See what your personas are becoming
A persona is not a prompt. It is a state you can measure.
Every persona carries traits grounded in validated frameworks like Big Five and HEXACO. Ensoul records how those traits move with every conversation, every memory, every day a persona lives.
Personality is state you can measure
Designed traits are what you wrote. Measured traits are what the instruments find.
Teams ship characters with no instruments attached. Personality drifts with context, memory, and model updates, and nobody is measuring it.
Ensoul makes both sides explicit. The gap between them is a number you can track, alert on, and fix.
How observation works
Every change has a cause you can open.
Administer IPIP-50 or HEXACO-60 at creation. Designed traits on record, measured traits from day one.
Traits evolve through memory consolidation, not random walk. Nothing moves without a reason.
Run the same instrument on a schedule. Change shows up as numbers, with a timeline you can read.
Open the four layers of memory behind any response and see which memories moved a trait.
Every response comes from real-time inference. Nothing is cached or pre-computed. What you observe is what the model actually does.
Two jobs it does on day one
Drift, caught in the chart
Baseline a persona, re-measure weekly, and drift shows up in a chart before it shows up in a conversation. Then open the memories that moved it.
Runs from the Studio. No code required.
The personality diff
Run the same instrument battery on the same personas across two model versions and ship the upgrade knowing your characters survived it.
Aggregate queries slice results by trait, archetype, or segment.
Four surfaces, one browser tab
Everything runs in the browser, against live personas.
Trait Instruments
Administer IPIP-50, HEXACO-60, and Dark Triad SD3 to any persona. Compare measured traits against designed traits and watch the gap.
Aggregate Queries
Ask a whole population the same question. Slice responses by trait, archetype, or segment and export the results.
Observatory
A live view of a whole world. Day chronicles, activity feeds, and trait distributions in one place.
Chat
Interview a persona directly. Probe an attitude, then open the memories behind the answer.
Where this is going
Reading the model itself
Instruments measure behavior. The next layer measures the model: trait signals read from model internals, not just from its outputs. Built to run on infrastructure you control.
Drift reports
Scheduled personality snapshots with change reports. Know what moved this week across every persona you run, without asking.
