Google’s Gemini is getting a feature called “notebooks” to help you organize things about certain topics in a single place while using the AI chatbot, the company announced on Wednesday. You can pull in things like files, past conversations, and custom instructions into notebooks that Gemini can then use as context while you’re talking with it.

Notebooks sound a lot like ChatGPT’s Projects feature, which launched in 2024 and similarly lets users store things about a certain topic in one spot. Google says to “think of notebooks as personal knowledge bases shared across Google products, starting in Gemini.” Gemini’s Notebooks also sync with Google’s NotebookLM AI research tool, meaning sources you add while using one of the apps will show up in both.

Gemini’s notebooks are rolling out this week on the web for subscribers of Google’s AI Ultra, Pro, and Plus plans, according to Google. The feature will come to mobile and to free users in the “coming weeks.”
