00vs Microsoft Copilot

Copilot lives inside Microsoft.
We work everywhere else too.

Microsoft 365 Copilot is $30/user/month on top of an M365 license, locked to Office. Perpetual Core is $99/month, portable across Google Workspace, Notion, Slack, and custom apps. Multi-model routing, persistent org memory, 15 industry advisors, and an install path. Here's when each makes sense.

01Feature matrix
CapabilityPerpetual CoreM365 Copilot
Multi-model routing (Claude + GPT-4o + Gemini)

Copilot is locked to OpenAI via Microsoft. PC routes across providers based on task.

Persistent organizational memory across users

Copilot uses Microsoft Graph context within M365. PC has explicit org-wide memory across all sources.

15 industry-specific AI advisors pre-built

Copilot has Copilot Studio for custom agents but no pre-built industry advisors.

Works without a Microsoft 365 license

Copilot requires a paid M365 Business Standard or Enterprise license ($12.50-$57/user/mo) on top of the $30 Copilot license.

Native integration with Office (Word, Excel, PowerPoint, Outlook)

Copilot lives inside Office apps. PC integrates with Google Workspace; Office connectors are on roadmap.

Gmail + Google Calendar integration

PC integrates with Google Workspace natively. Copilot is Outlook-only.

Document RAG on full corpus (pgvector)

Copilot pulls from Microsoft Graph (Office files, SharePoint). PC indexes any source via pgvector.

BYOK / bring your own API key

Copilot uses Microsoft's hosted OpenAI deployment. PC supports BYOK on Pro tier.

Production engagement option ($75K+ install)

Microsoft offers FastTrack + partner network. PC offers Atlas Discovery → direct engagement.

10–15% of revenue funds nonprofit mission work

PC partially funds the Institute for Human Advancement.

501(c)(3) nonprofit discount

Microsoft has nonprofit licensing programs. PC ships 30% off Vellum for verified 501(c)(3)s.

Portable — not locked to one productivity ecosystem

PC works with Google Workspace, Notion, Slack, and on its own. Copilot only inside Microsoft.

02When to use what

Stay on Microsoft Copilot if…

Your team lives inside M365 — Word, Excel, PowerPoint, Outlook, Teams. Most of your AI work is “help me draft this email,” “summarize this meeting,” “explain this Excel formula.” You already pay for M365 so the marginal cost is just the Copilot license. And you prefer one vendor for both productivity + AI. That's a real preference and Copilot is solid at it.

Add or switch to Perpetual Core if…

Your stack is mixed — Google Workspace, Notion, Slack, custom apps, Office on the side. Or you want multi-model routing (not just OpenAI via Microsoft). Or you don't want vendor lock-in. Or you want the 15 industry advisors + the install-engagement path that Copilot doesn't offer.

Run both, honestly.

Many enterprises run Copilot inside Office for document work and add Perpetual Core as the cross-tool org memory layer (since Copilot only sees Microsoft sources). Pro tier is $99/month with BYOK — bring your existing OpenAI API key and route through your enterprise contract.

03Common questions
We're a Microsoft shop. Why add Perpetual Core?
If 100% of your team lives inside Word, Excel, Outlook, and PowerPoint — and that's where AI should meet them — stay on Copilot. PC is for orgs that have a mixed stack (Google Workspace, Notion, Slack, custom apps), want multi-model routing, or want one AI layer that isn't locked to one productivity ecosystem. Many enterprises run both: Copilot inside Office for document work, PC for the cross-tool org memory layer.
What does Copilot actually cost us, total?
Microsoft 365 Copilot is $30/user/month — but only on top of a qualifying M365 license. For a 50-person team on M365 Business Standard ($12.50/user/mo), the all-in cost is $42.50/user × 50 = $2,125/mo. PC Teams pricing for 50 seats is typically $500-$1,000/mo. If you already pay for M365, Copilot is incremental. If you don't, switching ecosystems just for Copilot is expensive.
Will Copilot replace our Outlook, Word, and Teams?
No, Copilot lives inside them. It's an AI assistant layered on the Microsoft apps you already use. If your team is happy in M365, that's a strength. If your team uses Google Workspace, Notion, Slack, and other tools too, Copilot only sees the Microsoft side — which is where PC's multi-source memory layer becomes useful.
How does data residency work compared to Microsoft Copilot?
Copilot keeps data inside your M365 tenant in Microsoft Azure regions you select. PC stores data in Supabase (US-based by default; EU residency available on Teams tier) with row-level security per workspace. Both are SOC 2 — pick based on whether your security policy already approves Microsoft Azure vs Supabase/AWS.
What about Copilot Studio — can we build custom agents like in PC?
Copilot Studio lets you build custom agents that live inside the Microsoft ecosystem. PC's advisor builder lets you build agents that live in PC and access your full document corpus across any source. Different scopes: Copilot Studio agents are great inside M365; PC agents are great across your whole stack. If you'd rather not be locked into one ecosystem, PC.
