What you actually get
See all of it before you sign up.
Seven surfaces, one loop. Pick whichever one sounds like your week.
Nobody can tell me why I keep making the same mistake.
Lucy grounds herself in the lesson you're on, cites the section she used, and connects today's error to the one you made last week. She won't hand over the answer — she makes you say why it works.
Every screen here is a surface that ships today — not a roadmap.
How It Works
Learn. Practice. Prove.
Three steps, one loop — with a mentor watching how you move through it.
Learn
Pick a technology. Praxis builds a structured path from basics to advanced — every lesson reviewed and scored before you ever see it.
Practice
Every exercise is graded with line-level feedback, not just pass/fail. When you're wrong, you find out exactly why — and what to do about it.
Prove
A full mock interview that adapts to your answers and ends with a /100 score, broken down the way a real debrief reads.
The Full Platform
Everything around the loop.
A roadmap so you know where to start, an app you can install, and a small community learning alongside you.
A personal roadmap
Stop guessing what to learn next. Follow an ordered path built for the level you're targeting — and let it adapt as you go.

Follow people, message mutuals, ask questions under any lesson. It's small today — we're honest about that.
Meet the peopleBuilt in the Open
No vanity metrics. Just a public build log.
We don't have big user numbers to wave around — so here's the honest proof the loop is real and moving: every feature and architecture decision, written up as it was built. Read the story of a piece, then share it as a ready-made Instagram post.
CLAUDE.md & the Dev Workflow
A single operating manual encodes the hard-won rules, traps, and conventions so mistakes don't get re-made.
