This is a growing list of resources for language learners. Not a comprehensive list (yet), rather an array of, perhaps, lesser-known tools; though we hope it can be of use.
YouGlish.com: gives you fast, unbiased answers about how languages are spoken by real people and in context instead of what’s prescriptively correct.
Deepl.com: better than Google Translate.
italki.com: connect with other languages learners to practice your target language.
