Unique and custom-fit texts for marketing and other usages. TextCortex was a great help for me, creating marketing texts for product descriptions on a homepage I am working on recently. Besides that I really like the idea of the pricing model, offering the service for free to young start-ups.

TextCortex helps me a lot with my school projects requiring me to write long essays. In such a short time, I could create long-form essay bodies from my bullet point ideas. Truly a life-saver for my studies. I also benefited from the Student Program.

This extension has a lot of potential; however, I feel it is in the beginning stages of development. The developers constantly add new features though. The AI writing ability is very good, just needs a few little tweaks worked out before it is perfect.
