Google brings Gemini into legal. The AI headline is only half the story.
The Epona perspective, by Marcel Lang
"Google is not positioning legal AI as a chatbot sitting somewhere on the side."
Google’s announcement of Gemini Enterprise for Legal deserves attention. Not only because Google is entering the legal AI space with serious force, but because of the systems named around it: Microsoft 365, Word, Outlook, SharePoint, matter folders, permissions and institutional knowledge.
For Marcel Lang, CCO and co-founder at Epona, that is the part worth watching. Legal AI is moving straight towards the content lawyers use every day: documents, emails, matters, permissions and knowledge. The shiny AI layer gets the attention, but the quality of the foundation underneath will decide what legal teams can safely do with it.
What stood out in Google’s announcement?
“What stood out to me is that Google is not positioning legal AI as a chatbot sitting somewhere on the side. The announcement talks about workflows, documents, emails, matter folders, permissions and institutional knowledge. That is much closer to the way legal work happens.
And honestly, that makes the announcement more interesting. Legal AI will not live in a clean demo environment forever. It must work with the content lawyers use every day. That means matter files, email history, versions, permissions, metadata and internal know-how. Once AI moves into that environment, the foundation underneath becomes much harder to ignore.”
Why is Microsoft 365 mentioned?
“It shows where the legal AI discussion is heading. The model gets a lot of attention, of course, but access to governed legal content is becoming just as important. For Epona, the interesting angle is Microsoft 365. Many legal organisations already use Microsoft as their daily working environment. Word, Outlook, Teams and SharePoint are where a lot of legal work takes place. Epona365 builds on that foundation and adds the legal layer around matters, documents, emails, metadata and permissions.
So we should not read this as a story about one platform winning. We should read it as a sign that legal AI needs proper access to legal content, context and governance.”
What is the impact for firms using Microsoft 365?
“They should look beyond the AI tool itself. A firm can choose Copilot, Gemini, Claude or another legal AI solution. That choice is important, but the tool will still depend on the environment underneath. Where do documents and emails live? Are permissions clean? Can the system understand matter context? Which knowledge has been approved for reuse?
For firms already committed to Microsoft 365, SharePoint becomes a serious part of the legal technology discussion. Raw SharePoint alone is too generic for legal work. Legal teams need structure around clients, matters, emails, document types, confidentiality and review processes. Epona365 adds that legal layer to Microsoft 365 and SharePoint, so the environment supports daily legal work more directly.”
What should legal teams do?
“Start with the foundation, not the AI demo. Map where legal content lives. Review permissions. Check whether emails are properly filed. Assess metadata quality, identify which knowledge sources are trusted, and confirm ownership. Then look at the architecture. Is legal work mainly connected to Microsoft 365 from the outside, or is Microsoft 365 part of the actual legal work foundation?
For firms already committed to Microsoft, that question deserves serious attention. It affects governance, permissions, matter context and how AI can safely work with legal information.
A good next step is to pick one practical area to improve. It could be a practice area, a recurring document type or a set of clauses that lawyers ask for all the time. Start where better structure gives immediate value.
Legal AI will keep moving quickly. That is fine. Firms do not have to wait for the market to settle before organising their own content and knowledge. The organisations that prepare their foundation now will have more control over what AI can safely use later.”
AI needs context
Gemini, Copilot, Claude and specialist legal AI tools will all compete for attention. That will continue.
For law firms and corporate legal teams, the more practical question beneath the race is: can our document and knowledge environment support the way we want to use AI?
Epona’s view is simple. Better legal AI starts with better legal context. That context lives in documents, emails, matters, metadata, permissions and trusted knowledge. That is the layer legal organisations need to organise before AI becomes part of everyday work.
Curious where Epona fits in the legal AI ecosystem around Gemini, Copilot, Microsoft 365, DMS and KMS? Let’s talk about the foundation underneath it.
