Choose a specific job
Decide whether the twin should reflect on personal notes, explain your expertise, answer family questions, or help draft messages. One clear use case makes accuracy and boundaries easier to evaluate.
Build a source set you understand
Start with your own writing, structured facts, selected stories, and examples of how you communicate. Label time-sensitive information and remove details you would not want surfaced later.
Teach style through examples
A few representative responses can show tone better than a long adjective list. Include how you express uncertainty, disagree respectfully, use humor, and decline questions outside your expertise.
Keep authority and an off switch
Review replies before sharing the twin with anyone else. Control who can access it, correct its sources, export the material, and deactivate or delete the representation.
