About Plain Tools

Plain Tools is a small collection of free text utilities for writers, students, editors, and anyone tidying up a draft or a list.

Useful, without the overhead

Each tool does one clear job. The site uses plain HTML, CSS, and JavaScript, with no account system, database, paid API, or text-processing server. This keeps the product simple to maintain and quick to load.

How we fund the tools

Advertising is provided through Google AdSense. Display depends on site approval and your privacy choices. You never need to click an ad to use a tool.

Our content

Tool guides describe the actual behavior and limitations of each utility. These are formatting and reading aids, not substitutes for reviewing an important document. Japanese readings and source-word suggestions may need correction. We do not claim that outputs follow every editorial style guide.
