Cap.so is not currently a supported video provider in Intercom, which means it won't auto-embed in Articles or outbound messages today. When you paste a video URL into the article editor, Intercom recognises a fixed list of providers - YouTube, Loom, Vimeo, Wistia, Tella, and others - and renders them as playable videos. A Cap.so URL would appear as a plain hyperlink or be stripped, depending on where it's inserted.
I foresee a massive exodus from Loom in the time to come (price + Atlassian admin burden). It has already begun.
While Tella is an alternative, pricing is largely the same as Loom. Zero gain.
Cap is much cheaper and more flexible.
The provider list has been extended for Tella, Storylane, Zight and others in recent cycles, and adding Cap.so is a contained change.
