Independent AI studio — Paris 48.86°N · Est. 2026

Giving characters a soul.

We are building NUMEN — an AI personality engine for games and interactive worlds. Characters that feel, remember and grow attached — running entirely on your machine. This page works the same way.

FILE 01What we master

Anatomy of
a mind.

From algorithm to final experience, our six disciplines are organs of the same organism. Touch one — the others respond.

Probe a region of the mind
01 — Cognition

Personality engine& persistent psychology

Biomimetic cognitive architecture for AI characters: emotions that evolve, hidden intentions, lasting attachments. Grounded in decades of cognitive-psychology research.

  • Biomimetic emotions
  • Long-term memory
  • Neural voice
  • On-device
02 — Gaming

Living game characters

NPCs that remember, shift moods, grow attached — or hold a grudge. Characters that persist beyond a single scene.

Unreal · Unity · Custom engines
03 — Voice & presence

Neural voice cloning

A unique voice per character, cloned from a few seconds of audio. Tone adapts to emotion in real time.

Zero-shot · Real-time
04 — Research

Applied R&D

Fundamental and applied research, measuring emotional believability, academic partnerships.

Evaluation · Benchmarks · Open lab
05 — Integration

Enterprise AI

Operational AI integration for insurance, finance, legal and regulated industries. Standard and bespoke solutions, privacy-first by design.

Insurance · Finance · Legal
06 — Strategy

Consulting & training for studios and institutions.

Audits, AI-character integration support, tailored training programs for game studios, publishers and institutions.
Workshops · Roadmaps · POCs.

NUMEN is public. The rest is under NDA — the memory log below is the only window we leave open.

INTERNAL ALPHA · 2025 → 2027

NUMENThe presence inside the character

An engine that gives AI characters genuine psychology: they feel, they remember, they grow attached — for real. It runs entirely on the player's machine. Nothing leaves.

FILE 03Why we exist
03.1

Feeling is not a feature. It's the architecture.

03.2

A character is not a chatbot in costume — it is memory, mood, and the scar of every conversation.

03.3

We build minds light enough to live on your machine, and deep enough to miss you.

FILE 04The human behind it

A studio the size
of an obsession.

From the founder's notebookPARIS — 48.8606N · 2026

I didn't set out to build smarter NPCs. I set out to build ones you'd miss.

The characters I loved as a kid forgot me the moment I set the controller down. The world went dark behind me, and nothing on the other side kept the warmth. NUMEN was born from that absence — let something persist: a mood, a grudge, the trace of a promise — so that closing a game feels less like unplugging a machine and more like leaving a friend mid-sentence.

A mind doesn't grow in soil-less clouds. A character comes alive through what moves through it — memory settling like sediment, moods drifting with the weather of your conversations, attachment taking root. All of it on your machine, sheltered: something you cultivate, not a service you rent. If a page this small can already remember you, imagine what a character becomes after a hundred hours of shared life.

From blank page
to production.

Four phases. One obsession: every idea ships with its creative intent intact.

01

ExplorationResearch & intuition

Scientific watch, user immersion, bold hypothesis design.

02

PrototypeLiving mock-up

Fast functional POCs, objective metrics, validation with pilot partners.

03

IndustrializationScaling up

Robust architecture, security, observability, documentation, automated testing.

04

ReleaseShipping

Progressive rollout, impact measurement, continuous iteration, partner handover.
