Many terms used in clinical research are complex and difficult to translate into vernacular languages. Using freely available tools on the internet for translations may lead to inappropriate or out-of-context translations. Interpreter is a tool that provides simple interpretations of commonly used complex terms in clinical research. The interpretations available on the tool are validated by experts and members of accredited ethics committees. Currently the interpretations are available in Hindi, Marathi and Tamil. More languages will be added in future.
