One concept at a time
Short explanations lead directly into terminal practice. The tutor checks understanding before increasing difficulty.
Public CLI · v0.2.1
Learn Python from zero to job-ready.
WZD is a guided, agentic tutor that teaches you in the terminal, checks what you can actually build, and moves you forward only when the evidence says you are ready.

The tutor
Guidance that makes you think, not copy.
The tutor sees your current competency, work, attempts, and evidence. It teaches at your level, gives progressive hints, and adapts the next exercise without quietly doing the learning for you.
Run real Python
Write, execute, debug, and test code in a dedicated workspace. Errors become teaching moments, not dead ends.
Earn every unlock
Time spent never substitutes for mastery. Passing assessments and project evidence unlock the next gate.
The path
Ten gates between first command and first role.
The path targets junior backend work: Python fundamentals, professional tooling, APIs, databases, production systems, and a portfolio that can survive an interview.

Your runtime
One connection. Your choice of model.
Connect OpenRouter, use OpenAI directly, or bring a custom compatible endpoint. Change the model without changing the curriculum or losing your learning state.
you › why does my loop stop early?
tutor › Let’s inspect the boundary before changing it.
What values does range(1, 5) produce?
you › 1, 2, 3, 4 — it excludes 5.
tutor › Exactly. Update the boundary, then run the test again.

Model profile
OpenRouter first. Portable always.
Your API key stays in macOS Keychain or an environment variable—not in learner progress. Switch profiles from the terminal whenever you need.

Your pace
A forecast that learns how you learn.
WZD tracks active practice, mastery velocity, retries, hints, remediation, and weekly availability. It shows a range and confidence—not a fake graduation date.
Example progress
Level 12.4 · Core Python
The active-hour estimate narrows only after enough learning evidence exists. Weekly availability changes calendar time, never mastery.

Building in public
Your first Python prompt should not be “what should I learn?”
WZD will know where you are, what you have proved, and the smallest useful challenge to put in front of you next.
