Sendspark

Sendspark is a strong match for the concept of an asynchronous video communication platform. It explicitly offers screen and camera recording, instant shared links, and robust analytics. While it heavily emphasizes AI personalization for sales, its core video recording and sharing functionalities align well with the 'must-have' features. It also offers many 'other' features like a video library, basic editing, auto-captioning (transcripts), password protection, and various integrations including Gmail and Slack (implied through '50+ email integrations' and 'send through sales tools'). The mention of a desktop app and Chrome extension covers mobile app support for recording. API access is also explicitly stated.
