Provides quick, offline access to a scientific calculator without needing to open a separate application or website. Solves the need for fast mathematical calculations (including trigonometric, logarithmic, exponential, and algebraic operations) while browsing or working.

User clicks the extension icon or presses Alt+S to open the calculator popup. The calculator displays in a compact popup (or can be opened in detached mode via context menu). User performs calculations using mouse clicks or keyboard shortcuts. State (display, memory, mode) is persisted in localStorage and restored on next open. All computation happens locally in the browser with no network calls.

Target users: Students / Engineers and scientists / Anyone needing quick scientific calculations while using Chrome

The extension is small and self-contained, making the analysis straightforward. No obfuscated code or complex service integrations to evaluate.

No login, account, auth, or session management code exists anywhere in the source.
