Vectorly is a software development kit (SDK) that uses artificial intelligence (AI) to upscale and enhance video in real time on users' devices, as they watch it. The company's mission is to provide a technology that streams low-resolution video content and watches it in high definition, allowing users to access online learning resources despite limited internet bandwidth. Vectorly has 100 AI models on its server, which are used for various purposes such as AI upscaling, virtual background replacement, and more. The SDK allows companies to integrate the AI-powered technology into their video applications, with a focus on performance and frame rate to avoid overloading low-end devices. Vectorly's tech stack consists of JavaScript, WebGL, and MongoDB, which is used to track and store event data and basic metadata. Sam Bhattacharyya, the founder of Vectorly, chose MongoDB due to its intuitive nature and the fact that it uses JSON notation for database storage, making it a great fit for his JavaScript-based project.
