Is Your Family Paying for Two AI Assistants That Do the Same Thing?

There's a new line on the family budget that didn't exist two years ago: AI subscriptions. Chances are, one person in your household is paying £17–£20 a month for ChatGPT Plus, another signed up for Claude Pro after a recommendation, and someone else gets Gemini bundled into a Google One plan they barely remember buying. Add those up and you could be spending £50–£60 a month on AI chatbots — for largely the same core capability.

According to Ramp's spending data, 79% of people who pay for OpenAI's ChatGPT also pay for Anthropic's Claude. That's a lot of duplicate spending in a category that barely existed in most household budgets three years ago.

How the AI Subscription Pile-Up Happens

It's not that families are being careless — it's that AI tools spread through households in different directions at the same time.

A teenager starts using Claude Pro for essays. A parent upgrades to ChatGPT Plus for work. Another family member has Google AI Pro bundled into their Google One storage plan. Nobody compares notes, because it feels like a personal tool rather than a family subscription. So nobody asks: "Wait, are we paying for this twice?"

The standard price for a mainstream AI assistant in 2026 sits at £17–£20 a month. ChatGPT Plus costs $20/month, Claude Pro is $17–$20/month depending on your plan, and Google AI Pro comes in at $19.99/month. If two family members each hold one of these, that's already £35–£40 a month on AI alone.

What's Actually Different Between Them?

Honestly, for most everyday tasks — summarising a document, drafting an email, helping with homework, explaining a concept — ChatGPT, Claude, and Gemini are all excellent. The differences matter more at the edges:

• Claude is particularly strong on long documents and nuanced writing tasks
• ChatGPT has the deepest integration with third-party tools and plugins
• Gemini earns its keep if your family is deep into Google Workspace — Docs, Gmail, Drive

For general day-to-day use, one good AI subscription covers most of what a family needs. The case for having two at once is thin unless someone has a specific professional need (a developer who relies on ChatGPT's code interpreter and a writer who prefers Claude's voice, for example).

The Audit: What Is Your Family Actually Paying?

Before your next billing cycle, spend ten minutes tracking down what's active. Check these spots:

1. Your bank or credit card statement — filter for "OpenAI", "Anthropic", "Google One", "Microsoft", "Perplexity"
2. iPhone: Settings → your name → Subscriptions
3. Android: Play Store → Profile → Payments & Subscriptions
4. Your email inbox — search for receipts from any AI service

SubManager's spending breakdown makes this easy if you've connected your accounts — the Analytics tab will surface any recurring AI charges so you can see the total at a glance, not chase them down one card at a time.

What to Do Once You've Found the Overlap

Option 1: Pick one and cancel the rest. For most families, ChatGPT Plus or Claude Pro will handle 95% of everyday tasks. Pick the one that most people in the household are actually logging into, cancel the others, and pocket the difference.

Option 2: Use the free tiers more deliberately. All three major AI assistants have capable free tiers. If your usage is light — the occasional help with a letter, some homework support — you may not need a paid subscription at all. The free version of ChatGPT, Claude, or Gemini handles routine tasks well. Downgrade, try the free tier for a month, and only upgrade if you genuinely hit limits.

Option 3: Consider a multi-model plan. Services like Krater offer access to multiple AI models (GPT, Claude, Gemini and others) under a single subscription, with family sharing for around $119/month for up to five people. That only makes sense if multiple family members are heavy users with genuine needs for different models — but it's worth knowing the option exists.

A Simple Rule for the Future

AI subscriptions have the same creep problem as streaming: each one feels small, but they compound. Set a household rule now: before anyone adds an AI tool paid subscription, check what the family already has active. A five-second message in the family group chat saves a recurring charge that nobody cancels for months.

SubManager can send you a renewal alert before any AI subscription charges — so at minimum, you see the cost arriving before it hits, rather than noticing it three months later on a bank statement.

The honest summary: pick one AI assistant, share it where the service allows, and revisit the decision every six months. You'll do the same work, spend £20 less each month, and put that £240 a year somewhere that actually matters to your family.
