Google wants to free users from manually creating tabs, so the Chromium team is currently testing a feature called ” Tab groups Auto Create”, which when enabled, group tabs in Chrome will be created automatically.

The tab groups feature is available to everyone in Chrome 85 stable release.
The feature is available by default, but again, the user has to do the work themselves and create the group tabs for each different topic.
But what would it be like if Chrome did the entire process on its own without the user's help? Google is currently conducting relevant tests.

The "automatic tab creation" feature is available with a flag in the latest Chrome Canary 87.0.4266.0 for Windows, Mac, Linux , and Chrome OS and can be enabled.
Enable the automatic tab grouping feature in Chrome
- Launch the Chrome browser
- Visit the chrome://flags page
- Search for the ”Tab Groups Auto Create”
- Click the dropdown arrow and select ”Enabled”
- Restart the browser
If you open a link from the same domain in different tabs, Chrome will automatically group them. See the detailed video from Techdows.
The Chromium team committed to two things: to “add about:flags entry” and “automatically create a new group when users open a new tab with the same domain as their home tab.”
In case you are using the stable version of Chrome, you can make group tabs collapsible and expandable by enabling the flag ” Tab Groups collapse” on the chrome://flags page.
Google is also testing the “freezing” feature of grouped tabs to save more resources.
