What tool do you wish existed? I'll build the top ones.

Hey everyone — I'm the maker of Plexto.

I built this because I kept bookmarking a dozen single-purpose tool sites, and I figured there should be one place. 200+ tools live right now, but I'm actively adding more every week based on what people actually ask for.

So: what's a tool you've needed recently but couldn't find a good free version of? Doesn't have to be complicated — half of what's on Plexto started as "I wish this existed" from someone.

There's also a "Suggest a tool" form right on the site (on the Contact page) if you'd rather submit privately, but I'd love to hear ideas here too so others can weigh in.
