自動補完・リサーチ・Chrome拡張を備えたAIライティングアシスタント

Messaging Assistant 🚀 is a small Chrome extension that adds two AI shortcuts to your browser: one that generates a reply inside a WhatsApp conversation, and one that rewrites whatever text you have selected so it reads better and more concisely. There is no dashboard to learn and no account to set up — you install it, and the shortcuts work on the pages you already use.

Press Ctrl+Q inside a WhatsApp Web conversation to have an AI-drafted reply appear, ready to send or edit.
Turn on auto-generation in the extension settings if you want replies suggested without pressing the shortcut each time.
Highlight any text and press Alt+R, or right-click and choose 'Rewrite Selected Text', to get a clearer, more concise version.
The developer states the extension has no server of its own and communicates straight with the OpenAI API, with no data stored or read.
Two shortcuts and one context-menu item cover the whole feature set, so there is no interface to learn.
