A good bet is to create an API for it and sell it on Rapidapi or some site, with a possible free tier.

I think a lot of devs would benefit from a good text summarisation algorithm (haven't tested yours just general advice) and since youre good at programming and not marketing make some npm modules, composer packages, gems and the whole shebang.

Soon you'll be making a few $k a month depending on how good and fast your api is. The free tier will help you get some search engine traffic. An on page demo is also very useful in this regard.

Also this has chance of landing some big co with deep pockets who just finds your product a good fit and couldn't be bothered to hire a dev to do this just yet. So make sure you have a $$$ unlimited plan. Good luck.
