Test website for English teachers

Test functionality of tools for English teachers on website. Also test website functionality in general. Use at least two devices. Write about what devices and browsers you used, what worked, what didn't work, any other thoughts. Tools are here: https://polyglotmedia.com/tools/. You do not need to make an account or use the paid tools.

It is good if you are an English teacher yourself, however, this is not required.
