MatterOS
Product

A working day.
With staff on it.

MatterOS isn’t a filing cabinet you open when you remember to. It’s the paralegal, the secretary, the docketing clerk, and the second chair a solo lawyer never had - reading, drafting, chasing dates, and answering questions cited to the page, on every matter, every day you practice.

How it works

From a pile of documents to one factual view.

  1. 01
    Documents in

    A folder, a forwarded thread, a scan, a zip of the whole case file. Everything uploads first; nothing is read until you say go.

  2. 02
    Facts out

    Every event, date, party, and assertion is extracted and pinned to its source - the document, the page, the verbatim line it came from.

  3. 03
    Evidence connected

    Facts are matched across documents. When a second file says the same thing, the fact carries its corroboration. When it doesn't, that shows too.

  4. 04
    Contradictions exposed

    Where the record disagrees with itself - two dates for one event, two accounts of one fact - both sides surface with their citations. Nothing is smoothed over.

  5. 05
    One factual view

    The Fact Ledger: what the record establishes, what supports each fact, how sure you can be, and what the discipline expects that nobody has produced yet. Exportable, cited, yours.

You still decide. You just stop doing the reading twice.

Nothing enters the record without your confirmation, and nothing in the record is without a source.

The Fact Ledger

Confidence first, source always.

The destination of the pipeline above: every fact with its status, a confidence band you can interrogate, and the document, page, and line it came from. Conflicts and gaps sit at the top, never in a side panel.

Conflicting

Gaps

  • Goods were delivered on 14 March 2026

    Conflicting

    The supply agreement and the courier thread give two different dates for one delivery.

    “…delivery to be completed on or before 14 March 2026…”

    Supply Agreement (signed).pdf· p. 7

  • Goods were delivered on 21 March 2026

    Conflicting

    Both competing dates ship with their citation. MatterOS never picks a quiet winner.

    “Left at reception 21/03, signed for by V. Rao.”

    Courier thread.pdf· p. 2

  • Notice of breach was served on 2 April 2026

    Corroborated

    Asserted independently by two documents, with the same date in both.

    “This notice is served on 2 April 2026 pursuant to clause 11.2.”

The Paralegal

Drop everything. Watch the matter assemble itself.

Within about ninety seconds, a chaotic pile of files becomes a structured matter: parties identified, chronology built, key findings surfaced, contradictions between documents exposed with both sides cited, every line of it linked back to the exact paragraph in the exact document it came from. The lawyer never types a field.

  • Drag a folder, forward an email thread, paste text
  • Parse PDFs, Word, scans, emails, photos of documents
  • Stream agent progress live: you watch it read and reason, not a spinner

Keep the matter alive without ever sitting down to type.

Tap record and speak the update. MatterOS transcribes it, understands it, files it into the right matter, updates the chronology, surfaces the new deadline, and waits for your approval before committing anything to the record.

  • One-tap capture, anywhere: desktop, mobile, after a call, after a hearing
  • Proposed-change UI: see exactly what will change, approve or revise
  • Speech becomes structured data the moment it's spoken
Cockpit
The Docketing Clerk
03 / 05

Open MatterOS. Instantly know where your attention belongs.

Not a list of folders. An answer to a single question: what needs you today. Deadlines across every matter, matters that have gone quiet, new files waiting for review, suggested next actions, surfaced and prioritized.

  • Cross-matter aggregation with priority signals
  • Quiet-matter detection so nothing slips
  • One screen that answers: what needs me today
Client portal
The Office Manager
04 / 05

The most anxious part of practice, handled.

A clean, branded portal where the client uploads documents and reads plain-language status updates drafted from the live state of the matter. You approve and share, never write another 'just following up' email at eleven at night.

  • Per-matter portal link the client just opens
  • Two-way: uploads flow into the matter automatically
  • Status updates that make a solo practice look enviably professional
Where the staff stops

Everything above drafts and proposes. Nothing sends itself.

  • Never sends an email, letter, or client update
  • Never files anything with a court or counterparty
  • Never logs or bills time without your approval
  • Never overwrites a fact you've confirmed or hand-edited
