While many are still sore about Google killing off Google Reader, the company is busy pursuing other potential products. An Evernote-like service from Google called Google Keep has been spotted in the wild.
1E100 appears to be the first to have mentioned the product in a Google+ update. They found Google notes in the code of Google Drive pointing to an notes-like icon, then found a new Google Account Service named “Portal," which when signed in, added a new service called "Google Keep," though it has since been removed.
Android Police points to this hint about the service in an official Google+ post back in July. Notice the "Add to Google Keep" link in the second image.
When you're on the go, Instant Preview on mobile can help you find what you're looking for faster. Say that you're at the grocery store, searching for [cheese party ideas] and want to find a website that has photographs, as well as written tips, to give you inspiration. On the search results page, you can tap on the magnifying glass next to any search result to see a webpage preview. When you see a preview that you'd like to explore more, simply tap on it and you'll be taken directly to the website. This feature is available for Android (2.2+) and iOS (4.0+) devices across 38 languages.
Android Police was able to grab a screen cap of the desktop version of Google Keep before it was taken down (reports indicate an Android app is on the table as well).
Of course just because Google is working on something does not mean it will come to fruition. The company is constantly experimenting with and testing new ideas, but don't be surprised if Google makes an announcement about this sometime in the near future.
