Client instructions & approval workflows

Take an instruction, route it, approve it and record it in one sealed thread. Private AI reads the request and drafts the workflow — in an isolated environment operated by Letro, never a third-party model.

How it works

One instruction, five recorded moves

Scroll to run
Step 01 · Instruction in

The client writes once, in the channel

A structured instruction, end-to-end encrypted, with the files attached to the matter — not to an inbox.

Matter M-2214New
“Proceed with phase 2 of the acquisition. Confirm the revised indemnity cap before Friday.”

Step 02 · Review

Private AI turns it into a workflow

It summarises the ask, names the approvers your policy requires and flags what is missing. The model runs in an isolated environment operated by Letro — not a third-party service.

  • Missing: signed board resolution
Step 03 · Approval

The right people, in the right order

Roles decide who can view, approve or escalate. If an approver goes quiet, the escalation path moves it on.

Step 04 · Confirmation

Confirmed where the decision was made

The client’s counter-approval lands in the same thread, timestamped on delivery and receipt. No printing, no scanning, no third mailbox.

Step 05 · Sealed record

Every move, provable ten years later

Who asked, who approved, what they saw, when they confirmed — one tamper-evident record per matter.

Private AI

The model never leaves the encryption boundary

Letro’s AI runs in an isolated European environment operated by Letro and assigned to your organisation. It reads instructions and drafts the approval path — no data to a third-party model, nothing used for training.

Explore Private AI

Reads the instruction

Six pages of client email become three dated asks with the obligations named.

Drafts the workflow

Suggests reviewers, approval order and deadlines from your own policy — you confirm or change them.

Watches the gaps

Flags a missing document, a stale approval or an instruction that contradicts the last one.

Workflow builder

Design your workflow

Pick the moves your matters actually need. The path assembles as you choose — bring it to us and we configure it in your Letro deployment.

Available steps

Intake and the sealed record are always on — a workflow without either is not auditable.

Security & deployment

Built for sovereignty, not retrofitted

Built on Matrix, an open standard for decentralised communication. Message content stays end-to-end encrypted while the organisation keeps its controls around the workflow.

01

End-to-end encrypted content

Instructions, files and confirmations are readable only by the parties on the matter.

02

Role and policy controls

Who can view, send, approve, escalate or administer — modelled per entity, team and counterpart.

03

Your deployment model

Cloud, Dedicated or Sovereign — including air-gapped. With a Sovereign deployment, no one else holds your data.

04

Tamper-evident audit trail

Every interaction is timestamped, traceable and exportable for a regulator or a dispute.

Bring us one workflow that keeps slipping

45 minutes. We map it, build it in your Letro deployment and hand you the audit trail.
