Derivatives

About Derivatives

Derivatives was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.

When you'd reach for Derivatives

• You're hitting the daily limit of a paid SaaS and need a backup option for a single quick job.

  Stay productive without burning credits.

• You need to handle a one-off task right before a meeting and don't have time to install anything.

  Anyone working remotely on a borrowed or restricted machine.

  Open the page, get the result, paste it into your doc — under a minute.

• You're on a public or shared machine and don't want to leave traces of what you're working on.

  Travelers, contractors, anyone working from a friend's computer.

  Nothing is uploaded, nothing persists if you're not signed in.

• You're cleaning up a folder of files that accumulated over a project and need to standardize them.
