Features
Seven things, in the order you meet them.
Or skip all of it — the button up top is the real thing, and it takes a paste.
01
Your text stays.
Paste, and it's exactly where you put it — editable, for the whole session. The tree arrives beside it when you ask, and folds away when you want room.
02
Broken input explains itself.
Dots on the lines, plain sentences, one button. Nothing changes until you say so, and undo is right there when it does. Or fix it yourself — it re-reads as you type.
03
Logs and CSVs ask once, beside your text.
Separator, header row, log pattern — asked with a live preview next to the lines you pasted. Never in a dialog over them. Never twice.
04
Every row carries its own tools.
Hover a row: Copy and Focus, right after the text. A value that holds packed data always shows Unpack — a finding about your data, not a feature you have to know about.
05
Compare by structure.
Two files, only the real differences. Reordered keys aren't a change. A log is matched by record, not by line order.
06
Wears your editor's colors.
Follows your system between light and dark. Or One Dark, Dracula, Catppuccin — the three most-installed editor themes, matched to the hex.
07
Nothing leaves your browser.
Reading, fixing, comparing — all in your tab. Open the network panel and watch it stay empty.
