Digital Research Tools for Linguists (and Other Researchers)

This week I had to prepare a list of digital research tools, i.e., desktop programs (for Windows and sometimes also for other operating systems) and online services, that in my opinion facilitate and enhance research input and output, and sent it to a certain group of linguists. I expand and reproduce it here, hoping that it might also benefit other linguists as well as researchers in other areas and simply anyone who wants to get things done efficiently. I myself use (most of) these digital research tools. All of them, except for EditPad Pro, are free.
