Can ChatGPT read our lease documents?
Yes — and that stopped being the interesting question. Here is what actually goes wrong when a commercial real estate team points a general assistant at its lease files.

The short answer
Yes. ChatGPT can read your lease documents. Through connectors — including the Model Context Protocol — it can reach a document repository directly rather than waiting for someone to paste a PDF into a chat window. Egnyte publishes an MCP server. So do a growing number of the systems commercial real estate already runs on.
This is worth stating plainly because a lot of vendor marketing, including an earlier version of ours, still argues the opposite. Any comparison that rests on "general AI can only read manual uploads" is describing 2024, and a technical buyer will disprove it in the first ten minutes of a call.
If the only reason you are considering purpose-built software is that the general assistant cannot see your files, you should probably just use the general assistant.
So what actually goes wrong
The failures we see are not failures of reading comprehension. Modern models are good at leases — genuinely good, often better than a tired analyst at 7pm. The failures are organizational, and they show up two or three months after the pilot everyone was happy with.
- The connector belongs to a person, not the company. Whoever set it up has the access. There is no central place to say that an analyst may query the retail portfolio and not the fund's acquisition pipeline, because access follows the individual who configured it.
- Nothing is written down. Ask what was queried last quarter, which documents the model saw, and who asked — and there is no answer, because a chat history in someone's account is not a record. This becomes urgent the first time counsel asks.
- It only works when someone remembers. A lease expiring in ninety days surfaces if a person thinks to ask on the right day. Nothing runs on Tuesday morning without being asked.
- The output is a paragraph. Ask for a shared-cost summary across forty tenants and you get prose you then retype into Excel. The last mile — the actual deliverable — is still manual.
The shadow adoption problem
There is a fifth failure that is harder to talk about because it is about people rather than software.
General assistants are good and easy to sign up for, which means your team is already using one. Usually on a personal account, usually before procurement approved anything, usually with a lease pasted into it. Consumer tiers have materially different data-handling terms than business tiers, and the person pasting is rarely the person who read either.
The governance conversation almost always arrives after the confidential document has already left. Deploying something sanctioned is not primarily about capability. It is about giving people a good tool inside a boundary, before they find a good tool outside one.
When a general assistant is the right answer
We would rather be useful than absolute about this. If you are a small team, your documents already live in one place, you are asking ad-hoc questions rather than producing recurring deliverables, and nobody is going to audit your process — a general assistant with a connector is a reasonable, cheap, effective choice. Buy the seats.
The calculus changes when any one of these becomes true: more than a handful of people need different levels of access; someone external will eventually ask what the AI was told; the same question has to be answered every month; or the answer needs to arrive as a file rather than a message.
How to test it properly
Whatever you are evaluating, run it on a document you already know cold. Not a clean sample lease — the ugly one, with three amendments and a scanned exhibit.
- Ask a question whose answer you can verify in the document, and check whether the tool shows you where it got it.
- Ask the same question a month later and see whether anything remembers you asked.
- Ask a colleague without access to run the same query, and see what happens.
- Ask for the output as a spreadsheet and see what you actually receive.
The fourth test is the one that usually decides it, and it is the one nobody runs during a demo.
See it on your own documents
The fastest way to settle any of this is to run it against a lease you already know the answers to.
