You call the pharmacy. A cheerful robot says, "Please listen carefully, our menu options have changed." You press 1, then 4, then 2. You say "representative" like a magic word. Hold music. Then the call drops. You start over. We've all lost an afternoon this way.

Redial calls the phone menu for you. The first time, it explores the maze, listens to every option, and saves the exact path to a human in MongoDB. Every call after, it skips the thinking. It reads that path, taps the buttons in a one-second burst, and reaches a real person in about 20 seconds. Zero AI needed.

When a company reshuffles its menu, Redial spots the change, relearns only the part that broke, and fixes its map. A cache goes stale. Redial's memory heals.

Call once. Never fight the menu again.
