They have continued to improve the product over the years, and I love the integration with different sites while still staying out of the way.

It slows down firefox a lot unfortunately, and the user interface is quite confused, why not give a way to use the correcting tools all at once?

Add-on ignores its settings and runs on sites that are marked as disabled. If you want privacy you have to completely disable it.

I love it

Free account is very limited. 500 word count limit.

If you are a writer of any kind, ProWritingAid will be helpful. It is especially helpful for those who cannot see the typos they are making (like me). It also help when sentences simply do not sound right, by suggesting alternate wordings. And they are always working to improve its features (although that can sometime make it somewhat complicated to use).

Very slow in every website.

Politcally charged grammer fixes.
ProWritingAid lists the term "biological sex" as problamatic as it could "offend transgenders".

Please keep your grammer tool politically neutral.

Quit a good grammar checker. But when it is enabled, writing text become almost impossible due to delays and glitches.

This is an awesome addon and it is cheaper than Grammarly!!!
