About

What this site is

utils.9odo.com is an index of small, single-purpose web tools. There is one tool listed today; the list on the front page is the complete one. Each tool is a separate static site published under its own path on this subdomain.

It is built and run independently, and is not affiliated with any organisation quoted or linked from the individual tools.

What the tools have in common

No accounts, no sign-up, no uploads. Where a tool takes input, that input is handled inside your browser and is not sent anywhere. Each tool carries its own about page describing what it does and what it deliberately does not claim.

Tools that carry advertising label it and keep it out of the first screen. This index page carries no advertising.

Reporting a problem

A wrong result matters more than a broken layout. If a tool gives you an answer you believe is incorrect, the useful report names the tool, the exact input, the answer shown and the answer you expected.
