Private voice engine

Draft replies in your personal style

PersonaLearn reads the messages you already sent and builds a private voice profile. Drafts come back matching your phrasing, your sentence length and how you write numbers.

How it works

How your private model trains

The system reviews your outbound messages and maps your writing habits. When an inbound message arrives it writes a candidate reply for you to read, change or send.

01

Scan outbound messages

The engine reads your last hundred sent messages across connected networks and catalogues your sentence structure.

02

Build the private profile

A voice model for you alone compiles your punctuation habits, greeting style and numeric phrasing.

03

Generate the draft

When an inbound message arrives, PersonaLearn writes a candidate reply into the composer box.

04

Review and send

You read the text, change words if you want, and press send. The model never posts to a client on its own.

Scope

Data points the engine evaluates

PersonaLearn works from your outbound messages alone. It studies how you phrase things and ignores messages written by other people on your team.

What it reads

  • Your historical outbound messages
  • Your punctuation and capitalisation choices
  • Your numeric habits, like 50k against 50,000
  • Your typical greetings and sign-offs

What it never reads

  • Outbound messages written by your colleagues
  • Internal team notes and private comments
  • Inbound messages from external trading partners
  • Attached PDF contracts and bank statements

Workspace boundaries

Model weights stay strictly isolated

Your voice model belongs to your user profile. An admin in your company can confirm the tool is active. They cannot download the model or look inside your voice profile.

User-level separation

Each operator holds an isolated model file that cannot reach another member of staff's profile.

Admin boundary

A workspace admin can turn the feature on or off. They cannot read your style parameters.

Tenant training isolation

Your message patterns are never pooled to build a model for another company or an outside platform.

Profile purge

Deleting the profile wipes every associated style weight from our storage cluster inside 24 hours.

Your messages never train a base model for us or for any provider we call, and they are never pooled with another customer's data. On Enterprise the model runs inside your own deployment with your own keys.

Clean restart

Turning it back on calibrates a fresh model from scratch.

Draft comparison

Same deal terms, three different voices

A buyer asks whether the shipment lands on Thursday and wants the bill. Here is the same answer, drafted for three people who write nothing alike.

Formal, precise syntax, references the ticket number
