> So I made 25+ tools that:
> - Run 100% in your browser: — no server, no data collection
> - Load instantly: — pure HTML/CSS/JS, no frameworks
> - Cover real needs: — mortgage calculators, BMI, unit converters, AI model comparisons, regex testers, and more
> - Work offline: — once loaded, you can disconnect and everything still works
>
> The AI tools section is what I'm most excited about — comparing ChatGPT vs Claude vs Gemini pricing and features in one place, since that information is scattered everywhere.
