Grammarly AI: The sweet spot of deep learning and natural language processing

Last week, Grammarly secured $90 million in funding for its artificial intelligence–based grammar and writing tools. But this specific case drew my attention because amidst all the hype and confusion surrounding artificial intelligence, I believe that Grammarly is solving a real problem. Understanding and processing natural language are among the most challenging areas of AI. Many companies have engaged in ambitious AI-based language projects. But a considerable number of them have failed miserably for not having considered the limits of current AI technologies. Meanwhile, Grammarly has found a niche suitable for the narrow capabilities of deep learning, the current bleeding edge of AI.
