When it works it works very well. About one half the time it signs it's self out. Doesn't pick up mistakes on Facebook. Adds commas where they don't belong.

Overall a great tool for grammar fixing but some parts could be optimized better. One tool that could be worked on it the layout of the pop out screen. Overall it seems a bit sparse and when fixing a problem you have to click on the right side bar which is annoying, it should be set to a hotkey in my opinion.

I liked this add-on very much. It caught my mistakes as I worked. Unfortunately, Firefox is blocking it now. Shame on Firefox.

Big help to me! definitely improves my writing!

A pesar de tener un plan gratuito bastante pobre (pocas opciones, pocas ayudas y muy poco escalable), la extensión (y la app) en sí funcionan muy bien. Si tuvieran mejores planes de precios sin duda me plantearía suscribirme.

Grammarly does make a few mistakes now and again but overall it has improved my writing.
