Logrith, the free tool website I run as a side project

Logrith is a website with more than 100 free tools that run in your browser. I run it as a side project, mainly to earn a small, stable side income from ads. This is the honest story of how it started, what it is today, and how much it has actually achieved so far.

Why I started Logrith

I started Logrith for one simple reason, which was side income through ad revenue. I did not begin with a big mission or a problem that kept me awake at night. I wanted a project that could slowly earn something by helping people finish small tasks online.

Free tools are a good fit for that. People search for them every day, each tool solves one clear problem, and a site with many of them can grow page by page. That was the whole plan.

How I got the name

I picked the name Logrith at random. It sounded clean and I liked it, so I bought the domain.

Only after buying it did I find the problem. The word is close to logarithm, so search results for it are crowded with maths pages. That makes it harder for people to find the site by its name. If I could choose again, I would test how a name behaves in search before paying for it.

What Logrith is today

Logrith has 107 tool pages sorted into seven categories, along with a blog of 42 guides and a set of standard pages such as About, Privacy, Terms and FAQ. The tools cover everyday jobs, like compressing an image, merging PDFs, calculating a loan, counting words or formatting JSON.

I do not know which tool is the most important, and I have not picked a favourite. Some of the tools people may recognise are the Image Compressor, PDF Merge, QR Code Generator, Password Generator, JSON Formatter and Age Calculator.

Browser first and private by design

Almost every tool runs entirely inside your browser. Your files and text are processed on your own device, so they are not uploaded to my servers. The pages are written in plain HTML, CSS and JavaScript, with browser features such as Canvas and the Web Crypto API, plus open libraries like PDF-Lib and PDF.js for PDF work.

Two features are the exception because they need a server. One sends an email, and the other analyses the speed of a website. Anything that has to leave your browser is a different case from a tool that works offline, and I want to be clear about the difference.

The site collects only anonymous analytics, such as page views and which tools are used. It does not collect your files, passwords or text input, and there are no accounts to create. The full details are on the Logrith privacy page.

How AI helped me build it

I used AI throughout the build, for the code, the tool pages, the articles and the search optimisation. My part was the direction. I decided what to build, gave the instructions and checked the results. I do not present Logrith as something I coded alone.

That matches how I work on everything else on this site. AI does a large share of the implementation, and I take responsibility for the decisions and for what gets published.

The real numbers so far

Logrith is still early, so the numbers are small. In the last three months, covering August, September and October 2026, the site got about 34,000 impressions in Google search and about 170 clicks.

These are small numbers, and I would rather say so than dress them up. Impressions show that the pages are being found. Clicks show that very few people are choosing them yet. That gap is the main thing I need to work on.

What I learned

The biggest lesson was about the name, as described above. A name that is close to a common word can be hard to rank, and I found that out too late.

I also learned that building many pages is the easy part. Getting them to be found and clicked is much harder, and the numbers above show it. I did not hit one big technical wall while building, so there is no dramatic problem to report.

Where Logrith is going

The plan is simple. I want Logrith to become a stable source of side income, nothing more. It is a side project, and it is not my main long-term ambition. I will keep improving the tools and the guides, and I will report the numbers honestly as they change.
