On September 17, 2026, Google announced that it is expanding its experimental AI agent CC (Japanese) so that families and households can use it. Up to six people can share information with a dedicated Google account for CC and have it organize their schedules and tasks. CC, which until now has supported an individual's day, will take on the job of pulling scattered messages from around the household into shared plans. But filling in a document is not the same as being able to sign it or make a purchase. Google's official FAQ also describes restrictions that affect the entire shared environment when members are changed or memories are deleted. Read together, Google's announcement and the official FAQ show what a family should decide before it starts sharing.
From one person's inbox to a shared household schedule
The new CC comes with a dedicated account that a family can designate as the place to share information. Each member can choose email senders, such as a school or an activity program, and pass those messages to CC. Google also envisions people forwarding individual emails or sharing photos of invitations in Google Chat.
CC's morning "Your Day Ahead" summary gathers the day's schedule, the tasks that need doing, and what CC finished the previous day. The design picks up events and tasks from shared messages and reflects them in the family calendar and task list. The aim is to ease the burden of having only the person who received a school notice remember its deadline.
Still, the feature does not open anyone's whole inbox to the family. According to Google's FAQ, each person sets which senders to share and can change them later. A person's main calendar is also not readable by CC by default; access requires separate sharing. CC's dedicated shared calendar is distinct from personal calendars.
Google says it introduced the earlier, individual version of CC in May of the same year as "Daily Brief" in the Gemini app. The household version works through existing tools such as Gmail and Chat to move shared work forward. Behind the scenes, each CC runs on an isolated cloud computer, using Antigravity, the agent execution platform, and Gemini models, according to Google.
The service is for people 18 or older in the United States, and a personal Google account is required. New users can join a waitlist, and upgrade invitations are going out to existing users in stages. The FAQ says migration is optional and gives no timeline for availability in Japan. Ars Technica also cites the age requirement in framing CC less as an AI that children use directly and more as an agent for parents managing busy households.
Filling in a PDF is not the same as signing or buying
CC can fill in school forms and activity registration PDFs, and it can help build shopping lists and meal plans. However, the FAQ explains that its PDF handling is "pre-filling": it completes editable fields for the user to review. It is designed to ask when information is missing, and it cannot handle encrypted or password-protected PDFs.
CC's permissions fall into three groups: organizing shared information, sending things outside the group with confirmation, and actions it cannot perform, such as signing and purchasing. Sorting the actions listed under "What CC can do for your family" and "What CC Cannot Do" in Google's official FAQ, as checked on September 19, 2026, by the conditions under which they run gives the following.
| Category | What CC handles | What remains with the user |
|---|---|---|
| Organizing and preparing shared information | Adds events from shared emails and pre-fills editable PDF fields | The PDF is for the user to review. Protected PDFs are not supported |
| External sending with confirmation | Sends documents, PDFs and Drive files outside the group | Explicit confirmation from a group member is required |
| Actions CC cannot perform | Completing purchases, entering credit card details, signing legal or school consent forms on someone's behalf | Allowing external sending does not enable CC to do these things |
This breakdown summarizes Google's published specifications; it is not a measurement of how often tasks succeed. Even if you hand off a registration form, the roles of checking the contents and completing the signature or payment remain with a person. In practice, the dividing line is that permission to send a document to a school and permission for AI to sign a consent form are not treated as the same action.
Rather than expecting CC to automate every family task, it is more consistent with the features Google describes to judge it by how much it reduces the work of rereading messages and copying them into a calendar, and the work of preparing documents. Beyond that, families need to decide who does the checking while they use it together, and what disappears when sharing ends.
Changing members and deleting memory affect the whole family
In CC, a member who has accepted an invitation cannot be removed from the group on their own. To change the group's makeup, the FAQ points to "Delete Group" in settings. This action deletes the current CC agent, along with the group's shared calendar, Chat space and task list, for everyone.
Each person's CC user account remains, however. Members do not have to rejoin the waitlist and can create a new agent with the same Gmail address. Keeping eligibility to use CC is not the same as keeping the shared workspace built so far.
Deleting memory has its own distinctions. Google explains that CC remembers household-wide preferences and associates them with individual details such as each person's food preferences, but deleting the original email in Gmail does not necessarily remove that information from CC's memory. The FAQ's explanation about stopping use says so plainly:
Simply deleting an email from Gmail does not delete it from CC's memory.
When a specific sender is removed from sharing settings, CC is described as deleting the related emails from its own inbox. To erase data completely, however, the FAQ points to "Delete Account" in CC settings. Revoking access to a sender and erasing all accumulated information are not the same thing.
"Delete Account" deletes that person's CC user account and related information; it does not mean deleting the Google account itself. If the person belongs to a group, that group's CC agent and shared spaces are deleted for everyone. The person who took the action must rejoin the waitlist to use CC again, while other members' CC user accounts are maintained. Emails CC sent in the past stay in inboxes unless each person deletes them manually. The official FAQ spells out these differences in what gets deleted.
An AI that organizes a family's plans concerns the whole family not only when sharing begins but also when someone stops using it. When deciding whether to invite CC, families should agree not just on the tasks they want to hand off, but on who shares what with whom, and how they will respond if the shared environment has to be rebuilt.
