About NovaTools — who builds it and how it works

NovaTools is 498 single-purpose tools that run inside your browser. No account, no upload, no server doing the work. This page explains what that means in practice, how the site is built, and how it pays for itself.

What it is

Most of what people search for online is one small job: count the words in a paragraph, work out what 1080 × 1920 crops off a photo, check whether a caption is over the limit, turn a timestamp into a date. Each of those is a few lines of code. None of them needs an account, a subscription, or a file upload.

NovaTools is 498 of those jobs, each with its own inputs, its own logic and its own address. 109 of them are for social media — exact placement sizes, real character caps, and the arithmetic behind engagement and reach.

What “runs in your browser” actually means

When you open a tool here, your browser downloads a page and then does the work itself. There is no request that carries your text or your image anywhere, because there is no endpoint to carry it to. The site is a static file on a content delivery network; it has no database and no application server.

You do not have to take that on faith. Open your browser's developer tools, switch to the Network tab, and use any tool on the site. You will see the page load and then nothing further. If you want to be thorough, load the page, turn your Wi-Fi off, and keep using it — everything still works, because everything was already there.

Including the AI ones Three tools are labelled prompt builder. They do not call an AI service — there is no server here to call one from. They assemble a well-formed request and copy it to your clipboard, and you decide where to paste it.

How it is built

The whole application is a single HTML file with the styling and the code inside it. There is no framework, no build step and no dependency that can go unmaintained and take the site down with it. That is not nostalgia; it is what makes offline use, instant loading and a truthful privacy policy possible at the same time.

The long tail of tools comes from tables rather than from copy-pasted functions. Every social placement size, every character limit, every unit pair is a row of data that the page turns into a working tool. When a platform changes a size, the fix is one number.

What it is not

There is no image generator, no voice cloner, no video generator and no chat assistant built into this site. Those need a model API and a server to pay for it, which is the opposite of everything above. They are listed on the roadmap as things that are not here, rather than as cards that open and do nothing.

There is also no inflated tool count. A catalogue gets to five hundred by counting a converter's dropdown options as separate products; this one does not. “Resize for a YouTube thumbnail” and “resize for a TikTok” are two entries because they give two different correct answers. “PNG to JPG” and “PNG to WebP” are one entry, because they are one tool with a dropdown.

How it is paid for

Hosting a static file costs almost nothing, which is the only reason a site like this can be free without a catch. Advertising covers the domain and the time. There is no paid tier holding a feature hostage, and the tools do not degrade if you block ads — they are the same code either way.

If ads are running when you visit, they are clearly labelled and they are never placed inside a tool panel. See Pricing for the full position.

Who runs it

NovaTools is run by an independent developer, not a company with a support department. That has one honest downside — replies take a day or two — and one real upside: a bug report tends to be fixed by the person who reads it. Get in touch.
