Why a Loom alternative is usually a different category of tool
People who go looking to replace Loom rarely want a better recorder. They want the thing that happens after: a video that is not just watchable but finished, and that does not live on a service they have to keep paying for.
That is the split. Loom optimises for the seconds between recording and someone else watching. Montaj optimises for the twenty minutes between raw footage and something you would put your name on publicly.
