A/B test blog titles and topics

I write long-form, deeply researched articles on obscure topics (mostly biotech related). I love writing them, but constantly worry that I'm wasting my time, and that no one will care about a post that I've invested days in.

I also fear that a post I'm proud of will go unnoticed because I'm not good at writing titles, or because my intro paragraph is a bit off. A title can make or break a post, but I have no idea whether a particular title is good or not.

I'm working on a tool that takes the guesswork out of writing titles and ledes, and lets you see what topics your audience likes before you write the full post. I'm close to done with the MVP but wanted to go ahead and share the landing page:

Would this be useful to any of the bloggers / writers out there?
