Microsoft 365 Family Gives AI to One Person. Here Is What That Means for Your Family.
Saturday morning. Three people need a document at the same time.
Your partner is on the phone with the insurance company and needs the policy number from a PDF buried somewhere in OneDrive. Your teenager has a university application open and needs their vaccination record. You are staring at a CRA notice and need last year's notice of assessment to figure out what changed.
Three people. Three urgent documents. One family Microsoft 365 subscription. You might assume the AI assistant can help all of you at once. It cannot.
What Copilot actually includes in Microsoft 365 Family
Microsoft 365 Family costs $139.99 per year (or $13.99 per month in Canada) and covers up to six people. Everyone gets Word, Excel, PowerPoint, Outlook, and 1 TB of OneDrive storage. It is a genuinely good deal for productivity software.
In January 2025, Microsoft added Copilot to the Family plan. But the AI access is not shared equally. Copilot is available to the primary account holder only. The other five family members do not get it.
If your partner or your teenager wants to use Copilot to search their own files, summarize a document, or draft an email, they need a separate Copilot Pro subscription at $26.99 per month each.
The cost math for a family of four
M365 Family plan: $139.99/yr | Archevi Family plan: $180/yr ($15/mo)
Copilot for account holder: included | AI for all members: included
Copilot Pro for 3 additional members: $971.64/yr ($26.99/mo x 3 x 12) | No per-member AI fees
Total for family of 4 with AI: ~$1,112/yr | Total for family of 4 with AI: $180/yr
Per-person AI cost: $278/yr for account holder, $324/yr for each additional | Per-person AI cost: $45/yr per member
That is not a typo. Giving every member of a four-person family access to AI-powered document help through Microsoft costs roughly six times what Archevi charges for the same household.
What Archevi does differently
Archevi is built for families, not for individuals who happen to share a subscription. Every member of a Family plan gets full AI-powered document search and retrieval. There is no primary account holder who gets special treatment.
- Every member gets AI. Upload a document, ask a question, get a cited answer pointing to the exact page. No one is locked out.
- Boundary anonymization. Before any AI model processes your document, personal identifiers -- names, SINs, account numbers -- are stripped and replaced with anonymous tokens. The AI answers your question without ever seeing who the document belongs to.
- Canadian data residency. Your documents stay on encrypted servers in Toronto, Canada. They are subject to PIPEDA, not the US CLOUD Act.
- Purpose-built for family records. Tax returns, insurance policies, wills, medical records, vaccination certificates. Archevi is designed for the documents families actually need to find and protect.
Be honest: Microsoft 365 is excellent at what it does
This is not a hit piece. Microsoft 365 is the best productivity suite available. Word, Excel, and PowerPoint are industry standards for good reason. OneDrive works seamlessly across Windows, Mac, iOS, and Android. If your family creates, edits, and collaborates on documents regularly, M365 Family is worth every dollar.
Copilot inside Office apps is genuinely useful for drafting, summarizing, and analyzing content within Word and Excel. For the account holder who has access, it saves real time.
The limitation is specific: Copilot helps you work with documents you already have open. It is not designed to search across years of family records, find a specific clause in an insurance policy you uploaded two years ago, or remind you that your passport expires next month.
Archevi is not replacing Microsoft Office. Many of our users keep their M365 Family subscription for Word, Excel, and email, and use Archevi as the searchable, AI-powered vault for their important family documents. The two products solve different problems.
What this means for your family's documents
The question is not whether Microsoft 365 is good software. It is. The question is whether paying $1,100 per year to give every family member AI access to their files is the right approach when the AI was designed for productivity tasks, not family document management.
Family documents have different requirements than work documents. They contain Social Insurance Numbers, medical histories, legal designations, and financial details that demand stronger privacy protections. They need to be findable by any family member, not just the primary account holder. And they need to stay in Canada if that is where your family lives.
If you are uploading tax documents to sort out your 2025 return, now is the time to decide where those files live. Once your notice of assessment, T4 slips, and RRSP contribution receipts are scattered across email attachments and cloud drives, finding them next year becomes its own project. Upload them to Archevi now and they are searchable, protected, and ready when you need them.
Try it with your own documents
Archevi has a permanent free plan, no credit card required. Upload a tax return, an insurance policy, or a vaccination record. Ask a question about it. See how fast you get an answer -- and notice that your personal details never leave Canada.
If you decide it is not for you, cancel anytime. No contracts, no cancellation fees, no fine print.
