📝 About this app
Replace words and phrases on websites with your own text rules in Safari. This Safari extension offers flexible matching options, rule ordering, and convenient tools for testing and backing up your settings.
Key Features:
• Create replacement rules with a source "Word" and target "Replacement".
• Use CS for case-sensitive matching and IN to match text inside larger words. For example, when the Word is her, turning IN off replaces only standalone her, while turning IN on also replaces her inside words such as other and there.
• Control priority with Rule Order (Top-Down or Bottom-Up) when multiple rules can match the same text.
• Set Default CS, Default IN, and Default RX so new rules start with your preferred options.
• Use Import / Export to back up your settings as JSON and restore them later.
• Preview how your current rules will transform text with the built-in Replacement Test.
Advanced Matching:
• Turn RX on if you want to use regular expressions in the Word field.
• Turn RX off to match symbols as plain text without escaping them.
• Example: to match [y/n], enter [y/n] with RX off, or \[y/n\] with RX on.
Notes:
• Works in Safari on websites where this extension is allowed.
• Spaces, punctuation, and surrounding characters affect how text is matched.
• Due to the wide variety of websites, compatibility with every site cannot be guaranteed.
• If needed, feel free to contact us before installing to check whether this extension works on a specific site.

★★★☆☆ Could use improvements
This extension is pretty good, but has plenty of room for improvement.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
