I spent some time looking at this. It's apparently a new feature being rolled out in Chrome.
The following flag enables the "Help me write" feature, which is a handy AI assistant for improving your written content.
chrome://flags/#help-me-with-this-page refers to a specific, experimental flag within the Google Chrome browser that controls the "Help me write" feature, which provides AI-powered writing assistance directly in the browser. To use it, type the full URL into your Chrome address bar, press Enter, and then adjust the settings for the "Help me write" flag, such as choosing between "Polish," "Elaborate," or "Formalize" options to refine your text in various contexts.
I couldn't tell you if it can be disabled via this flag because the issue/feature isn't showing for me.
Another flag chrome://flags/#search-side-panel A broader flag that may be available and relevant (removes other AI side‑panel prompts too)
