About RC Constant
RC Constant solves a specific problem that comes up daily for anyone dealing with this task: doing it once, fast, without an account. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.
