AnswerVault vs Microsoft Copilot

Your team has Copilot. They still can't find the right policy.

Microsoft Copilot does what it's designed to do, it surfaces content a user can already access across Microsoft 365. But the way it does this creates three structural gaps that matter for regulated organisations, for teams that work with partners, and for any business whose documents don't live entirely inside M365.

This isn't a problem with Copilot. It's a consequence of how it's built.

Three things Copilot can't do

1. Answer from approved documents only

Copilot searches everything a user has permission to see, draft SOPs, superseded policies, personal OneDrive files, old SharePoint sites nobody cleaned up. For a compliance question, that's a problem. You want answers grounded in the current, approved version of the policy, not whatever surfaced first.

Microsoft has added controls here, and it is worth being precise about what they do. Restricted Content Discovery, part of SharePoint Advanced Management, hides named SharePoint sites from Copilot responses and org-wide search; Microsoft describes it as "a temporary governance control that gives organizations time to review and right-size access", it applies to sites rather than OneDrive, and it does not remove content from the index. Scoped agents can also be pointed at chosen sources. Both are deny-lists and readiness tooling: you name what to hide. Neither gives you an approved set that answers are confined to, which is the control a regulated approval process actually needs.

AnswerVault gives you governed knowledge bases: curated document sets where every answer is grounded in sources you've approved, with a full audit trail of what was asked and what was returned.

2. Serve contractors and partners without M365 licences

Microsoft Copilot is sold as an add-on to a per-user Microsoft 365 or Office 365 subscription. Anyone who does not hold one of those licensed seats cannot use it. If your contractors, delivery partners, auditors, or external stakeholders need answers from your documentation, they either email your team or wait. That delay is expensive, especially for pharma CROs running trials against your SOPs, legal clients needing policy clarifications, or citizens accessing government services.

AnswerVault extends to anyone outside your organisation through a web interface. No M365 licence, no Google Workspace seat, no access to your tenant. You choose which documents they can query; they see only those.

3. Search SharePoint, Google Drive, and Confluence with equal depth

Copilot is M365-native, and Microsoft 365 Copilot Search now reaches connected non-Microsoft sources as well. What Microsoft does not publish is any commitment that retrieval quality, indexing frequency and permission mapping for those sources match SharePoint, and the connector estate is configured and licensed separately. If your organisation has grown through acquisition, mixes tools across departments, or simply wasn't greenfield on Microsoft, that asymmetry is worth testing on your own content rather than assuming either way.

AnswerVault indexes SharePoint, Google Drive, and Confluence with equal depth, a single knowledge layer across all three, delivered through web chat, Teams, or Slack.

Side-by-side

AnswerVault Pro tier. Microsoft restructured Copilot licensing during 2026 into Copilot Chat (Basic), Microsoft 365 Copilot (Basic) and Microsoft 365 Copilot (Premium), alongside a Copilot Business SKU, a Microsoft 365 E7 plan that includes Copilot, and usage-based Copilot credits. Because the plan that applies depends on your existing Microsoft agreement, no single per-seat figure is quoted here. Check Microsoft's current pricing for your tenant.

When Copilot is still the right answer

If your organisation runs entirely on Microsoft 365, your users live in Outlook and Teams, and you want an assistant to summarise emails, draft documents, and help in the flow of Office work. Copilot is built for that. It's a productivity assistant.

AnswerVault is a governed knowledge layer. Different product, different purpose. Most organisations running Copilot still need somewhere to get a trustworthy answer from an approved policy, a way to give contractors access to documentation, and coverage of non-Microsoft sources. That's what AnswerVault does, and it sits alongside Copilot without replacing it.

Common objections

"We already have Copilot."

Good, we're not replacing it. Ask your team three questions. Can Copilot confine an answer to only your approved SOPs, rather than hiding selected sites from everything else? Can the people without a paid Microsoft 365 seat use it? And can it run the AI processing outside US corporate control? AnswerVault does those three things. Different product, different purpose.

"Won't this duplicate our Copilot spend?"

AnswerVault Pro is £7/user/month. If it saves your team the time it takes to find the right policy twice a week, it pays for itself. If it unlocks partner or contractor access you can't provide today, the ROI is not about internal time.

"We're waiting for Microsoft to close the gaps."

The gaps are structural. Licensing guest users, governing which documents Copilot can draw from, and treating non-Microsoft sources as first-class are all architectural decisions Microsoft has made deliberately. They're not on a roadmap, they're design choices.
