A Persona (also called a Character in some parts of the product) is a custom AI assistant that lives in your workspace. It's a saved set of behaviour, voice, knowledge, and instructions that you can apply inside Threads and Documents to get consistent, on-brand AI responses without re-explaining your requirements every time.
Persona vs. Character — are they the same thing?
Yes. Persona is the name used on the sidebar and the Personas page. Character is the term used during the Welcome onboarding (when Euryka generates your personal AI alter ego). They are the same feature.
What a persona contains
When you create or edit a persona, you configure:
- Name — how the persona is identified in the workspace
- Description — a brief summary of the persona's purpose or personality
- Behaviour and instructions — detailed guidance for how the AI should act, respond, and prioritise
- Preferred model — the AI model the persona uses by default
- Voice and tone — writing style, level of formality, perspective
Your onboarding Character
When you complete the Welcome onboarding, Euryka automatically generates a Character for you — your personal AI alter ego based on your role, interests, writing style, and personality traits. It appears in your Personas list immediately after onboarding is complete.
You can edit, rename, or archive this Character at any time.
