How is "use case" different from a product category?

A category groups by what kind of product something is — CRM, observability tool. A use case groups by the job you're trying to get done, like "track SaaS spend" or "onboard new hires," which can span several product categories. If you know the outcome you want but not the product type, start here instead of the category tree.

What if my exact use case isn't listed?

Use cases here are the common, recurring ones people search for — genuinely one-off needs won't have a dedicated page. Try the closest listed use case, or fall back to search, which matches on product descriptions rather than a fixed list.

Can one product solve multiple use cases at once?

Yes, and that's flagged explicitly rather than hidden — a listing under one use case will note when a product also covers an adjacent one, since a single tool that covers two needs is often the better call than two narrow ones.
