There are many free tools that can translate blocks of text (or even entire documents) into another language. If you’re learning a new language, you can use them to check your written or spoken phrases. Or, if you’re trying to read or listen to information in a language you don’t know well, ask the tool to translate it for you. Remember, though, that no translation tool is perfectly fluent in any language – and all may struggle with the technical or advanced terminology in textbooks or peer-reviewed articles.
A few examples are linked below, but you can find others by searching the web for free language translation tools (or something similar). *Keep in mind that many of these applications offer limited services for free, and may prompt you to subscribe for more features.*
For translating academic or scholarly research papers, try Paperpal, which has limited free services.
