Tools
Start from the device or symptom.
Every page runs a genuinely different test and explains what the browser can — and cannot — conclude.
Keyboard tests
Inspect key press and release events, repeats, combinations, ghosting and observed rollover.
Mouse tests
Check buttons, unwanted double-clicks, wheel direction and browser-delivered movement rate.
How it works
A useful answer in three steps.
Choose the symptom
Open the focused test that matches the behaviour you noticed.
Create a clean sample
Follow short guided actions while the browser reads local events.
Read the evidence
Get measurements, possible causes, limitations and sensible next checks.
Trust
Private by design, precise about limits.
InputAnalyzer analyses peripheral events in this tab. Advertising, analytics and payments — when enabled — use their own disclosed metadata, never your raw key sequences, stick traces or pointer paths.
