I, AI, U.We help your business
make the AI conversion.

IAI builds and runs its own services and has put AI to work in each of them. We bring that experience to your business — finding where AI fits, then planning, building and running it with you.

What you can bring to us

AI conversion is not buying one more tool — it is changing how the work gets done. We only propose what we have already done in our own services, and we carry it ourselves from planning to launch and operations.

AI conversion & automation

We find the parts of your work that AI can take on, then build tools and pipelines with generative AI and speech synthesis that actually run.

Tellby — audio guides produced at scale / HUMAN WORK — side-job books, growing daily

Mobile apps

From idea to app: UX, iOS and Android development, store review and launch, and operations after launch.

Tellby — shipped on iOS and Android / BioHACK — iOS app

Web services & platforms

Services with accounts, payments and admin tools — from a landing page to a full platform.

Grey Social Club — class platform / T&P · HUMAN WORK — web services

Data & location

We collect and clean scattered data, make it usable, and add map and location features.

Tellby — location-aware playback as you walk

Aerial filming & video

Drone aerial filming and short-form video that show places and stories.

Short-form channels produced and run first-hand

Data & AI education

Hands-on training for companies and institutions, drawn from building real services.

Custom curriculum · practice-first

Projects

Services we built first and run every day — travel, music, daily habits, investing methods and the world of work. Everything we propose, we have tried here first.

Travel · AudioLive

Tellby

An audio guide you listen to as you walk

Technology
Public sources such as Wikidata and Wikipedia are gathered per place, a generative language model writes the story script, and speech synthesis (cloud and on-device Korean TTS) reads it aloud. The app is React Native (Expo); the backend runs FastAPI and PostgreSQL, with audio stored on Cloudflare R2.
AI & automation
Pick a place and the pipeline runs on its own: gather sources, split into sections, write, translate, and render the audio. When a listener plays the first section the next ones are prepared ahead, and playback continues as they walk close to the next spot.
Impact
Audio guides that used to be written and recorded one place at a time can now be extended to places around the world at consistent quality. Production cost falls, and listeners hear the story of where they stand in their own language, wherever they are.

Music · ClassesLive

Grey Social Club

Sampler classes, plugged-in analog sound

Technology
Speech recognition that transcribes each class video (faster-whisper on our own server), a rule engine that finds steps and materials in the transcript, and an optional LLM layer that only polishes wording.
AI & automation
When an instructor uploads a video, the transcript and step markers are generated automatically and power section navigation in the player. After each sale, payout amounts and withholding-tax receipts are prepared automatically; an admin only reviews them.
Impact
Instructors can focus on filming instead of editing and tidying captions. Learners jump straight to the step they need and replay just that part.

Habits · Daily lifeIn development

BioHACK

Train body, mind and social skill together — one small practice card a day.

Technology
Native apps built with SwiftUI (iOS) and Kotlin/Jetpack Compose (Android), backed by Supabase and Cloudflare R2/Workers. Card recommendations run entirely on the phone with a rule-based engine plus diversity re-ranking (MMR).
AI & automation
Generative AI pre-writes a “why this card, now” line for every practice card in several languages at build time, so it ships inside the app. Voice-guided sessions are synthesized and deployed automatically with local text-to-speech, and card references are looked up through the PubMed API and machine-checked instead of being generated by AI.
Impact
No AI is called at runtime, so personal records never leave the phone and AI costs don't grow with the user base. Multilingual copy and audio that would take a long time by hand can be produced and revised directly and quickly.

Investing methods · LeaguePublic beta

T&P

A league where famous investing methods become characters and compete in daily simulated matches.

Technology
Investing rules are written in a purpose-built strategy language (DSL) and run identically through a one-year historical replay and a live simulation engine. A settlement pipeline handles the Korean and US markets separately, each with its own trading calendar and market close.
Automation
Many investing methods trade in simulation every day without human intervention, and settlement, standings, daily reports and records are produced automatically after each market close. A trading approach a user describes in plain words is turned into rules and replayed over the past year right away.
Impact
Methods are compared fairly under the same rules and conditions, so anyone can see where each approach shines or struggles without risking real money. Running daily leagues across two markets takes little enough effort for a single operator.

Work · BooksPublic beta

HUMAN WORK

Every kind of work in the world, one book at a time.

Technology
We turn YouTube videos in many languages into text with Google NotebookLM, then use Claude (Haiku and others) to extract each business model into a structured card. Book content is kept in a cell-level table, and rule checks plus LLM review keep the writing consistent.
AI & automation
Every day the whole pipeline runs without hands-on work: finding side-job videos across many countries, collecting transcripts, writing cards and drafts, researching figures and sources on the web, and publishing to the site. People set the rules and only review the cells that get flagged.
Impact
A world survey of side jobs that would take years to write by hand keeps growing every day, at a very small AI cost per book. Readers find real cases from other countries, hard to come by in Korean, with new ones every day.

How a project runs

  1. 01

    Consult

    We listen to what you want to achieve. The first consultation is free.

  2. 02

    Scope & quote

    We scope what matters most and propose a schedule and cost.

  3. 03

    Design

    We show screens and structure first and refine them together.

  4. 04

    Build & review

    Short cycles, frequent demos, your sign-off at each step.

  5. 05

    Launch & run

    After launch we keep fixing and growing it with you.

How we work

We build it ourselves

Planning, design, engineering and operations are done directly, with no hand-offs, so what needs fixing gets fixed right away.

We start small

Each service begins with one clear use and grows by listening to the people who use it.

We keep it running

Shipping is not the end. We look after every service every day.
