If it's hard to tell the difference, it'll be hard to sell the difference. (Cheesy rhyme intentional)

But seriously, you could probably do some research to work out your solution's strengths, relative to existing solutions.

When you know what it's strengths are, try to find people who want those strengths.

Ultimately, you're asking the question 'is there a market for what I've built?' - but you've phrased that question differently.

Everyone else is focusing on news articles as well, so that's not a problem; however without comparison to other approaches it's impossible to tell if the solution is 'powerful' or even any good at all.

This here - http://nlpprogress.com/english/summarization.html - would be an overview of what algorithms are currently considered 'good' and what results they achieve on some datasets commonly used for evaluation and comparison, it would be interesting to run your solution on that data and see what you get.
