What is AlterEgo?

An Engine that turns
Data into People

AlterEgo extracts structured behavioral profiles from text or data, and transforms them into realistic, interactive synthetic personas.

🔬 Data in → Personas out → Simulation at scale
Parses structured and unstructured data
Extracts traits, motivations, facts and social roles
Generates AI personas with memory, reasoning, and conversational flow
Modular, domain-agnostic, LLM-flexible
Architecture Overview

From Input to Insight, in Three Steps

AlterEgo orchestrates data extraction and AI personification into a single, controlled pipeline that outputs usable insights or interactions.Its layered design allows developers and teams to plug in their own data, adjust fidelity, and scale across domains.
Step 1Extract: Understand and structure any persona input
Step 2Model: Build consistent identity with attitudes, patterns and goals
Step 3Simulate: Ask questions, test scenarios, and observe synthetic behavior

Data Extraction Engine

Parse descriptions, CRM entries, or behavioral notes into structured facts and traits using semantic enrichment and domain models.

Personification Engine

Transform extracted data into consistent, realistic digital humans with reasoning, personality, memory and tone calibration.

Behavioral Simulation at Scale

Run interviews, test decisions, simulate conversations or reactions, one-to-one or one-to-many, instantly.

Composable & Integrable

Use via API or SDK. Connect with your systems, models, dashboards or products.

"AlterEgo's Synthetic Respondents provide the depth of live interviews but deliver insightsin minutes instead of weeks. Truly game-changing for product decisions."

Frequently Asked Questions

How are these personas different from a prompt in GPT?
AlterEgo builds structured identity and memory using multi-step extraction and orchestration. It’s not a simple role-play prompt, it maintains consistency, uses a custom trait structure, and simulates behavioral patterns, not just surface tone.
Can I use AlterEgo even if I have no data?
Absolutely, you don’t need any existing data to generate realistic synthetic users.AlterEgo is built to work from zero-knowledge.

All you need is a natural language description of who you want to simulate, for example:
“Young parents in urban areas, early 30s, tech-savvy but budget-conscious. Often compare products online, worried about safety and reliability.”

From that alone, our Data Extraction Engine builds a structured profile:
- Demographics
- Psychographics
- Behaviors, values, goals
- Common pain points and decision criteria

Then our Personification Engine creates interactive personas with memory, tone, and realistic reasoning.
You can start testing, asking questions, or simulating behavior immediately.
Can I use my own customer or patient data?
Yes. AlterEgo can ingest CRM, survey, or even interview transcripts to create data-backed personas. You can choose whether to generate synthetic traits or augment existing profiles.
What about accuracy or reliability?
We benchmark every persona type against real human responses using semantic similarity, sentiment range, and reasoning structure. Typical fidelity ranges from 75–90% vs. real panel answers.
Is it GDPR/compliance safe?
No real user data is exposed. You control what is input. When built with synthetic inputs, AlterEgo is fully privacy-preserving and can simulate even sensitive roles without legal overhead.
