Many times you remember a text you read on the internet, but you can't recall which website you read it on. You start trying to remember and search for the article on your usual pages, and after a few hours you might find it or, overwhelmed, give up. This problem has a simple solution, and it's called Memex, a Google Chrome and Firefox extension that lets you search web pages within your browsing history using a phrase.
Once installed (it's not in the Chrome store, but it is in the Mozilla store), it will start importing your browser history and indexes (though you can skip this step).
Once that's done, you're ready to search web pages by text. There are two methods: the first is to click on the platform icon at the top right of the browser and type the phrase in the dialog box.
The second option, and the most interesting for us, is to open a new browser tab and press the keyboard shortcut; "W + space bar" or "W + Tab". Then type the phrase in the address bar and press Enter. Results will appear on the right side of the browser.
Another noteworthy feature of the extension is the ability to disable the add-on for a certain time. You can do this by clicking on the extension's icon.
Now when you ask yourself Where did I read that phrase?, you'll simply turn to Memex, and in a few quick steps the answer will be available in your browser.
