Frequently asked questions

Are the tools really free?

Yes. Every tool on the site is free to use without an account. The site may show clearly labelled advertising to cover its costs, but you never have to interact with an ad to use a tool.

Do you upload my files or text?

Most tools run entirely in your browser, so your data never leaves your device. Tools that need our server, such as website checkers, say so on their page, and any uploaded files are deleted automatically shortly after processing.

Do I need to create an account?

No. There is no sign-up. Tools such as the resume builder can save your work in your own browser so you can continue later.

Can I use the output commercially?

Yes. Results and documents you create belong to you. Please review generated documents, such as policies and invoices, before using them, because they are drafts and not legal or tax advice.

How can I suggest a new tool?

Use the contact form. We read every suggestion and prioritise tools that many people ask for.

Private by design

Most tools process data in your browser. Server-side tools are labelled and delete files automatically.

Free, without catches

No account, no paywall and no locked features. Ads, when shown, never block a tool.

Transparent results

Calculators show formulas and assumptions so you can check the numbers yourself.
