Zight

Zight is a visual communication platform that allows users to capture, annotate, and share screen recordings, screenshots, and GIFs. It integrates with various productivity and communication tools to streamline workflows and enhance clarity in team collaboration and customer support.

Zight (formerly CloudApp) is a strong match for the asynchronous video communication platform concept. It explicitly offers screen recording, webcam recording, instant sharing via links, and basic video editing, which are all 'must-have' features. Additionally, it provides a comprehensive set of 'other' features such as viewer analytics, timestamped comments, emoji reactions, auto-generated transcripts, team library functionalities (implied by team/enterprise plans and file management), Slack integration, mobile app support, custom branding, password protection, enterprise security & compliance, and API access (SDK). The website content clearly details these functionalities across its various product pages (individual, teams, enterprise, features, integrations).
