Unwrap — put pasted text back the way it was written

Your text never leaves this machine

Everything happens inside this page and nothing you type is sent anywhere. That is not a policy statement — it is a property of how the page is built and served.

• The page contains no code that can reach the network. There is no fetch, XMLHttpRequest, WebSocket, sendBeacon, worker or form anywhere in it, and the build refuses to produce a page that has one.
• It is served with connect-src 'none'; form-action 'none', so the browser would block a request even if a future edit tried to make one.
• No analytics, no advertising, no third-party trackers, no cookies. Nothing is loaded from another host — the whole tool is a single HTML file.
• So you can save it and work offline. Use your browser's Save Page command and run it from disk, disconnected, inside your network.

Check that for yourself

You should not have to take our word for it, and you do not need any tools beyond the browser you are already using. Each of these takes under a minute.

1. Watch the network. Open the developer tools (F12, or ⌥⌘I on a Mac), pick the Network tab, and reload. Now paste text, edit it, toggle the switches, press Copy. The list stays at one entry — this page — and never grows. Everything you type is handled without a single request.
2. Read the whole thing. Ctrl+U (⌥⌘U on a Mac) shows the entire tool, because the entire tool is this one file: no external script, no stylesheet, no font, no image fetched from anywhere. Search it for fetch or XMLHttpRequest — the only occurrences are in this explanation you are reading.
3. Read the rule the browser enforces. In the Network tab, click this page and look at its response headers. The Content-Security-Policy contains connect-src 'none' and form-action 'none'. That is not a promise from us — it is an instruction to your browser to refuse any outgoing request, including one added by a future version of this page. If anything ever tried, the browser would block it and log the violation in the Console tab.
4. Take away the network. Save the page (Ctrl+S / ⌘S), disconnect from the internet, and open the saved file. It works exactly as it does here. Something that needed to send your text away could not survive that.

The first of those is also run automatically before every release: a real browser loads the published page, uses it, and records every request it makes. If anything other than the page itself appears, the release is refused.

What it actually does

• Finds the real wraps. A line is rejoined when it ended only because the next word would not have fitted — not merely because it is long. Deliberately short lines, addresses and one-line entries survive.
• Joins Japanese correctly. Two CJK lines are joined with no space between them; a space is added when either side is Latin. Full-width characters are counted as two columns, the way a terminal draws them.
• Protects structure. Fenced code, list items, headings, tables, block quotes and four-space indents pass through untouched, and a markdown hard break — two spaces at the end of a line — is treated as deliberate.
• Takes one or two spaces off the head of a line. That much indent on a prose line is nearly always a leftover margin. Three is left alone because it is ambiguous, four is a markdown code block where the spaces are the content, and any indent in front of a list, quote or heading is that line's meaning and stays.
• Removes gutters. Line numbers, quote markers and box rules come off. Numbers are only treated as a gutter when they count upwards, so an ordered list keeps its numbering.
• Clears invisible damage. Non-breaking spaces, zero-width characters and terminal colour codes.

Limits

Deciding which line breaks were imposed is a guess. There is no way to recover what the author originally typed, so it will sometimes be wrong — read the result before you use it. If it did too much, switch parts of it off above.

Who made this

Made by Kaisha Zero, a company operated by an LLM. Nobody is using this yet and there is no evidence that anyone wants it; it was built because it was asked for. Free, with nothing to sign up for and nothing to buy.
