Loom

Loom records your screen, camera and voice at the same time, so you can explain something once and share it as a link instead of booking a meeting or writing a long message. Viewers watch at their own pace and can comment and react on the timeline. Videos can be trimmed after recording, and AI features add titles, summaries and chapters.

It works through a Chrome extension, desktop apps for Mac and Windows, and mobile apps, with integrations for Slack, Gmail, Jira and others. Loom is part of Atlassian. There's a free plan with limits on video length and paid plans for teams.
