BFF is an AI-based tool designed to engage users in daily interactions about their life, including areas such as career, goals, relationships, and emotions. It functions akin to a conversational diary that interacts with the user. BFF contacts the user through text, offering a personal, daily touchpoint for discussions that commonly revolve around personal development and emotional well-being. The tool’s framework is rooted in advanced AI technologies. BFF is available in multiple tiers to suit the different needs of a diverse user base. The free tier provides limited interactions per day, using GPT-3 technology. The premium tier, known as ‘Pro’, enhances the user experience by offering unlimited messages and enhanced cognitive capabilities, powered by GPT-4, an advanced version of the AI. The Pro version has the added capability of learning about the user over time, aiming to provide interaction that becomes progressively more personalised. BFF is integrated and available for purchase in iMessage.
