Open-ended tools can have the zombo.com problem.

Zombo.com is a joke website from the early internet that had an over-the-top landing page that stated that "You can do anything at all on zombo.com," but had no actual functionality.

Even if your tool is a real one, if users land on it and have no idea what to do with it and thus can't get it to do anything useful, you could inadvertently have created effectively a zombo.com.

This is possible if you can do "everything" but no individual use case particularly well, and with no affordances.

With open-ended tools it's important to have a clear starter use case for users so they can get a sense of what it can do.

Google Search and ChatGPT are two open-ended tools.

But they are both good enough at so many things, that no matter what you do as a first use case, you're likely to have a good-enough result that gives you an intuitive sense of what will work and encourages you to try again and use it more.

Another approach for an open-ended tool is to have deep links.

More savvy friends can send their less-savvy friends deep-links to specific use cases that will work well for what the less-savvy friend is trying to do.

The use case is more likely to work for the less-savvy friend to start, which keeps them using the tool and then exploring things it can do.

When there is a rich universe of secondary-use cases, the user can quickly get sucked into the secondary-use cases and expand beyond their primary use case.
