AI Text Improver

AI Text Improver is a lightweight Chrome extension built around a single gesture: highlight text, click, and get a better version of it. It is positioned primarily as an email assistant — the listing leads with Gmail and Outlook — but the selection-based workflow means it also works on form fields, documents and comment boxes anywhere in the browser.

The extension is powered by GPT-4o from OpenAI, which handles the rewriting; the extension itself is a slim 16.72 KiB wrapper that adds a button and a diff-style insertion option to the page. You can choose whether the improved text replaces what you selected or is added below it, which makes it easy to compare your original phrasing against the polished version before committing.

The developer ships one small, focused tool rather than a full writing suite: there is no account, no dashboard, no team plan and no cloud document store. That keeps the scope clear, and it also means the quality of the output depends almost entirely on the underlying model plus your selection. It is best suited to people who write a lot of short professional messages and want a fast second pass before sending.
