Sumsum

Read more news without getting lost in every detail.

SumSum turns long news articles into clear, concise summaries using AI that runs directly on your Android device. Share an article from your browser or news app, and SumSum brings the key points to you in a convenient overlay—without interrupting your reading flow.

SUMMARIZE FROM ALMOST ANY NEWS APP

Found an interesting article but don’t have time to read the whole thing? Use Android’s Share menu and send it to SumSum. The app extracts the important information and presents an easy-to-read summary right over the article you were viewing.

PRIVATE, ON-DEVICE AI

Your summaries are generated locally on your phone. SumSum uses the best compatible on-device model available, including Gemini Nano through Android’s summarization or prompt APIs on supported devices. On other compatible devices, SumSum can use Gemma or another locally running model.

Because summarization happens on your device, article content does not need to be sent to a remote AI service for processing.

SumSum automatically keeps a history of your summarized articles, making it easy to return to an important story or revisit the key points later.
