Tools

A collection of useful utilities and tools I've built for various tasks.

Welcome to my toolkit. These are small utilities and tools that I find myself reaching for regularly. They're designed to be simple, fast, and effective.

Available Tools

Norwegian Validation

Validate Norwegian social security numbers, bank account numbers, and electricity meter numbers using official algorithms. All validation happens client-side for privacy.

Convert

A visual string transformation tool that lets you build custom data processing pipelines. Create nodes for encoding/decoding (Base64, URL, ROT13, JWT), split and join strings, and connect them to build reusable transformation workflows.

Philosophy

Each tool is built with the same minimalist approach as this site - focused on doing one thing well, with clean interfaces and efficient implementations.
