One person, no accounts
Every tool here runs inside your browser. Nothing you type is sent anywhere, there is no signup, no mailing list and no profile of you. If a tool gives you a wrong number, write in and it gets fixed: the whole catalogue is generated from one place, so the fix lands on every page at once.
Why the pages look plain
They are built to open fast on a phone with a bad connection: one file, no fonts to download, no frameworks. The tool sits at the top, how to use it right underneath, and nothing else in the way.
How the site is paid for
Nothing here is for sale and nothing asks for an account. When the catalogue is complete and people are actually using it, the running costs get covered by advertising; if a tool ever points to a product that fits what you were already looking for, the page will say so.
The catalogue
12 tools in 5 groups so far, with more added every week. Start from all tools, or use the search box at the top of any page.
