This is exactly the stuff that I think LLMs are best at. We have created the world's coolest string manipulator and this is exactly the kind of things I think LLMs are best suited for. Awesome job!

How do you ensure the titles aren’t confabulated? I’ve used Kagi News recently and it summed up the articles about France wrong (that’s the only section in which I could reliably spot the made-up stuff).

Cheers and thanks for the kind words! And yes - LLMs (at least o3-mini) do a great job as my editorial team - the site is 100% automated.
