Frequently Asked Questions
Are ExpertsByTech tools free?
Yes. Every tool is free to use, with no registration, sign-in, or paywall, and nothing to install.
Does the Password Strength Checker send my password anywhere?
No. The Password Strength Checker runs entirely in your browser. Your password is analyzed on your device and is never sent to ExpertsByTech or any other server, stored, or logged.
Does the AI Prompt Enhancer send my prompt to an AI?
No. The AI Prompt Enhancer doesn’t use an AI model. It structures your prompt with best-practice templates and rules, and your text is processed in your browser and never sent to our servers or to an AI provider.
What does the SERP Previewer simulate?
The SERP Previewer shows an approximation of how a page's title tag, meta description, and URL may appear in a Google search result, including where long text is likely to be cut off. The preview is generated in your browser. Google can rewrite titles and snippets, so the live result may differ.
How does the ROI Calculator work?
Enter the amount you invested and the amount you gained or expect to gain. The ROI Calculator subtracts the cost from the gain to find net profit, then divides net profit by the cost and multiplies by 100 to give ROI as a percentage. The calculation runs in your browser.
