How Personaxis works.

How do I start using a persona?

The platform is in early access. Join the waitlist on the homepage and you'll be notified when access opens. Once in, you pick a specialist from the catalog and start a session with no configuration required.

What is a persona, technically?

A persona is the complete identity and behavioral specification of an AI agent. It defines not just role and tone, but domain expertise, decision logic, tool access, memory architecture, output standards, and how the agent handles uncertainty. Unlike a system prompt — which instructs a model for one session — a persona specifies everything an agent needs to perform consistently and professionally across any context, any session, and any model version. It is what makes the difference between an agent that approximates professionalism and one that delivers it reliably.

What is persona drift, and does Personaxis handle it?

Drift is when an agent loses its configured behavior as the conversation grows, reverting to generic model outputs instead of staying in role. Every persona on the platform is evaluated for drift resistance. Our research team publishes the methodology openly.

Can I use personas in my own code?

Yes. Core persona specifications will be published as open files — you can read how the behavioral design works, understand the constraints and logic, and apply the same structure in your own setup. Programmatic access to hosted personas via API is on the roadmap for developers who want to integrate them directly into their products.

How is the quality score calculated?

Each persona is tested across four dimensions: behavioral consistency (does it stay in role?), safety coverage (does it handle edge cases correctly?), role fidelity (does output match the professional standard for the domain?), and model stability (does behavior hold across different base models?). Scores are 0–100. The full evaluation rubric is published openly.

Who creates the personas?

The core catalog is founder-built and evaluated before publishing. Community contributions are accepted but go through the same evaluation process before they appear in the catalog. There is no unreviewed content.

Are configurations open source?

Yes. The behavioral specifications behind every persona will be published under an open license — you can read how each one is designed, what constraints it applies, and how it handles edge cases. The platform adds the runtime, quality evaluation, session management, deliverable outputs, and the full catalog on top. Open specs are how trust is built. The platform is what makes them useful at scale.
