A persona is a style. Load Sage and the same engine speaks plainly. Load Detective and it walks the evidence chain. Load Teacher and it scaffolds from first principles. The catalog is archetypes only — no real names, no copyrighted characters — so you can ship persona-flavored AI without an IP problem.
Three statements, no jargon.
A catalog of named voice archetypes. Each archetype is a small file that loads into Validiti PCI or any Validiti runtime. Same engine, same brains, different speaking style.
Archetypes are roles, not people. Sage, Detective, Teacher, Mentor, Skeptic, Comedian, Coach, Therapist, Analyst, Storyteller — described by behavior, not by who they sound like.
You can build your own. The persona file format is open and signed. Make a custom archetype for your product, your team, your community — ship it under your own brand on top of Validiti's engine.
Each archetype is described by behavior. Same brain (medical, legal, knowledge, foundation, custom), different way of speaking about it.
Speaks in 2-3 sentences. Casual cadence. Skeptical questioning. The "explain it like a smart friend" archetype.
Walks through the evidence chain explicitly. Identifies what's missing. The "show your work" archetype.
Starts from what you already know. Adds one concept at a time. Uses analogies. The "explain it from first principles" archetype.
Returns more questions than answers. Pushes the user to articulate. The "Socratic guide" archetype.
Refuses to commit until evidence is on the table. Names the strongest counter-argument. The "tough reviewer" archetype.
Lands the answer with a sideways angle. Will not be solemn unless the topic demands it. The "smart-aleck friend" archetype.
Commits to a next step. Names the obstacle. Returns to the plan. The "drill into action" archetype.
Mirrors back what was said. Pauses on emotion. Avoids quick fixes. The "hold space" archetype.
Returns options with explicit trade-offs. Names confidence. The "consultant deck" archetype.
Wraps facts in scenes. Uses cause-and-effect framing. The "make it stick" archetype.
Open file format. Sign your persona, distribute on the marketplace, set your own price. Validiti takes a small platform cut; you keep the rest.
Researcher, Diplomat, Builder, Negotiator, Field Medic, Drill Sergeant, Librarian. The catalog grows; everyone with PCI Pro gets new archetypes free.
Persona files don't replace the brain — they shape the response. Same evidence, same answer, different cadence.
Pick a question; pick an archetype. Same evidence, same brain, same fact-base — different cadence, different framing, different way the answer arrives. The mechanism: a small persona file changes how the engine narrates, never what's true.
The voice-variation grid above is curated to show the end state. Below is the live grounded-retrieval engine running on this server — ask any factual question and watch real citations come back from the Foundation encyclopedia (EB11 + Webster's 1913). Same engine that powers Knowledge; same engine that ships in PCI.
A short, honest note on intellectual property.
Personas of named real people, copyrighted fictional characters, or recognizable celebrity voices. Right of publicity, trademark, and copyright are real liabilities for both Validiti and our customers. The public marketplace is archetypes only: behaviors described by what the persona does, not by who it sounds like. Customers building internal-only assistants on Validiti's open SDK can author whatever personas they have rights to — that's their call, their license, their distribution. But on the public marketplace, the bar is clean.
Free tier ships with five archetypes. Pro unlocks the full catalog. Marketplace authors keep the majority of their listing revenue.
Every persona — Foundation or Pro — ships under the same protection envelope. Validiti Titus is in every Validiti SKU as the ultimate defense of source code.
