About Super/Sub
Most online tools for text and data formatting bury what you need behind ads and forms. Super/Sub takes the opposite approach: load the page, do the job, leave. Built to be the kind of tool you bookmark and use weekly: no surprises between visits, no degraded free tier, and a UI that gets out of the way. Like everything else in the text collection, it is free, ad-light, and works on mobile as well as desktop.
