OPLingo is a community-oriented, non-profit language learning site. It essentially combines the functions of LingQ, LangCorrect, Readlang, iTalki, and HelloTalk.
The free version gives you limited access to some functions, but by paying for a membership you support ethical causes — such as building a primary school in Tanzania.
You can browse user-contributed texts or easily import your own YouTube videos, articles, or ebooks into the Reading Tool. OPLingo has also developed hundreds of audio conversations in several languages, including Tagalog, Cebuano, Thai, Swahili, and Russian.
Within each page, you can read a transcript and get definitions and pronunciations of unknown words. By identifying which words you don’t know, the next passages you read will highlight the number of known or unknown vocabulary words.
In their Write & Correct section, you can write in over 100 languages and exchange corrections with other users, although Spanish, French, and English learners have a better chance of receiving corrections than other languages at the moment.
You can also practice a language by texting with fellow community members, or by hiring a teacher in your target language.
OPLingo has a lot of potential and is a good alternative to LingQ, but it needs a community of learners to help it grow — so check it out!
