same pages, translate one of them, so if ignoring polysemes, it would be a convenient way of seeing their meanings.[edit | edit source]

For testing your vocabulary size. There is only one version of test.

Proficiency Test[edit | edit source][edit | edit source]

Test your proficiency. There is only one set of test for each language. It feels very good to see the progress of yourself.

Reading[edit | edit source]

!![edit | edit source]

Numerous articles in many languages and they are usually proofed to read.

Also take a look at its sister projects such as Wikisource.

!![edit | edit source]

Make Wikipedia and some other sites offline. Open-source. No doubt that you and all other people in your village or apartment can't read them all.[edit | edit source]

The largest collections of books in the public domain, mostly in English though.

!![edit | edit source]

Read and create flashcards to learn. The response of a contact is quick and friendly.

!![edit | edit source]

Bilingual stories. Voices are from volunteers, the quality is not very good.[edit | edit source]

As what its domain name says, parallel text. Classical works.

!![edit | edit source]

Articles in many languages, with online dictionaries. Bad news: its development is stopped.[edit | edit source]

List to find high-quality parallel text on some of those websites. Be careful about brainwashing.[edit | edit source]

Declaration: suggesting it is not for preaching.

The full Bible has been translated into at least 670 languages, more than double the number of languages of Wikipedia.

The site's counterpart in Islam is Declaration: mentioning it is not for preaching.[edit | edit source]

This is a PHP project. The page design is very bad, but as a learned person, you should have sufficient patience to read the guide and follow it. It's a DIY, offline and free version of LingQ.

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

Dictionary[edit | edit source]

!!!![edit | edit source]

Practical, no need to switch dictionaries, translations in many languages are shown together.

!!!![edit | edit source]

It is really completed.

!!!![edit | edit source]

It is completed, with example sentences of high quality. You can even find uncommon words with meanings of common words.

!!!![edit | edit source]

It is completed.

!!!![edit | edit source]

It supports so many languages, citing results from other sites. It is somehow messy and in many cases inaccurate, but if the dictionaries listed above have no result about a word, this one may help.

!!!![edit | edit source]

The best offline dictionary. Its update is stopped, but it is still very useful.

!!!![edit | edit source]

Unofficial Lingoes on Android.

!![edit | edit source]

It is open-source and supports several dictionaries in the free version, and also Lingoes in the paid Android version. No one would want to pay after knowing the link above.

Translator[edit | edit source]

!!!![edit | edit source]

The best translator by now. It also supports optical character recognition on mobile.

!![edit | edit source]

It supports several languages that Google Translation doesn't support, but its quality is not so good as Google's.[edit | edit source]

Instant translate with double-click, and create phrasebooks.[edit | edit source]

Translate to multiple languages at once.[edit | edit source]

Similar to Translatr, but it uses Microsoft.

Listening[edit | edit source]

!![edit | edit source]

Books read by volunteers.

!!!![edit | edit source]

Listen to songs and fill in the blanks of lyrics.[edit | edit source]

!![edit | edit source]

It can be called the best platform for Android.

Example Sentence[edit | edit source]

!!!![edit | edit source]

Example sentences in many languages. Open-source.

If you want to translate, translate sentences with audio first, because the translations may appear on sites which provide translations of audio.

Search for parallel texts in subtitles.

A different one to draw parse trees. Open-source.

Helper of memorization. Useful for building the impressions of sentence structures.[edit | edit source]

Cloze-like memorization.

It provides apps for both phrase and vocabulary, but I have categorized it in this one because it provides IPA in the apps of phrases.

There are some rare features of it, such as Wiki lessons, Events. It adopts ISO 639-3, almost every language is included here.

Questions & Answers[edit | edit source][edit | edit source]

Ask and answer with people around the world. Unfortunately, don't expect them to be effective in dealing with spamming and abusing. But I'm not encouraging you to do so.

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

Do not answer the meaning of a single word. The questioner should consult a dictionary on its own. Exceptions are newbies, because they may be following the tutorial, just want to have a try, not really lazy.

Do not feed the trolls.

Search before you ask.

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

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

The most popular site for Q&A.[edit | edit source]

Its advantage, also its disadvantage, is dividing itself into a lot of small sections. As learning language usually does not require inspirations from other fields, this one may be better than Quora.
