An agentic operating system for the solo and small-firm lawyer. Drop in the files. Watch the matter assemble itself.
Why MatterOS exists
For thirty years, legal software has asked the lawyer to do the work of the machine — open the matter, name the files, fill the fields, build the structure. MatterOS flips that. The lawyer reads, judges, decides, approves. The system does everything else.
Not a list of folders — an instrument panel. Deadlines, matters that have gone quiet, actions due this week, and live workload, all surfaced and prioritized the moment you open MatterOS.
3 deadlines today · 6 actions this week.
A folder, an email thread, a Drive link, a wall of pasted text, photos of documents. No fields, no templates, no setup. Just hand it everything you have.
In about ninety seconds, MatterOS reads everything, identifies the parties, builds the chronology, surfaces findings and open issues — and files it all along the MATTER Method.
Every fact is cited back to its exact source paragraph. You supervise the machine's work and approve what's right — the judgement only a lawyer can give.
Every part of MatterOS does the mechanical work a lawyer never wanted, and lays the result out cleanly for the judgement only a lawyer can give.
Drag a folder, forward an email, paste a wall of text. MatterOS reads everything, identifies the parties, builds the chronology, surfaces findings and open issues, and files it all into the MATTER Method.
After a call, after a hearing, after a thought in the car — tap record and talk. We transcribe, understand, file it to the right matter, and surface the change for a single tap of approval.
Not a list of folders. An instrument panel. Deadlines, quiet matters, files pending review, suggested next actions — surfaced and prioritized the moment you sign in.
A clean, branded portal where clients upload documents and read plain-language status updates — drafted by the matter, approved by you, sent without writing yet another late-night email.
For David Wynn vs Marlow Group Inc. · Cal. Sup. Ct. · Employment law
Senior engineer terminated three weeks after reporting safety violations to OSHA. Whistleblower retaliation claim under Labor Code §1102.5 plus wrongful termination. Mediation set in 8 weeks.
Open any matter and understand the whole case in five minutes — briefing, parties, chronology, evidence, deadlines, and a live health score that warns you the moment a matter falls behind.
The MATTER Method isn't a poster on the wall — it's the architecture of the product. Each letter is a working surface MatterOS keeps current for you.
The case file as a living, connected object — status, history, deadlines, documents, and next steps understood in one place.
Commitments tied to legal outcomes. Every action carries a deadline, an owner, and the consequence of missing it.
Time as practice intelligence — which work is profitable, which matters drain attention, where capacity leaks.
Accountability built to outlast one person. Ownership, roles, and handover embedded in the record, not in memory.
The bridge between judgment and AI. Every fact anchored to the precise document and location it came from.
The compounding layer. One matter's learning becomes the next matter's advantage — institutional knowledge that stays.
Every matter that enters MatterOS is organized along the spine of the MATTER Method. The framework you spent years developing stops being a teaching tool and becomes the living architecture of the product. The Method is the spine. The AI is the muscle that arranges everything along it.
Read the MethodMatterOS absorbs the administrative weight a solo practice was never meant to carry — so the time you bill, and the time you keep, both go to the work that actually needs a lawyer.
I stopped being the engine room. I read, I judge, I decide — and the matter is already assembled by the time I sit down.
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.
For the single practitioner finding their feet.
For the busy solo lawyer running a real book.
For small firms with multiple seats and a portal.
Stop crawling through the engine room with a wrench. Fly the plane.
