SapienAPI is an AI tool that allows websites to enhance their customer experience by using large language models (LLMs) to understand natural language and provide contextual information from the web. It eliminates the need for migration or new infrastructure by seamlessly integrating with existing APIs. The tool enables websites to provide human-like responses to user queries, simplifies complex inputs, increases user engagement, and boosts conversion rates. SapienAPI can be easily integrated into existing systems and offers trustworthy AI by providing reasoning behind its outputs and reference sources. It leverages the technology behind ChatGPT and Bing AI, making it the easiest way to use LLMs without the need for managing GPUs, fine-tuning models, or testing out prompts. The tool is priced on a pay-as-you-go basis, is cheaper than GPT3.5 and GPT4, and offers the first 500 API calls for free. SapienAPI aims to transform how websites handle user queries, automate conversations, and deliver personalized solutions that resonate with users.
