Every tool on this page runs entirely in your browser. Nothing is sent to a server. Nothing is stored unless you choose to save it yourself. I built these because the tools I kept recommending to students either required accounts, showed ads, or stopped working after a few months.

These won't. They're simple, they do one thing well, and they'll keep working as long as you have a browser.

Why local-only tools matter

When you're studying, the last thing you need is another app asking for your email. These tools are designed to reduce friction, not add to it. Open the page, use the tool, close the page. That's it.

If you find a bug or have a feature suggestion, use the contact page to let us know.
