Your AI workforce

Two assistants: one for the firm, one for each matter.

Donna

Your virtual COO

Firm-wide intelligence with read-only financial access.

  • Firm-wide WIP, AR, and trust risk
  • Read-only financial access
  • Finds aging invoices and SLA breaches

Rachel

Your billing & time associate

Matter-level assistant for billing and time tracking.

  • Drafts billing summaries
  • Flags unbilled time and trust balances
  • Helps with document generation and matter summaries
  • Proposes actions; never executes

Guardrails by design

  • All financial actions require explicit human approval
  • Every AI action is logged in an immutable activity log
  • No training on your private data – zero-retention policy

Client portal

Case tracker your clients actually use. No app download required.

White-labeled PWA. Status, Messages, Uploads, Payments. Magic-link login. Clients can sign documents electronically through the portal with real-time status updates.

No app store friction

Opens from a text or email link

Live status

Discovery → Hearing → Settlement

Secure chat

No more WhatsApp + personal numbers

Built-in payments

Apple Pay / card for invoices

IOLTA-safe by design

Double-entry ledger, mathematically enforced.

Append-only trust ledger
Database-enforced overdraft protection
Separate operating and trust accounts
Full audit trail for every transaction

We treat IOLTA like infrastructure. The system refuses any action that would break trust accounting rules.
