Google has launched a new journaling app called Pixel Journal, introduced at the Pixel 10 launch event in August 2025. Pixel Journal uses on-device AI, specifically the Gemini Nano models running on the Pixel 10’s Tensor G5 chip, to provide writing prompts that help users fill out journal entries. These prompts are personalized based on memories, past entries, and user goals to assist in processing thoughts and maintaining journaling habits.
The app allows users to add photos, locations, activities, and mood entries to their journal. It also provides insights about writing patterns such as when users commonly write, the longest entry by word count in a given period, and the total number of entries per week or month. For privacy, Pixel Journal supports locking the app with a PIN to keep entries secure and all data processing is done offline on the device.
Currently, Pixel Journal is available exclusively for the Pixel 10 series, with potential plans to expand support to older Pixel devices in the future. The app is currently offered in English only.
This launch positions Google’s Pixel Journal as a private and AI-enhanced journaling tool, comparable to Apple’s Journal app introduced in 2023 but with a unique approach focusing on on-device AI and data privacy.
