It is clear that 50Languages aims to make language learning accessible to anyone with an internet connection There is no signup required to use the site, so its resources are both free, and anonymous. You can find 100 free downloadable audio files of native speakers and ‘lessons’ in over 50 languages, in addition to vocabulary, alphabets, quizzes, and games.
Unfortunately, none of these resources follow a cohesive learning path, nor does the platform help you memorize any of the information provided. Only one section, the Translation Trainer, aims to help you retain phrases. However, if you have saved phrases in multiple languages, all of them will be bunched together into one review without an indication of which language you should be translating into.
The audio files and phrasebook lessons contain a series of phrases that do not seem to build on what you have previously learned; learning from this website is essentially like referencing a phrasebook you might buy for a trip to another country.
50Languages has a lot of information available, but it doesn’t seem like it can be used as a standalone language resource. Perhaps you can take phrases and vocabulary that interest you and compiled them into an Anki deck to help with retention.
The current rating is our best estimate. We haven’t had the opportunity yet to more thoroughly evaluate this resource, as we do for our full reviews.
