Booking finishes with a Google Meet in the diary of the person Didymo represents. Choosing a time from what is free. ### Pick a time inside the conversation No form to fill in and no email thread. The visitor chooses from what is actually free, and the appointment is made where they are already talking. A meeting with one seat still empty. ### The seat is the professional's, not the twin's The meeting is with the person, and Didymo has already carried the context to it, so the conversation starts where the visitor left it rather than at the beginning. Reviewing what Didymo is allowed to draw on. 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. Reviewing and correcting an answer. 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. Handing the conversation to a person. 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. ## Whichever way in, the same twin A visitor picks the way that suits the moment. What sits behind the answer, the approved material and the boundaries around it, does not change with the choice. Starting the conversation in writing. The same twin, typed or spoken. Meeting the twin face to face. ## 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. A visitor's first message to the twin. A harder question, escalated for review. Testing a new answer before it goes live. Arranging the material the twin may use. 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. Before the skin, the mesh ## 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. A twin takes shape above its knowledge. A manager, on screen, mid-conversation. > "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."
