• Office 365
• Google docs
• Libre office
• Confluence

All of those answer the questions. Sure, libre office for example relies on everyone knowing what MS office is, but it still does a good job of explaining.

Again, I don't know exactly what your product does, but my guess is that confluence is the one that's more similar.

Don't need to look at your competitors though. Go to any product with a multi-million marketing budget and you'll see how they answer the basic questions in a similar manner.

Edit:

Of course if you look at what their product page looked like before the AI bullshit ate the brains out of the tech CEOs, you would find better examples.
