Open Tool A quick note
Treat the result as an input, not the final decision.
Calculators depend on the numbers you enter. SEO and content checks are diagnostic, not rules that replace judgment.
Review the assumptions, check important financial or technical decisions, and use the output as a clear starting point.
Suggest a tool
Missing a small utility?
Send the recurring task plus an example of the input and result you need. That is enough to evaluate the idea.
Looking for something else?
For math and finance, browse the calculator library. For installable features, see the WordPress plugins. For implementation examples, visit the code snippets.
FAQs
Are these tools free to use?
Yes. The tools listed on this page are free to open and use. You do not need a paid plan to run a calculation, conversion, or content check.
Do I need to create an account?
No. You can open and use the tools without registering an account. If an individual tool ever needs an external service or additional setup, its page will explain that before you begin.
Is the information I enter stored?
Many calculators and checkers on this site run in your browser, so the text or numbers you enter stay on your device. Check the note on the individual tool page if a feature requires a network request.
Which tool should I start with?
Start with the task you need to finish. Use the Freelance Rate Calculator for pricing, the Keyword Density Checker for phrase repetition, the Email Marketing Cost Calculator for platform comparisons, or the HTML to GenerateBlocks Converter for WordPress markup.
Can I use the results for client work?
Yes, but review the output before acting on it. These tools support estimates and checks; they do not replace professional judgment, testing, tax advice, legal advice, or a proper project brief.
How can I suggest a new tool?
Use the contact page and describe the recurring task, the input you have, and the result you want. A small real example is more useful than a long feature list.
