AI / Digital twins
Didymo is PTR's own digital twin product.
Built for professionals whose time is scarce and whose questions carry weight: clinicians, advisers, educators, anyone fielding the same hard conversations on repeat.
What Didymo is
PTR's own digital twin product.
Didymo answers from the organisation's own approved material, on a phone or in a browser, for the professional whose questions repeat but whose time does not.
- Answers drawn from the organisation's own approved material.
- Four ways into the same conversation: chat, a voice call, a live on-screen avatar and a booked meeting.
- Conversations linked to booking and follow-up.
- Hands off to a real person when a conversation needs it.
- Built to extend a professional's reach, not replace their judgement.
FOUR WAYS IN
Meet Didymo by using it.
Chat, a voice call, a live avatar on screen and a booked meeting are four ways into the same conversation. All four run on the phone or browser a visitor already has.
Chat
Type a question on a phone or in a browser. Didymo answers in text, drawing only on material the organisation has approved.
Loop coming: a person on a phone call at a desk, no headset
Voice
Speak instead of typing. A voice call with Didymo, on the phone or in a browser, in the twin's own voice.
Avatar
A live face on a phone or laptop screen, for the conversations that need one.
Book
Book real time with the person Didymo represents: a Google Meet appointment, made straight from the conversation.
Approved knowledge
Only what the organisation has approved.
Didymo's answers are drawn from the organisation's own approved material, not general knowledge picked up from the open internet. The professional decides what goes in, and what stays out.
Human oversight
A person stays over every answer.
The owner reviews what Didymo has said, corrects an answer when it needs correcting, and keeps the approved-source list as the boundary of what the twin may say.
Human handoff
Hands off when a conversation needs it.
Didymo is built to extend a professional's reach, not replace their judgement. When a question needs a person, the conversation moves to them, with the context already in place.
The same question, asked again and again
A visitor's first message, a harder one later, and the moment an owner checks a new answer before it goes live.
Keeping it current
The knowledge behind the twin.
An owner adds and removes source material as it changes, and Didymo answers from whatever is approved today, not a fixed set from the day it launched.
What sits behind the face
Before a twin has a likeness, it has structure: approved knowledge, boundaries, and the character built around them.
Face to face with Didymo
The visitor sees a face on a screen. Behind it is the structure and the knowledge that make the conversation possible.
"AI plays a crucial role here as well, especially now, helping to script and gamify scenarios that provide a more realistic experience. It enables us to craft narratives that adapt in real-time, making the experience progressively more challenging and thus more effective."
