Due-diligence document review runs an AI first pass over an entire data room: it reads every file, checks each one against your diligence checklist, and flags the risks that matter, like change-of-control, assignment, and indemnity clauses, with a link to the exact page. It does not make the final call. A reviewer confirms every flag. Most teams are live in two to three weeks.
The problem
A data room is technically organized, which is exactly what makes it slow. Thousands of files arrive in a structure the other side invented: folders named after whoever uploaded them, contracts split across sub-folders, board minutes next to lease amendments, and a stack of scanned PDFs where the text is really just a picture. You have a checklist of what matters and a signing date on the calendar. Between the two sits a pile nobody can read fast enough.
Put a number on it. Bloomberg Law's standard M&A due diligence request list runs to 174 document types across more than ten categories, and in a live deal each type expands into many individual files, so a mid-market data room routinely holds several thousand documents. Model a first pass at 3,000 documents read carefully against a checklist at about five minutes each: that is 250 hours of reading, and a two-person review team carries roughly 125 hours each. Squeezed into a four-week diligence window, that is about 31 hours a week per reviewer, on top of everything else on their desk. (The 174 document types is Bloomberg Law's figure; the hours are a modeled estimate built from it, not a client number.)
The hours are the visible part. The costlier part is the risk nobody flagged in time: the change-of-control clause that lets a key customer walk the day the deal closes, the assignment restriction that blocks a transfer everyone assumed was clean, the indemnity cap that turns out far lower than the deal was priced against. These surface after signing, when they are expensive to fix or too late to fix at all. Deals slip while the team re-reads what it already read, and decisions get made off a partial view of a data room nobody had time to finish.
How the automation works
Point it at the data room.
You connect the source: a virtual data room such as Datasite, Ansarada, iDeals, or Intralinks, or a shared-drive export from SharePoint or Google Drive, along with the diligence checklist you are reviewing against.
It reads and classifies every file.
The system pulls the text from each document, runs scanned pages through text recognition so old paper contracts become readable, sorts every file into the right checklist category, and reads each one for the specific clauses and risks you care about.
It returns a flagged review, with the receipt.
You get a list of every flag by category (change-of-control, assignment, indemnity, non-compete, missing signature, and so on), each with the exact document, the page, and the quoted language, ready for a reviewer to confirm or clear.
The pieces are proven: text extraction, recognition for scanned pages, a model that reads a clause in context, and a layer that sorts documents against a checklist. The real work is the wiring. It flags items for a human to review rather than making the final legal or deal call, and it cites the exact document and page for every flag so a reviewer can verify it in one click. The hard, judgment-heavy part is the input: data rooms come structured differently every time, plenty of documents are scanned at poor quality, and knowing which risks actually matter for this deal is a call that depends on the thesis, the sector, and the price. That is what gets set up, tested, and handed over during implementation.
What this looks like in practice
Reviewing a target's data room of about 3,200 files against a change-of-control and assignment checklist, with a signing date two weeks out.
- Two associates split the data room and read files folder by folder, and most of two weeks goes to the first pass alone.
- A change-of-control clause in a key customer contract sat three folders deep under a mislabeled name and nearly went unflagged before signing.
- Partners get the risk summary late, so questions to the other side go out close to the deadline, when there is little room left to negotiate.
- The AI first pass returns every change-of-control, assignment, and indemnity clause across all 3,200 files in hours, each with the document, page, and quoted text.
- The associates spend their time confirming and judging flags instead of hunting for them, and the buried customer clause shows up in the first list, not the last read.
- Partners get a flagged risk summary in days, so questions to the other side go out early with room to push back.

Who this fits
- Deals or reviews where a data room of thousands of files has to be read against a checklist before a deadline
- 10 or more employees, with a team that reviews data rooms or diligence files regularly
- Due-diligence, contract, or compliance review as the work type: M&A, investment, vendor onboarding, or audit
- Accuracy matters, so every flag has to cite the exact document and page for a human to confirm, and the tool never decides on its own
