Symbl.ai is an API platform that enables developers to add machine learning to their sales workflows by analyzing voice, video, or text conversations. It provides a range of APIs, including Async API, Experience API, and Summary API, which can be used to process meeting or call recordings, create summaries, and provide insights into customer conversations. The platform's public workspace on Postman allows developers to easily get started with Symbl.ai's APIs and automate sales processes from cold calls to follow-ups. With Symbl.ai, developers can reduce the time it takes to make an API call and access pre-built experiences that simplify the analysis of vast amounts of conversation data. The platform is designed to help developers create new experiences throughout the entire communication touchpoints of the sales process, enabling them to transform recorded calls into intelligence for their sales teams.
