DoNotPay, an AI-based chatbot app created to help fight parking tickets in the UK, now addresses roughly 1,000 consumer concerns and is available throughout the United States as well as across the pond. The app's creator, Stanford student Joshua Browder, announced the expansion last week. Powered by IBM Watson, DoNotPay has about 1,000 bots capable of tackling a variety of legal and service issues, ranging from fighting one's landlord to appealing against unreasonable warranties, to getting a refund when a company doesn't fulfill its promise.
