I'm curious if there's a way to create a floating icon, like the Grammarly button, that can be visible across different browser tabs without having users download a separate app or Chrome extension. After researching, it seems this might not be possible, and I'm considering the option of developing an extension or app instead. I'm new to software development and want to find the simplest way to validate my idea quickly.

You could use JavaScript to open multiple tabs, but you'd need iframes to access your target site. However, many websites block themselves from being embedded this way, so it may not work as you hope.
Unfortunately, websites can't access other open tabs for security reasons. Browsers take privacy seriously, which means a floating icon that appears across different tabs just isn't feasible without a dedicated extension or app.
