Get Google AI for Up to 83% Off by Sharing with Friends (Pro Plan from 202 JPY/Month)

I have thoroughly checked the terms and support regarding this, but please proceed at your own risk.

Google services have a system called "Family Groups," which allows you to share paid services with up to 5 family members (6 people including yourself). Looking into it further, I found that...

• Friends other than family members are also okay
• Available for Google AI as well
• Rate limits are individual
• Can be shared among 6 people including yourself

"Heartfelt family" (friends) are also fine, and what's more, the rate limits for Gemini and Antigravity are separate for each individual.

Plan	Monthly	Annual Contract	1 Person	2 People	3 People	4 People	5 People	6 People
Google AI Pro (Sale)	2,900	14,500	1,209	605	403	303	242	202
Google AI Pro	2,900	29,000	2,417	1,209	806	605	484	403
Google AI Ultra	36,400	-	36,400	18,200	12,134	9,100	7,280	6,067

Currently, the Pro plan is on sale for 14,500 yen per year (equivalent to 1,209 yen per month), and if shared among 6 people, it can be used for 202 yen per person per month.

• Google AI Plans and Pricing

Points to Note

• AI credits (required for image generation systems) are shared within the same pool
• You can only belong to one family group per year
• One person must act as the manager (parent) to pay upfront, requiring individual reimbursement
• The manager must turn on Google One sharing (required separately from adding members to the family group)
• Those who become members (children) may be subject to parental controls from the manager
• Therefore, it is safer to create a dedicated account rather than using your main account
• The Ultra plan does not have an annual contract and requires monthly settlement, which is a significant burden and not recommended

To avoid any trouble, it is safer to stick to using only the Pro annual contract.

Google Family Group Requirements

The official description is as follows, and factors such as blood relation, cohabitation, marital status, or shared finances are not required.

Being a "heartfelt family" (friends) is also not a problem.

To create a family group, you must be 18 or older (or the applicable age of consent in your country). Also, people you invite must have a Google account to join your family group. You can only be part of one family group at a time. You can only switch to a different family group once every 12 months.

Multiple Accounts are Apparently OK, But...

It is okay for an individual to have multiple Google accounts.

I confirmed this "persistently" with official support, and it seems that you can register multiple accounts as family members and switch between them.

However... considering Google's merciless account ban policy, I cannot highly recommend it.
