How to Share ChatGPT Plus or Claude Pro With Family (2026)

To share ChatGPT Plus or Claude Pro with family, don't share the login. As of October 2026 we found no family plan for either one, and Anthropic's consumer terms say you may not share your account login or make your account available to anyone else. The workable options are separate accounts for everyone, a two-seat team plan, or one workspace where you pay for a seat per person and each person keeps their own login, chats and credits.

The third option is the cheap one if people in your house want both GPT and Claude. Zemith's workspace seats cost $15.99 per person per month on Plus, so two people pay $31.98 where two people with ChatGPT Plus and Claude Pro each would pay about $80. The rest of this post covers what each option costs, why a shared login goes wrong, and how to set up the seats.

The steps in short

1. Decide who needs what. One person doing heavy research and three people asking for recipes and homework help don't need the same plan.
2. Give everyone their own login. Shared logins mix up chat history and memory, and the account owner answers for everything done on it.
3. Compare the legitimate ways to split the bill using the table below.
4. If you want GPT and Claude for each person, create a workspace in Zemith, buy one seat per person and invite them by email.
5. Agree the house rules once: who pays, what happens when someone leaves, and who sees what.

Why can't you just share one ChatGPT Plus or Claude Pro login?

For Claude, the answer is written down. Section 2 of Anthropic's consumer terms says: "You may not share your Account login information, Anthropic API key, or Account credentials with anyone else." Claude's pricing page lists Free, Pro, Max and Team plans, and no family plan.

For ChatGPT, we found no family plan either. OpenAI's own community forum has open requests for one, including one from people who want four household members on one Plus subscription. OpenAI's terms page blocked our automated check, so read the current terms yourself before you share a ChatGPT login.

Even where nobody objects, a shared login is awkward:

• Everyone sees everyone's chat history, and personal memory features learn from all of you at once.
• People report chats failing to load or stalling when two devices use the same account at the same time (OpenAI forum thread).
• The person whose name is on the account is responsible for everything anyone types into it.

What are the legitimate ways to split the cost?

The ChatGPT Plus price is a third-party figure (layer3labs, October 1, 2026); OpenAI's pricing page localizes prices and blocked our check. The Business and Team prices come from OpenAI's Business billing article and Claude's pricing page. Our earlier post on ChatGPT Business alternatives for small teams goes deeper on the team plans.

If your household already lives in Google's world and Gemini is enough, Google's family sharing is the one first-party way to share an AI plan. If anyone wants Claude or GPT, it won't cover them.

What does a household pay for ChatGPT and Claude per year?

Here are yearly totals at list prices, billed monthly except where the last column says yearly, for two people and four people who each want both ChatGPT Plus and Claude Pro.

The yearly Zemith plan is $179.88 per seat ($14.99 a month). Two people save about $600 a year over buying both subscriptions for each person, and four people save about $1,200. The comparison isn't one to one. A Zemith Plus seat gives you GPT 6 Luna and Claude 5.5 Sonnet, not the full ChatGPT app or Anthropic's own Claude app with its limits, and the top models (GPT 6.1 Sol, Claude 5.5 Opus, Gemini 4 Argon) need a Professional seat at $29.99 a month. For homework, writing, planning and everyday questions, most people won't miss the difference.

How do you give each person their own seat in Zemith?

Zemith workspaces are built for teams, but nothing stops a household from using one. The owner pays, and each person you add gets their own credit allowance and sees only their own chats. You need a Plus or Professional plan yourself, and you set the seats up on the web.

1. Create the workspace. Open the workspace menu, choose New workspace, name it (for example "Home"), and pick Continue to plans. A team workspace needs a paid owner seat, so you choose your own plan here.
2. Open the Workspace tab. Go to your profile and open Workspace. As the owner you'll see Additional member seats.
3. Choose Add member. Pick the Plan for that person (Plus or Professional) and type their email under Member email. You can mix plans: Plus for most of the family, Professional for the one person who does heavy work.
4. Review the purchase. Choose Review purchase and confirm. Zemith shows the charge before it sends anything, and your own plan isn't part of this purchase.
5. They accept. Someone who already has a Zemith account is added straight away. A new user gets an email invitation that is valid for seven days. You can Resend or Revoke it from the same list.

Each seat has its own credits: 1.5 million a month on Plus, so one person's image session doesn't drain another person's allowance. Seats are billed to the workspace payment method, and you can cancel the seat subscription from the same tab. If someone leaves, removing them takes their plan and credits away immediately, and the paid seat stays with the workspace so you can give it to someone else.

Can the owner read everyone else's chats?

Not through the member list. The members screen shows names, roles and plans. In Zemith's access rules (checked October 2026), a chat inside a workspace can be read by the person who started it and by anyone they explicitly invite to that chat, not by the workspace owner. That's an access rule, not a privacy certification, so keep truly sensitive material out of any online chat tool.

Honest caveats

• It isn't the same product as ChatGPT Plus or Claude Pro. You won't get Anthropic's Claude Code or OpenAI's Codex, and Zemith's chat isn't the ChatGPT app. If one family member lives inside the ChatGPT app, they should keep it.
• It's a team workspace, not a family product. There's no SSO or admin tooling like the big team plans, and everyone you add manages their own account.
• Seats are bought on the web. The owner buys and manages them there.
• Check each seat is worth it. A seat nobody opens still costs $15.99. Start with the two people who'd use it most.

Setting house rules once

A shared plan goes wrong over money and leavers, not technology. Settle these in five minutes:

• Who pays, and does everyone chip in? A monthly transfer of $15.99 per person is simple.
• What happens when someone moves out or stops using it? Remove the seat and reassign it.
• Anything personal (health, money, job hunting) stays in your own chats, and nobody asks to see them.
• Upgrades: a Professional seat is $29.99, so the person who wants it covers the $14 difference.

The bottom line

Don't share one login. Give each person an account of their own, and if two or more people want both GPT and Claude, a Zemith workspace is the cheapest way to do it: $15.99 per person on Plus, one bill, separate chats. Keep ChatGPT Plus or Claude Pro for the one person who truly needs the vendor's own app.

How we compared

We compared published pricing and documentation in October 2026: Anthropic's consumer terms and Claude's pricing page, OpenAI's Business billing article and community forum, Google's AI plans page, and Zemith's seat flow, plan prices and access rules in its source code. OpenAI's pricing and terms pages blocked automated checks, so the ChatGPT Plus price is a third-party figure and we couldn't read OpenAI's terms.
