AI Analysis

●MidNiche GemCozy

Lightweight Hz checker in 17KB, but mouse polling rate testing is already commoditized.

Strengths

•Zero-permission extension using performance.now() for local interval measurement is privacy-respecting and fast
•8-second test + grading (S/A/B/C) gives gamers instant actionable feedback without leaving browser
•Real-time chart visualization during test is polished UX for the niche

Weaknesses

•Mouse polling rate testers already exist (browser sites, OS tools, vendor utilities)—no differentiation beyond convenience
•Limited audience—only gamers/reviewers care; hardware manufacturers already benchmark in-house

Post Description

I built a Chrome extension that measures your mouse polling rate directly from the browser toolbar.

Move your mouse over the popup for 8 seconds and it gives you: - Average polling rate (Hz) - Peak Hz and low 5% threshold - Jitter percentage and stability score - Performance grade (S/A/B/C)

No permissions required, no data collected, all processing happens locally in JS using performance.now() to measure mousemove event intervals.
