Readefine

What is 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.
MaskMyPrompt

What is MaskMyPrompt?
MaskMyPrompt lets you anonymize ChatGPT prompts by swapping real names for fake ones before you paste anything into the model. It works as a lightweight paraphraser focused on privacy: scan your text for people, organizations, and locations, then replace them with made-up stand-ins so confidential details never reach ChatGPT. Everything runs locally in your browser tab using Transformers.js, and the site states your prompt data is never saved or sent to any server.
Most privacy wrappers route text through a backend API, which means you still trust a third party with the raw input. MaskMyPrompt keeps the entire masking step on your device, which is a narrower but more private approach. The trade-off is a single-page utility with no team features, no pricing tiers, and no integrations beyond copy-paste into ChatGPT.
It fits developers, researchers, and anyone drafting ChatGPT prompts that mention real people or companies. Mike Ushakov built the tool, and you can reach him via email or Twitter for bug reports and feature requests.
