AI Pay is a tool that enables websites to be paid to implement AI. Develop an AI application using AI APIs such as Chat GPT, embeddings, and image generation without having to worry about, users, payments, monetisation, or even a server/backend. Focus on development and easily pass on AI costs to the users of the website. This mechanism benefits both parties: the website can improve its user experience through the advanced capabilities of AI, and the users get access to unique, value-added features. AI Pay works in combination with a browser extension. The users can specify a budget and start an AI Pay session on a specific website. As long as the session is active and there's a budget remaining, the website can leverage AI Pay to utilize AI APIs for free, aiming to provide an elevated user experience. The tool can be used to deploy open-source GPT apps, thus enabling users not willing to handle API keys or to self-host, to still enjoy the technology. Additionally, AI Pay can support the implementation of developer documentation chatbots for open-source developers, creating an alternate income stream. AI Pay proposes a unique monetisation model for websites. Websites earn a markup on AI usage costs. Additionally, if a user downloads AI Pay and uses your website first, you will receive 5% of that user's future credit purchases. Monetise your website with value adding AI instead of annoying ads. In summary, AI Pay is an effective solution that allows websites to enrich their user experience with AI, while also setting up a new revenue stream.
