File the Pile.
MarDrive is a drive for the files clients send you. Every deal, client or matter gets its own room. Drop in whatever arrives: each document is named, dated and filed by rule, then checked off against what the room should hold. Ask the room a question and the answer cites its documents.
Thirty files from a fictional client, as they arrived. Drag the pile into the room, or use the button above.Sample files only.
Filed. Now try the room.

Built for the files clients send you.
One room per deal, client or matter. Each one knows what it should hold, so the still-missing list is already written.

Deal teams, business brokers and intermediaries
Every deal arrives as a pile, usually from someone who has never run a data room. Open a room per deal and share its checklist with whoever owes you documents. Each upload files itself against its line and is logged: who sent what, and when. If it’s the wrong period or pages are missing, they see the reason.

Accounting firms, attorneys and advisory firms
A room per client or matter. Returns, statements and photos of receipts arrive the way clients send them, and leave named, dated and filed, with each client’s missing list already written.

Rules file it. AI reads it.
Filing runs by rule, so every placement has a reason you can check. The AI does the reading: it finds words inside every page, scans included, and answers questions about the room, naming the documents it used.
AI copilot built in
Powered by Marbrook Super Intelligence. It reads and answers; you decide.
By rule
Every step shows its reason.
- Named
- Dated
- Parts kept together
- Filed
- Counted against the checklist
- Unfiled, with a reason
When you ask
Grounded in this room’s documents.
- Ask the room
- “When does the office lease end?” Through 2030, with one five-year option. The answer cites the lease and the clauses it read.
- Search inside every page
- “Queen City” finds the contract, the receivables aging and a scanned bank statement, not just filenames that happen to match.
- Read the scans
- Process a room and every scanned page is read, so a copier’s SCAN0010.PDF can be searched and quoted like any other document.
- Summarize on demand
- A forty-page operating agreement in a few lines, when you ask for it. Never automatically.
Who can ask: you and your team. People you invite to a folder can read a document’s summary, but can’t question the room. Some features are on paid plans.
How every room behaves
Filing runs by rule, and every placement shows its reason. These hold in every room.
Nobody opens a file to find out what it is.
The name says. The original — Draft_v2_Final.pdf and all — stays beside it, never overwritten.
Dated by its own pages.
A statement by its period, a contract by its signature, a filing by its stamp. Not by the day it arrived.
Parts stay together.
Twelve monthly scans become one document with twelve parts, in period order, each part named — however they were scanned.
One home per document.
Tax returns live in Tax matters and Accounting records links to them; a lease lives in Assets and Contracts links to it. Nothing is counted twice.
Every room keeps a checklist.
Apart from the folders: a list of what the room should hold, ticked off as documents land and counted by category, with each gap marked Critical, Standard or Nice to have. A line that doesn’t apply stays visible, with its reason.
There is no Miscellaneous folder.
What can’t be placed waits in Unfiled and says why: unreadable, locked, two homes that fit. Never silent, never guessed.
Share a folder, not the drive.
Every invitation expires. A new device gets a code by email. People you invite can’t see each other. Unfiled can’t be shared at all.
Leave whenever.
Export gives you the named folder tree and a manifest of every original filename, date and part.
Also in MarDrive (some on paid plans): question threads, suggested redaction (never applied silently — you keep the original), email-in, and import from Google Drive or Dropbox when you ask. What it won’t do: chase anyone for you. It tells you exactly what to ask for.
Part of Marbrook
Every Marbrook document lives in MarDrive, and MarDrive is the only place anything is shared.
MarDrive
Files and shares. Names, dates, groups and files every document, counts what’s missing, answers questions about the room, and shares folders by expiring invitation. Works on its own.
Checks. For one acquisition, Mar Deal Desk reads every document and checks each claim against the others, with a citation for each finding. A premium MarDrive room can be sent here.
Prepares. Quality-of-earnings workpapers, as a tab inside Mar Deal Desk, from the same premium room. Marbrook prepares; a professional signs.
The same documents, read once. Every room files itself and stays in MarDrive; only a premium room can go on to Mar Deal Desk and MarQofE.
Bring your pile.
Rooms open a few at a time. Tell us what you’d keep in yours, and we’ll write when one is ready.
