I've met a lot of creators over Twitter this week and many seemed to be figuring out what products they could offer their customers.

"I have an idea for a product but I'm not sure if people will buy it."

In the language of product management, this process is called finding "product-market fit," and there are well established systems you can use if you're in this boat (read: don't recreate the wheel).

If you want to get a sense of whether your product is compelling enough, test your idea before your spend months building it.

I've built a lot of digital products for Fortune 200 companies and startups across multiple industries, and these are some of the ways I test our product ideas before we build them:

Test your offer by creating a lead magnet (an asset like a "how-to" doc that is genuinely helpful for your target customer. In exchange, you can collect information about the potential customer. Pro tip: ask questions that will help the customer, i.e. "your answers will customize the doc we'll provide you."
Build a waitlist on your product to gauge interest. Advertise your product in spaces your ideal customers live in and see how many people sign up. You can even ask questions as part of the waitlist to better understand what your customers are looking for and let them know their needs will inform what you build. You'll learn 1) whether you can reach your target audience in the first place and 2) whether they're interested in signing up.
Build a prototype of your product and test it with real people. It actually takes 10 minutes to set up user interviews. I recommend using userinterviews.com because they specialize in finding niche users who fit your target demographics.
