Extreme AutoComplete is a useful extension that automatically completes sentences you have previously typed before so you no longer have to type all of the words again the next time you search for it. And since it saves the data locally, you don't have to worry about your data being sent to other sites.

Once installed on your browser, this extension is very easy to use. It even has Hotkeys, which will save you more time.

More information:

The local database saves the data of all the users who are using this extension. It will remember the old sentences that the user typed and it will provide those sentences as autocomplete options. You will find all the old sentences on the main panel.

The extension will work on Gmail, WhatsApp, and all the social networks.
