A tool to keep SaaS spend in check. Am I missing something obvious?

I run into this problem a lot: sign up for SaaS tools…

...and months later we’re still paying for stuff nobody uses.

So over the weekend, I built a scrappy prototype that:

• Auto-detects all your active SaaS subscriptions

• Gives simple money-saving suggestions

• Sends ongoing alerts so you’re never surprised by a bill

I've included a demo video (comments).

It’s barebones right now.

I’d love to know:

• Would this actually be useful in your workflow?

• What’s the “must-have” feature I’m probably ignoring?

Just trying to know if others are facing similar problems and is it worth building or not? If it is what all features would be helpful for the community.

Would love your feedback on it.
