Intro then AX coding is the natural order. Add a language course when you get stuck on syntax.

Here is what you do at each level
The intro makes run-and-check feel ordinary. AX coding makes the same work pass tests more than once.
- LEVEL 1Solo practice
Intro
Free
Ask AI to do a job, run what comes back, and fix it when the result is off. You can follow this even if you have not written code before.
What you do
- Hand over a short request
- Run the code you get
- Ask again when the result is off
- Pass tests in the browser lab
Once that feels ordinary, the next level adds a spec and tests.
- LEVEL 2Solo practice
AX coding
KRW 99,000
You learn the difference between 'it worked once' and 'it still works when you run the tests'. Write what done looks like first, then fix from the failures.
What you do
- Pack context as a token budget
- Lock a spec before implementation
- Run evals that include known-bad cases
- Let a failing eval be the next input
- Fill a one-page team guardrail
You run it in the browser. When you get stuck, start from the test that is still failing.
- LEVEL 3Solo practice
Language basics
KRW 30,000
Write and run small programs in Python or Node.js. Useful when syntax is the thing slowing you down.
What you do
- Run the language locally in the lab
- Write a small program
- Read an error message
Pick this when grammar or running the language is the blocker.
- LEVEL 4Solo practice
Language applied
KRW 50,000
Connect a screen, a server, an API, and a database, and build one slice of a web app.
What you do
- Split frontend and backend
- Move data over an API
- Store and read from a database
Take this when you want to see what happens behind the screen.
How it works
Build, run, fix, run again
See what you are making, run it, then change only what failed. Repeat until it passes.
- 01
Spec
Lock completion criteria in a document.
- 02
Run
Execute the agent or the code once.
- 03
Eval
See which cases passed.
- 04
Patch
Change only the failing case.
- 05
Stop
Halt on a full pass or a retry limit.
AI systems
Search and graph in one pipeline
KRW 149,000
AI systems
A solo hybrid RAG track: PostgreSQL full-text search, pgvector, and Apache AGE. This price does not include a 5-10 person team runtime or shop-building lab.
What this track builds
Hybrid RAG
Blend keyword and vector search, then add graph expansion, rerank, and a grounded answer.
- PostgreSQL
- pgvector
- Apache AGE
- RRF
- Eval
What you leave with
- Retrieval pipeline
- Eval set
- Grounded answer
This is a solo systems track. It is not sold as a role-split team project.
Techniques
- Full-text search
- Vector search
- RRF
- Rerank
- Graph expansion
- Grounded answer
- Regression eval
eval-03
A known-bad query produced an ungrounded answer
loop/rerank-guard → main
1 of 8 evals failing
If citations are empty, stop the loop and rebuild the rerank input.
Org AX
Your team works to one standard
Inquiry
Org AX
A two-day workshop sets the team's standard, followed by 90 days on the platform together. Pricing depends on team size and scope, so we quote on inquiry.
When leaders and engineers apply different standards to AI output, the bar for reviewing that output shifts from person to person. The workshop ends with one page of rules the team can actually keep.
What you take home
- One page of AI usage rules your team keeps
- Where API keys and secrets live, and how to handle them
- The scope of changes AI may make on its own
- The points a person always reviews
- 90 days on the platform
How it runs
- 01Agree on what the team's words mean
- 02Draft the team rules together
- 03Apply them to real code and run the tests
- 04Decide where a person reviews
- 05Work to those rules for 90 days

The intro course can be taken without payment. Org AX starts as an inquiry.
For teams
Running this with a team
Org AX is a two-day workshop plus 90 days of seats. Headcount and repo scope are set after you enquire.
Frequently asked questions
Is this workable if I have never written code?
The intro course assumes you have not. Follow the screens from installation through to running it and you will be fine.
Can I just take the free intro?
Yes. You can take the intro course without paying and decide afterwards whether to continue.
How much time does this take per day?
There are no fixed class hours. You work assignment by assignment, so you go at whatever pace your week allows. Intro through Advanced back to back runs about three months.
What happens when I get stuck on my own?
Submit the assignment and you get feedback on what to change and why. You are not left to carry a blocker into the next assignment.
Does AX coding install Claude Code on my machine?
No. You run a spec-and-eval loop in the browser workspace. A loop coach points at failing evals, and may call a model API for the next patch. Local CLI setup is not in the course.
Is AI systems a team project?
No. It is a solo hybrid RAG track.
Who is Org AX for?
Teams where leads and builders need a shared language of spec, eval, and approval. It is a two-day workshop plus 90 days of seats, started by enquiry.
Can a whole team at my company take this together?
Yes. Use the team training enquiry and we match headcount and repo scope.
