Readefine
Readefine is a Chrome extension that rewords text on live webpages as you browse. It pairs a dictionary engine for instant word and phrase swaps with optional AI modes that simplify, summarize, translate, or restyle copy in place. You can load community-built dictionaries or write your own rules for jargon, units, and terminology.
Most paraphraser tools ask you to paste text into a separate editor. Readefine works directly on the page you are reading, which helps when you are scanning news, docs, or forums and want the site itself rewritten without copy-pasting. The trade-off is it is Chrome-only and depends on the extension staying active in your browser session.
ESL readers, students, and parents who want simpler language on everyday sites are the core audience. Researchers and professionals can use tone presets or custom AI prompts on a paid plan to reshape dense industry copy while they read.
