Every space gone, from any AI reply.
Free AI space remover. Strip every space, tab, line break and Unicode space from ChatGPT, Claude or Gemini text. In your browser, nothing uploaded.
The tool
This tool takes every whitespace character out of text copied from an AI chat assistant and gives you back one unbroken string. Ordinary spaces, tabs, line breaks and the Unicode spaces that look identical to a normal one all go. Paste the reply, press the button, copy the result.
It runs in your browser. Nothing is uploaded, there is no run limit and no length cap, because no server is involved in the work at any point.
Read this first
This matters more than anything else on the page. The tool does not collapse double spaces into single ones. It deletes all of them, so "clean my text" comes back as "cleanmytext". That is the right result for a slug, a key, a filename, a token or any field that rejects whitespace, and the wrong result for a paragraph you want to keep reading.
If you wanted spacing tidied rather than erased, two other routes do that job instead. The whitespace minifier collapses every run of whitespace down to a single space and trims the ends. The general text cleaner keeps your line breaks and tidies the spacing inside each line. Pick by what you want left behind.
How it works
Nothing to install, no settings to configure, no account.
The actual list
A dedicated space remover beats a find-and-replace on the space bar, because the space bar makes one character, U+0020, and several others draw a gap that looks the same. These are the ones this tool takes out.
Scope, stated honestly
Zero-width characters are not whitespace, so they are not touched here. That means U+200B the zero-width space, U+200C and U+200D the joiners, U+2060 the word joiner and U+00AD the soft hyphen all survive a run. They leave no visible gap, so nothing looks wrong, and that is exactly why people assume the tool failed.
If your problem is invisible rather than visible, use the AI watermark remover instead. It handles that class of character specifically. This tool also does not straighten quotes, convert dashes, strip markdown or count anything for you. It closes gaps, and that is all it claims.
The cause
An AI reply reaches your clipboard as rendered rich text, not as the plain characters on screen. HTML collapses a run of plain spaces down to one, so an interface that needs to show a visible gap has to use a character the browser will not collapse, and a no-break space is the usual choice. Code blocks, tables and lists all push extra whitespace in for layout.
Copy that render and you get the layout characters with it. The words are fine. The gaps between them are a mix of at least two kinds of character that look like one.
Why it matters
The failures are hard to diagnose because the text looks correct. A URL slug built from an AI-written heading resolves to a different address than you meant, because a no-break space sits where you thought a normal one was. A spreadsheet lookup misses on a value that reads identically to its match.
In code it is worse. A no-break space inside an identifier or a string literal produces a syntax error that most editors give no visible sign of, so you stare at a line that looks perfect. Removing every space before pasting a generated value into a config file takes the whole class of problem away.
Who it's for
Developers use it on values an assistant generated, an identifier, a config key, a sample token, before those values reach a file that will be parsed. Data people use it on a column of keys or codes that has to match exactly.
Anyone building a slug, a hashtag, a filename or a form field with a no-whitespace rule uses it the same way: paste, run, copy, and the value is now one string with nothing hiding between the characters.
FAQ
Everything below is answered in full, nothing to click open.
Paste it in and press the button. Every whitespace character comes out and you get one unbroken string back.
Every one. If you wanted doubles collapsed into singles, use the whitespace minifier instead, which leaves a single space between words.
Yes. No run limit, no length cap and no account, because the work happens on your own device.
No. The removal runs entirely in your browser. Open your network panel during a run and you will see no request go out.
Yes. Line feeds, carriage returns and the paragraph separators all count as whitespace here, so the result is a single line.
Yes. U+00A0 and the narrow no-break space U+202F are both removed, which is what most find-and-replace attempts miss.
No. A zero-width space is not whitespace, so it survives this tool. Use the AI watermark remover for U+200B and its relatives.
Most likely the characters causing the problem are invisible rather than spaces. Nothing widened or narrowed, so nothing looked different.
Because you are searching for U+0020 and the gap is a different codepoint that happens to draw the same width.
Yes. It reads the characters in your clipboard, so the interface they came from makes no difference.
Yes. There is no length limit, because nothing is being sent anywhere to be metered.
No. Letters, digits and punctuation are untouched. Only whitespace is removed.
No. That is a different tool. This one only closes gaps.
No. Use the markdown stripper for that. Hashes and asterisks are not whitespace and stay put.
No counters here. The word counter and token counter are separate routes.
Only if you want the indentation gone as well, since it removes every space including leading ones. For code, the general cleaner is usually the safer choice.
Yes, the same way, in any modern mobile browser.
Yes. Nothing is transmitted or stored, because nothing leaves the page.
Yes. The ideographic space U+3000 used in Chinese, Japanese and Korean text is whitespace and is removed.
Not currently. This is a single-document browser tool.
No. Odd spacing comes from how text was rendered and copied, not from who or what composed it.
Runs in your browser with nothing uploaded, no signup and no run limit.
