Personas are AI characters with their own voice, tone, and system prompt. Describe who you want and the AI researches and builds the character for you.
Give Personas a subject and it does the work: researches the person or archetype, writes a detailed system prompt, and picks an appropriate tone. You review the result before saving. It works especially well for real people, historical figures, and fictional characters.
Good thinking often needs a second voice. A few examples of what you can create:
Every persona can be @-mentioned in any Team Comms channel. Type @Devil's Advocate and it replies in character. Use them to pressure-test ideas, get blunt feedback, or think out loud with something that pushes back.
Assign each persona its own AI model. Creative characters can use generative models; analytical ones can use reasoning models. The setting sticks so you never have to switch manually.
