I build free online tools that run in your browser, so your files stay on your own device.

About me

I have built many online tools, and I have also worked with a team to roll out enterprise applications.

I don't write the code myself — I decide the direction, the features and the finished result of each tool, and I build and verify it with AI assistance.

This site exists for one simple reason: I want everyone to have a tool that fits them. So far that means everyday tools and AI tools; AI tools built for teams come next.

What I work on

I build free browser-based tools — calculators, converters, generators and utilities — that run on your own device. Your files are processed in your browser and are never uploaded. You can browse the full tool list or start with the AI tools.

How this site is made

I decide what each tool does, how it should behave and what the finished result has to look like. The implementation is produced with AI assistance under my direction, and I verify the result in a real browser before it goes live. Tool descriptions are drafted with AI and reviewed against a fixed checklist. The details are published in the editorial policy, and the testing method is documented on the how we test page.
