Does it replace all matches at once?

Yes. Every occurrence of the find string in the input is replaced in a single pass. The output area is regenerated live as you type, and the match counter shows exactly how many replacements happened — your verification receipt before copying.

Does it support regular expressions?

No. This tool matches plain strings only — no \b boundaries, no .* wildcards, no capture groups. If you need regex, paste your source into a code editor (VS Code, Sublime, JetBrains) which all support regex find-and-replace, or use a regex-aware online tool. We deliberately keep this one fast and predictable.

What does Case Sensitive actually do?

When Case Sensitive is OFF, the find string "Cat" matches Cat, cat, CAT, and CaT. When ON, "Cat" only matches the exact sequence Cat — useful for code, environment variable keys, file paths, and any context where capitalization carries meaning. The replacement string is inserted verbatim regardless of the toggle.

Can I use it on multiline content like CSV or pasted code?

Yes. Line breaks are preserved and the tool searches across the entire pasted content as one string. CSV rows, multi-line code, prose paragraphs, and log dumps all work. Empty lines and trailing whitespace are kept exactly as you pasted them.

Is my text uploaded or stored anywhere?

No. Everything runs locally in your browser using JavaScript's built-in string replacement. No server call, no analytics on your content, no logs. You can paste secrets, PII, or draft contracts safely — when you close the tab, the text is gone.

Can I undo a replacement?

There is no undo button — the output is recomputed from your current input and find/replace fields. To "undo", swap the find and replace values and run again. As a habit, keep the original input in a separate scratch area or temporary file until you're sure the result is correct.

Why does my replacement seem to over-match?

Plain-string matching has no word boundaries, so "the" matches inside "there", "them", and "breathe". Either include surrounding spaces in your find string (" the ") or use Case Sensitive to narrow the match. If you need precise word-only replacements, regex in a code editor is the right tool.

Does the tool work offline?

After the page loads, yes — all processing happens client-side. Future loads still need network access to fetch the page itself (this isn't a PWA), but the replacement logic uses zero network.
