Am I overthinking this, then? I'm trying to avoid having to resubmit my story. Last time I had to (for a different story) because I kept mixing up past/present tense, but I think I've got that under control now
Writing is something I have always been good at (lots of As on my essays and papers in school and that sort of thing) and am a bit of a perfectionist about (I nitpick my stories to death during editing). But not everyone is me. If you find a tool helps, then look into them. Probably find reviews, preferably by writers, to see what is good. Word processors don't really check for issues like you describe (and don't worry, I have made that mistake a couple times, too, as well as switching person from 1st to 3rd mid-story at least once) so a tool that does could be helpful. I would just rather keep my instincts and abilities honed by doing it myself.
