What is the value in paying this massive cost when Teams, Zoom all support ootb?

Enabling transcription/recordings per platform and remembering to record creates user-dependent setup. Also the host often needs to install apps which adds security friction, and you still have to build/maintain separate implementations for Zoom/Meet/Teams which is often a cost that devs don't want to deal with

Instead, we built a single API that can get the same results without the issues mentioned above so you can focus on building the features your users care about
