Been thinking about why some junior devs level up fast with Cursor/Copilot/Claude and others plateau hard after 6 months.

It's not talent. It's one habit: whether you can explain the code after the AI writes it.

Devs who plateau treat AI like a vending machine. Describe the feature, get the snippet, ship it, move to the next ticket. It works, until review, until the bug shows up in prod, until they're asked "why did you do it this way" and they genuinely don't know.

Devs who level up treat AI like a second opinion, not a replacement for thinking:

• They ask for the plan before the code ("walk me through 2-3 approaches and the tradeoffs" beats "write a function that does X")

• They paste their own code back and ask what a senior dev would flag in review

• They never merge a diff they can't explain line-by-line

None of this slows you down much. It's maybe 5 extra minutes per feature. But it's the difference between getting faster over time and getting stuck depending on the tool forever.

Built Syntaxa around exactly this loop — an AI coding mentor that pushes you through those three habits instead of just generating code for you. If you're a junior dev trying to actually get better (not just ship faster), happy to answer questions on how it works.
