Why the Keyword Density Checker is different
Browser-native
The Keyword Density Checker runs entirely in your browser. Input is processed locally — never uploaded, never logged, never cached anywhere outside your device.
No artificial limits
No daily quotas, no character ceilings, no "upgrade for more" walls. Every feature is the complete feature — the same on the first use as the thousandth.
Production-grade quality
Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
Common use contexts
- Pre-publish content review to catch keyword stuffing
- Competitor page reverse-engineering — see which terms a top-ranking page emphasizes
- Auditing AI-generated copy for unnatural repetition patterns
- Optimizing landing page copy around target keyword
Private and secure
Zero upload
All processing happens in your browser. Input is never transmitted, logged or cached.
Works offline
Once the page loads, the tool runs without an internet connection. No network calls happen during use.
No tracking
No accounts, no cookies for tool state. Only aggregate analytics count visits at the page level.
