About MatterOS

MatterOS: the Notion operating system for lawyers

MatterOS is a Notion template for lawyers built on the Matter Method. It gives you six connected databases (Matters, Actions, Time, Team, Evidence and Research), client and invoice records, a practice dashboard, a playbook, a setup walkthrough and an AI prompt pack, all inside your own Notion workspace. It is a template, not hosted software.

  • The Matter Method playbook
  • Setup video walkthrough
  • AI prompt pack
  • Lifetime updates
PartWhat it does
MatterMatters hub: one page per case with status, parties, key dates and every linked record.
ActionsActions database: deadlines, owners, urgency type and “consequence if missed”.
TimeTime log: entries linked to matters, with practice-level views.
TeamTeam layer: roles, responsibilities and handover notes on every matter.
EvidenceEvidence register: classification, tags and review status per document.
ResearchResearch library: notes linked to matters, cross-referenced by practice area.

Alongside the six, MatterOS includes Clients and Invoices records linked to every matter, ready-to-use AI prompts to summarise a matter, draft a client update or build a next-steps checklist, and a quick start guide that takes you from duplicating the template to opening your first matter.

How does it work in practice?

  1. 1

    Duplicate it

    After purchase you receive a link to duplicate MatterOS into your own Notion workspace.

  2. 2

    Add your first client and matter

    Replace the sample entries with real ones; start with Matters and Actions.

  3. 3

    Log the first action and its deadline

    Every action has an owner, a deadline and a matter.

  4. 4

    Run your week from the dashboard

    Deadlines, overdue actions, unbilled time and matters without a next step.

Who is it for?

  • Solo practitioners and small firms of two to ten lawyers.
  • Young lawyers building a practice.
  • In-house counsel who need matter tracking without client billing.
  • Any practice area: the six parts of legal work are jurisdiction-neutral and every field is editable.

What MatterOS is not

MatterOS is not software-as-a-service, not a replacement for trust accounting or court-rules calendaring, and not legal advice. It does not host your data, send emails on your behalf or integrate with billing systems on its own. Where you need those, use dedicated tools alongside it.
