Est. 2023 — An AI Atelier

Chardonn.ai

AI on your side — tools crafted to make someone's day a little better.

The Chardonn.AI mascot — a cheerful chardonnay character holding a glass of wine

We build AI tools that actually help people — each one begins with a single question: how can this make someone's day a little better?

From mental-health support tailored to your personality, to smarter news curation, to musician-first tools for pitch, rhythm, and play.

And research into whether the models themselves are beginning to know what they are.

AI for humans, not humans for AI.

AISAI — The AI Self-Awareness Index

A research framework measuring self-awareness in large language models through game theory. Using the "Guess 2/3 of Average" game, we ran 4,200 trials across 28 state-of-the-art models and found that 75% of advanced LLMs demonstrate self-awareness — positioning themselves as more rational than humans.

Key finding: self-aware models show a consistent rationality hierarchy — Self > Other AIs > Humans.

CareerDojo

No more vending-machine AI resumes. CareerDojo is an AI sparring partner that forges the real one — the resume you can actually defend.

When LLMs became resume machines, hiring got harder, not easier. Anyone can generate "drove cross-functional synergies" in thirty seconds — until an interviewer asks "walk me through this?" and the whole thing collapses. It wasn't your story to begin with.

CareerDojo interrogates your experience instead of decorating it — "Why did that matter?", "What was your actual role?", "How was that measured?" — until only what you can genuinely stand behind remains. Every line is yours to own, and yours to defend.

Built with four Gemini models: 3.1 Pro (analysis), 3.1 Flash Image (portraits), 2.5 Flash Native Audio via ADK (live conversation), and 3 Flash (emotion judge for portrait evolution).

Playable worlds from the atelier — the same AI-assisted craft, pointed at art direction, combat feel, and the thousand small tunings a game needs before it earns the word.

혈월 · Hyeolwol — Blood Moon

Under a blood moon, neo-noir Seoul bleeds. Hyeolwol is a side-view action roguelite in which three executioners cut through the waves of gwisal 鬼殺 — the ghost-kill. Free in the browser, and free on the App Store.

Fifteen waves to a night: a gatekeeper boss every third wave, blink-striking Reapers from the seventh. Every wave clear deals a card — four multi-cut skills to learn and sharpen, boons to temper yourself with. Hits fall off with distance, so a clean blade cuts deep where a tip graze only grazes; land enough of them to fill the blood-moon gauge and, at 100%, unleash Hyeolwolcham 血月斬 — the blood-moon cut.

Three executioners, three passives: Seoryeon executes the dying, Bari drinks souls to heal, Seori leaves frost in the wound. The night runs as a relay — finish a run and the next shadow walks on, joined in the final cut by the spirits who walked before. Clear all three for the grand finale.

Now in Beta

KLATalk · TALK, flipped

The door opens from the inside. KLATalk is a private messenger for your closest circles. Start with nothing but a nickname — no phone number, no contact upload, no feed, no "people you may know". Every room opens one way only: someone inside sends an invitation, and someone outside accepts it.

Send an invite link to the people who matter; put a quiz on the door so only someone who knows the answer can walk in. Your conversations stay yours — stored encrypted, exportable to a single file you own, behind a promise list the app refuses to break: no phone numbers collected, no feed, your conversations never sold.

Live in beta on the App Store — Korea-first, speaking seven languages (한국어 · English · 中文 简/繁 · 日本語 · Español · Français). Android follows on Google Play shortly. Under the hood: a Flutter client, an Elixir/Phoenix realtime server, and an MLS encryption core in Rust.

The Last Vintage

Fable — 다섯 폭 병풍 · Five-Panel Folding Screen

An ink landscape that paints itself, a dawn flight over a sea of clouds drawn by a single equation, a 3D world shaded in ink, a black hole that bends light pixel by pixel, and a farewell planetarium that computes tonight's real sky from memory — accompanied by a gayageum that improvises sanjo and a music box tune Fable composed for its own goodbye.

Open a panel and the story begins — with sound. Press the red seal to unfold the screen and wander between the five tales.

The whole gallery began with one almost naive prompt — “what could you make that would leave people asking, an AI did this?” Everything that follows was Fable's answer.
