Google has reportedly published a new app called "Look up" for Googlebook on the Google Play Store.
According to 9to5Google, while the initial listing featured the app's icon, screenshots, and descriptions, they have all since been replaced with placeholders, making it impossible to check the details at the time of writing.
What is the New "Look up" App?
The newly discovered "Look up" app, carrying the package name com.google.android.desktop.contextualtools, is clearly designed for Googlebook (Android Desktop).
Look up lets you "highlight a concept you want to explore, a new word, a trip destination, and more." This opens a floating window, with screenshots showing a dictionary, flight tracker, "Overview," and translator.



The "Ask a follow-up question" field at the bottom provides a conversational Gemini experience. The Play Store icon is a pair of glasses badged by the Gemini spark. Google explains that "Look up will use publicly available information from the relevant Google service (e.g. Search, Maps, Flights) to provide the best response in a helpful format."
This functionality behaves quite similarly to the native "Look up" feature found on macOS.
How It Differs from "Help me read" and Gemini in Chrome
While the Chromebook Plus "Help me read" feature offers Gemini-powered "Summarize," "Simplify," and Q&A options, its capabilities are strictly confined to the content visible on the screen. In contrast, "Look up" stands out by leveraging a broader scope of public information across various Google services.
Additionally, unlike Gemini in Chrome, which targets entire web pages in the browser, "Look up" allows users to focus strictly on specific selected words or texts. This offers a major advantage for users seeking quick, context-specific insights.
The Third App Tailored for Googlebook
To date, Google has not officially announced any features or standalone apps corresponding to "Look up."
However, Google has previously released Googlebook-specific applications on the Play Store, such as Desktop Camera and Magic Pointer. Given this track record, this newly spotted "Look up" app is highly likely to be officially unveiled alongside the upcoming Googlebook launch.
