How Sevrelcompares.
Written to be useful during an evaluation rather than to win an argument. Where a competitor is genuinely better for your situation, it says so.
Start with what is no longer true
AI comparison pages tend to age badly, and this one used to. It is worth stating plainly: general assistants can reach your document repository now. ChatGPT and Claude both support connectors, including the Model Context Protocol, and Egnyte publishes an MCP server. If someone tells you a general assistant can only read files you paste into a chat window, they are describing 2024.
So “we can read your documents and they cannot” is not the argument. The argument is that reading a document is the easy part. What a commercial real estate organization needs is everything around the answer — who may ask, what was used to answer, whether it was recorded, whether it happens again next month without anyone remembering to ask, and whether the output is a paragraph or a finished piece of work.
Claude + MCP
Sevrel is built on Claude. We are not going to argue the model is the problem — we chose it. The distinction is between a capable assistant an individual points at a folder and a system an organization deploys with policy, memory, and a record.
What it genuinely does well
- Strong document reasoning, and among the better models for long, dense contracts.
- MCP connectors reach Egnyte, Google Drive, and other repositories directly.
- Business and enterprise plans do not train on your content by default, with admin controls and SSO available.
- Excellent for open-ended analysis, drafting, and one-off questions.
Where a CRE organization runs out of road
- A connector is configured per user. There is no company-wide policy saying which properties an analyst may query and which an asset manager may not.
- No append-only record tying a question, the documents retrieved, and the answer to a user and a timestamp — the artifact an auditor or an LP asks for.
- Nothing runs unattended. A lease expiring in 90 days is only surfaced if a person thinks to ask on the right day.
- No CRE data model. It reads a rent roll as a table; it does not reconcile it to a budget or track a critical date to a property record.
ChatGPT
The most common real-world failure we see is not capability, it is shadow adoption: the tool is excellent, so people use it before procurement has approved anything, on the account they already had. The governance question arrives after the confidential document has already been pasted.
What it genuinely does well
- The most widely adopted assistant, which means near-zero training cost for your team.
- Connectors and MCP support reach external repositories, not just uploads.
- Business and enterprise tiers exclude your content from model training by default and add SSO, admin console, and compliance tooling.
- Broad general capability well beyond real estate — research, drafting, analysis, code.
Where a CRE organization runs out of road
- Consumer tiers have materially different data-handling terms than business tiers. In practice teams sign up individually on personal accounts, and confidential rent and deal terms end up outside any agreement your company signed.
- Access follows the individual who configured the connector, not a role your company assigns.
- Answers are not structured for verification against a specific page of a specific document by default.
- No scheduled work, and no CRE-specific extraction — a general answer about a lease, not an abstracted lease.
Microsoft 365 Copilot
If everything you touch is already in SharePoint and what you want is better search and summarization inside Office, Copilot is a defensible choice and we will tell you so on a call. Teams come to us when the documents are not all in Microsoft 365, or when they need CRE-specific extraction and unattended monitoring rather than ad-hoc questions.
What it genuinely does well
- Honors existing SharePoint and OneDrive permissions — genuinely strong governance, and the fairest comparison on this page.
- Enterprise audit and retention through Microsoft Purview.
- Lives inside Outlook, Teams, Word, and Excel, where the work already happens.
- If your organization is entirely on Microsoft 365, much of the plumbing is already in place.
Where a CRE organization runs out of road
- It is strongest on content inside Microsoft 365. Many CRE organizations keep property files in Egnyte, Dropbox, or Google Drive, where Copilot is not the native answer.
- It is a horizontal productivity tool. It has no notion of a rent roll, a CAM pool, a base year, or a critical date.
- Question-answering rather than work product — it will summarize a lease, not produce an abstract in your format across forty of them.
- No proactive agents scoped to a portfolio.
CoStar
This one is not really a competitor and we would rather say so than pretend. CoStar answers “what is the market doing?” Sevrel answers “what did we actually sign?” Most of our users keep both, and the two are complementary during underwriting.
What it genuinely does well
- The reference source for market comparables, listings, and submarket analytics.
- Data about properties you do not own, which no amount of reading your own files can produce.
- Established in acquisition, leasing, and valuation workflows across the industry.
Where a CRE organization runs out of road
- It knows the market. It does not know what is in your executed leases, your amendments, or your CAM reconciliations.
- It cannot answer a question about the estoppel you signed in 2019, because it has never seen it.
- It is a data subscription, not an assistant that produces work from your own documents.
Summary
Capabilities that matter once AI stops being an experiment run by one enthusiastic analyst and becomes something your organization depends on.
| Capability | Sevrel | ChatGPT / Claude | M365 Copilot | CoStar |
|---|---|---|---|---|
| Reads your document repository | Egnyte, Google Drive, and direct upload | Yes, via connectors and MCP | Strongest inside Microsoft 365 | No — market data only |

The question that decides it
Not “can it read a lease?” — everything on this page can now read a lease. The question is what your organization is left holding afterward.
When counsel, an auditor, or an investor asks what the AI was told and what it saw, an append-only audit log answers. A conversation in someone's personal account does not.
Access follows roles your company assigns. When someone leaves, access ends centrally — not whenever somebody remembers which connectors they had configured.
Scheduled agents surface an expiring lease, a rent anomaly, or a morning briefing on their own. A chat window is only as reliable as the person remembering to open it.
Questions we get asked
Can ChatGPT or Claude already read our documents?
Yes. Both support connectors — including MCP — and Egnyte publishes an MCP server, so a general assistant can reach your document repository. That is a real capability and we do not claim otherwise. The difference is what happens around the answer: who is allowed to ask, what was retrieved, whether it was recorded, and whether the workflow continues after the reply.
So what does Sevrel actually add?
Organization-level control and commercial-real-estate work. Roles and permissions your company sets centrally, tenant isolation enforced at the database, an append-only audit log of what was asked and retrieved, and workflows built for CRE documents — rent rolls, CAM reconciliation, lease abstraction, critical dates — rather than a general chat window pointed at a folder.
Do you replace CoStar?
No. CoStar is a market-data product — comparables, listings, and market analytics about properties you do not own. Sevrel works on documents you already hold. Most teams that use CoStar keep using it.
We are a Microsoft shop. Why not just use Copilot?
If every document already lives in SharePoint or OneDrive and you mainly want question-answering, Copilot is a reasonable choice and we will say so. Teams move to Sevrel when documents live outside Microsoft 365 — Egnyte, Dropbox, Google Drive — or when they need CRE-specific extraction and scheduled agents rather than ad-hoc questions.
Is a general assistant cheaper?
Per seat, usually yes. The comparison that matters is per outcome: a general assistant needs a person to ask the right question at the right moment, and produces no record afterward. Sevrel is priced per portfolio, scoped to your properties and usage.
See it against your own documents
The fastest way to settle a comparison is to run all of them on a lease you already know the answers to. We will set that up with your files.
