Small tools for the jobs you keep repeating
Most of us have a handful of tiny tasks we repeat all week: cleaning up a string, converting a format, checking a value. They're too small to write a script for, and the websites that solve them are often buried under pop-ups and sign-up walls. ToolPlank is a cleaner alternative.
Every tool lives on its own page and does one job. You paste your input, the result updates as you type, and you copy it. Under each tool there's a short guide with worked examples and straight answers to the questions people tend to ask, so you understand what the tool is doing and not just what it outputs.
Everything runs in your browser. The text you type isn't sent to our servers, which keeps your data private and the tools quick. The collection is small today and grows steadily, with new tools added based on what people ask for. Read more about the site and who runs it.
