As someone else pointed out, creating a good real time editing experience is tricky, especially if the editor is block based.

I would add Saga (https://saga.so) to the list of alternatives.

It is extremely offputting that Saga doesn't show a single actual product view, the site design makes me think the product is equally ugly, and they require signing up to see a demo?

When a company hides the product that much and forces you to only experience it with a tour guide, it's tacit admission the product sucks.

I agree that it's frustrating when a company hides their product, but I think the saga website design is really nice and they do have an actual video of the platform front and center (Instead of one of those fake simplified "representations" that may companies use).

The hero section of the website is a demo recording of the product.

"b2b software" and "wiki tool" are not mutually exclusive.
