Small tools, built for conveniencehttps://toolbox-notes.pages.dev/enhttps://toolbox-notes.pages.dev/en/posts/hello-toolbox-notes/https://toolbox-notes.pages.dev/en/posts/hello-toolbox-notes/Why this blog exists: notes on the small tools I build to make everyday work easier.Thu, 05 Nov 2026 00:00:00 GMT<p>Every so often a task comes along that is just annoying enough to repeat — copying numbers between sheets, checking the same pages every morning, renaming a pile of files. At some point it becomes faster to build a small tool than to keep doing it by hand.</p> <p><strong>Toolbox Notes</strong> is where I write those tools down.</p> <h2>What you'll find here</h2> <p>The topics won't be limited to one field. If I built something because I needed it, it can end up here. For each tool I'll try to cover:</p> <ul> <li><strong>The problem</strong> — what was slow, error-prone, or tedious before</li> <li><strong>What the tool does</strong> — the main features, with screenshots</li> <li><strong>How to use it</strong> — enough detail that you could try the same approach</li> <li><strong>What I learned</strong> — the mistakes and surprises along the way</li> </ul> <h2>Up next</h2> <p>The first tool I'll write about is a helper program for managing an Amazon seller account — the day-to-day checks and number-crunching that eat up time when you sell on Amazon.</p> <p>This blog is available in English and Korean.
