SwapText by João Sacramento

SwapText replaces words and phrases when you copy or cut text from supported webpages. Paste the corrected text into another browser tab or desktop application.

Create your own replacement rules for recurring typos, preferred terminology, or consistent spelling.

Features:
• Whole-word and case-sensitive matching.
• Preserve capitalization.
• Optional regular expressions.
• Rules restricted to specific domains.
• Preserve formatting such as bold, italics, and links.
• Live preview to test your rules.
• JSON import and export.
• Quickly pause replacements.

Your rules and settings stay in your browser. No account is required, and the extension sends no text, rules, or browsing data to a server.

Firefox-protected pages and some custom editors are not supported. With formatting preservation enabled, phrases spanning separate formatting elements may remain unchanged.
