What AI Writing Assistant does

AI Writing Assistant adds a right-click option to any selected text on a webpage. Choose to fix grammar, rewrite the sentence, translate it, or find synonyms, and the extension sends that selection to Claude or GPT to generate a suggestion. It works inside text boxes, comment fields, and regular page content alike, so you don't need a separate app for quick text edits.

How it uses Claude or GPT

Instead of building its own language model, the extension routes your selected text to an existing AI model (Claude or GPT) to generate the edit, translation, or synonym list. This means the result quality tracks whichever model is processing the request, and your selected text is sent off the page to that model each time you use the feature.
