Drop the chaos.Run the matter.
Forward an email, drop a file, speak a note after a hearing. MatterOS reads it, cites it, and turns it into a structured matter in about ninety seconds, then keeps it current every time you send in more.
Any matter. Any practice area.
Every fact cited · Nothing ever trains AI
Drop anything.
Watch it become a matter.
I sent the breach notice twice, in writing. Three weeks later they called it a “dispute.” Attaching the signed agreement…
The framework you teach,
made literal.
Every matter that enters MatterOS, in any practice area, organises itself along six pillars: matters, actions, time, team, evidence, research. We call it the MATTER Method. The Method is the spine. The legal AI is the muscle that arranges everything along it.
Read the MethodOpen it once.
See what needs you.
Not a list of folders. An instrument panel, we call it the Cockpit. Deadlines ranked by what hurts if missed, quiet matters surfaced before they slip, the one question answered the moment you sign in: what deserves your attention today.
- Cross-matter deadlines, ranked
- Quiet-matter detection
- A single, ranked queue - never a list
3 deadlines today · 6 actions this week.
Illustrative example - not real client data.
While you sleep,
the groundwork gets done.
Eight focused AI agents quietly feed your matter. Every artifact arrives cited, filed, and ready for the only thing only you can give: judgement.
Researches the legal questions in your matter and returns a brief - every point cited to authority.
Turns the facts into a step-by-step strategy memo: what to do, in what order, and why.
Reads every document and builds an organized evidence board you can search and cite.
Pulls every date out of the file into one tracked deadline timeline - nothing slips.
One matter
Reads the contract, scores it against your playbook, and proposes a fix for every risky clause.
Writes the first draft - letters, motions, memos - ready for you to edit and send.
Scans the matter for risks, conflicts, and missing pieces, then flags what needs your eyes.
Answers a question across every document at once and lays the sources out in a matrix.
Every agent shows its work. Every claim cites its source. When documents disagree, both sides ship - nothing smoothed over, nothing committed to the record until you say yes.
You get back
every week.
Our design target: the drafting, filing, chasing, and re-keying a typical small-firm week contains. Your number is your number - but every hour of it is the point.
The whole story,
in under a minute.
Watch a pile of files become a cited, structured matter - legal AI reading every page, AI agents working overnight, the cockpit clearing, and the lawyer left to do the one thing only they can: decide.
We filed your reply this morning and the hearing is confirmed for the 18th. No action needed from you right now. We will write again once the court responds.
The client sees a firm
that has it together.
Give every client a private portal in your own firm's colours. They upload documents that file themselves into the matter, and read plain-language updates you approve before they ever send. No more "just following up" emails at eleven at night.
- Private and branded in your firm's colours
- Client uploads land in the right matter, automatically
- Status updates drawn from the live matter, approved by you
- Secure PIN access, nothing for the client to forget
Not a case manager.
A practice, run.
Built by a lawyer who got tired of the gaps between tools. The small things, the ones you only miss when they are gone, are already here.
Voice capture
Speak it after a hearing. It files itself.
Cited drafts on demand
Letters, clauses, memos, sourced to the file.
Forward by email
Lands in the right matter on its own.
Conflict checks
Cleared before you say yes.
Time, as you work
Captured at your rate, in the background.
Deadlines, exported
Every date, straight to your calendar.
Your firm, your brand
One colour. The app and the portal wear it.
The Fact Ledger
Every asserted fact, its source, and how sure MatterOS is - contradictions surfaced, gaps shown, never smoothed over.
Dear counsel,
I trained as a lawyer, then spent years building the software behind the profession. It was long enough to watch good people give up at the very same point every time. Not on the law, on the setup: the quiet hour of wiring a new matter together before the real work can begin.
MatterOS exists to delete that hour. Drop in the file and it’s ready, with parties, dates, and documents already in place, so your first move on a matter is the work itself.
Warmly,
Built for work that
cannot leak.
MatterOS holds privileged client work, so we treat security as the first rule, not the fine print. Here is the plain-English version of how your data is protected.
Encrypted, always
Every document, draft, and message is encrypted in transit and at rest. Keys are managed and rotated for you.
Walled off, per firm
Your matters live behind strict per-firm isolation. Only your firm can ever see them; clients see only what you share.
Never trains AI
Your files are processed only for your matters. They are never used to train shared AI models. Full stop.
Always yours
Export your complete record anytime, and delete it for good whenever you want. No lock-in, no hostage data.
Every asserted fact is cited back to its exact source paragraph. You review and approve; the judgment stays yours.
No. Your files are processed for your matters only and never used to train shared models.
Generous credits.
Honest economics.
Every plan includes a meaningful allowance of AI work and document storage. You should never feel rationed, and we should never have to surprise you.

Before you start.
Is MatterOS a legal AI tool?+
Yes. MatterOS is AI-powered legal practice management built for solo and small law firms. Throw the files of a real case in and its legal AI reads every one, pulls out the key findings, dates, and parties, and assembles a single summarized matter page - every fact cited to its source - so you review the matter instead of reading every document line by line. AI skills and agents ride on top for the groundwork: research, drafting, deadlines, contract review.
Do I need to set anything up?+
No templates, no custom fields, no configuration. Drop in your files (PDFs, Word docs, emails, scans, photos) and the matter assembles itself in about ninety seconds.
What happens when new documents arrive next week?+
Keep sending them in - drop them on the matter or forward the email. MatterOS reads each new file, merges the new dates, findings, and parties into what's already there, and refreshes the matter's briefing. The matter page stays current for the life of the case.
Can I trust what the AI produces?+
Every asserted fact is cited back to its exact source paragraph. You read, judge, decide, and approve. The machine does the assembling; the judgment stays yours.
What happens when two documents disagree?+
MatterOS does not pick a side or smooth it over. Both dates, both accounts, ship - each cited to its own document - and the disagreement is flagged on the matter's Fact Ledger, not buried in a footnote. Facts the case should have but doesn't (a missing notice date, an undated incident) are shown as gaps rather than left silent.
Is my client data used to train AI models?+
No. Your documents are processed for your matters only and are never used to train shared models. Everything is encrypted at rest and in transit, isolated to your firm, and exportable anytime.
What does the free trial include?+
The full product for 7 days. No credit card required to begin. You get the complete Practice experience: 50 matters, 1,500 AI credits for the trial, and 50 GB of storage.
Who is behind MatterOS?+
MatterOS is built by a practising lawyer whose previous legal tech company scaled to 100,000+ lawyers. MatterOS itself is independent and founder-funded, and the founder answers his own email.
