Undetectable Mouse Jiggler: How Still Here Simulates Real Human Activity

Not all mouse jigglers are created equal. Basic tools move your cursor in circles — a pattern that modern activity monitoring software can spot instantly. Here's how undetectable mouse jiggler software actually works, and what makes Still Here different.

Why Most Mouse Jigglers Get Detected

Traditional mouse jigglers — both hardware USB devices and basic software tools — use predictable patterns:

• Fixed-interval movement — Moving the cursor every exactly N seconds
• Small circular patterns — The cursor traces the same path repeatedly
• Mouse-only activity — No keyboard input, no scrolling, no app switching
• Pixel-level precision — Movements are too smooth, too perfect to be human

Activity monitoring tools like Hubstaff, Time Doctor, and ActivTrak analyze activity patterns. When they see perfectly timed, mouse-only input with no variation, it's flagged as suspicious.

How Still Here Simulates Real Activity

Bézier Curve Mouse Movement

Real human mouse movement doesn't follow straight lines. People overshoot, correct, accelerate, and decelerate. Still Here uses Bézier curves to generate mouse paths that look natural — with acceleration, deceleration, slight overshooting, and random variation in both speed and direction.

Keyboard Typing Simulation

A mouse jiggler with keyboard simulation is dramatically more convincing than mouse-only tools. Still Here simulates typing at configurable words-per-minute with natural variation between keystrokes. This generates the keyboard activity signal that monitoring tools look for.

App and Tab Switching

Real computer use involves switching between applications. Still Here simulates Alt+Tab and Ctrl+Tab to switch between open windows and browser tabs, creating the multi-application activity pattern that matches genuine workflow.

Random Click and Scroll Simulation

Clicking and scrolling at random intervals adds another layer of realism. The timing is randomized within configurable ranges, so there's no detectable pattern.

Real App Integrations

The Phantom plan takes it further: Still Here actually opens and interacts with real applications via CLI. VS Code opens with real project files. Slack, Teams, and other apps are brought to the foreground. This creates genuine application-level activity, not just input simulation.

What Makes It Undetectable?

Several factors combine to make Still Here's activity indistinguishable from real use:

• Randomized timing — No fixed intervals. Every action has a random delay within a configurable range.
• Multiple input types — Mouse, keyboard, scroll, click, and app switching happening together.
• Natural motion patterns — Bézier curves, acceleration/deceleration, and slight imprecision.
• System tray operation — No visible window, no suspicious processes.
• No network traffic — Nothing to detect on the network. All simulation is local.
• Native input events — Uses system-level APIs (pynput, Quartz on macOS) that generate the same events as real hardware input.

Safety and Privacy

Still Here is designed to be a safe mouse jiggler software:

• No data collection — nothing is sent to any server
• No browser extensions — nothing to appear in extension lists
• No system modification — doesn't change any system settings
• Instant stop — Ctrl+0 halts everything immediately
• System tray only — completely invisible during operation
