Every SEO and marketer ends up managing large lists of keywords, URLs, or text, and knowing how to quickly keep only lines that begin with a specific character or text string is one of those small, repetitive tasks that quietly eats up time when it's done by hand.
What This Tool Actually Does
Keep Lines Starting With keeps only lines that begin with a specific character or text string, applied instantly to an entire pasted list at once.
Isolating URLs From One Directory
Keeping only lines starting with a specific path quickly isolates one section of a larger URL export for focused review.
Why Doing This by Hand Doesn't Scale
Handling this manually is manageable for a handful of lines, but the moment a list grows to hundreds or thousands of entries, manual editing becomes slow and genuinely error-prone. A dedicated tool applies the same rule consistently across the entire list in seconds.
Next step: Use the free Keep Lines Starting With tool from SeoWolf's Notepad to keep only lines that begin with a specific character or text string directly in your browser, with no login or software install required.
