About Replace Prefix
Replace Prefix looks for a given prefix on each line and replaces it — only when the line actually starts with it.
It is useful for changing list markers, indent levels, or path prefixes.
FAQ
Is my text sent to a server?
No. Replace Prefix runs entirely in your browser — the text you enter never leaves your device.
