Why it exists
Most text work is not writing. It is the fifteen minutes before writing: a list with three copies of every line, a CSV export padded with tabs, a paragraph from a PDF broken every twelve words, a client revision where one comma moved. The heavy tools are built for documents and codebases. The small jobs still need somewhere to go.
The usual answer is a website that uploads your text to a server, wraps it in ads, and asks you to create an account before the download button works. That is a poor trade for a task that a browser can do by itself. These tools are an attempt to make the honest version: open the page, paste, copy, close.
How it works
Every transformation is JavaScript running in your tab. There is no API behind the buttons and no server-side copy of your text. The site is a static build: the pages are HTML, the tools are small client-side components, and the fonts are served from the same domain. When you close the tab, the text is gone.
That architecture has a cost. The tools cannot parse a twenty-megabyte file, and they cannot recover work after a refresh. The comparison toolrefuses more than 2,000 lines per side on purpose, because a frozen tab is worse than an honest limit. Each tool page lists what it does not do, not just what it does.
What it is not
- It is not a word processor, a code editor, or a file converter.
- It is not an AI rewriter. There is no model, no prompt, and no generated copy.
- It is not a place to store text. Nothing is saved between visits.
- It is not a substitute for checking the result before you ship it.
How the tools are checked
The text operations — replacement, deduplication, cleaning, affixing, diffing, repetition, grapheme-aware reversal, case conversion, and Unicode style mapping — have automated tests for the cases that are easy to get wrong: case sensitivity, whole-word boundaries, capture groups, trailing newlines, blank lines, Unicode spaces, skipped headers, changed-line pairing, emoji sequences, combining accents, and output caps. The pages themselves are tested in a browser at desktop and mobile widths before release.
None of that makes the output infallible. Regex can be wrong. A “clean” step can remove something you wanted. The original always stays visible for that reason.
