Inside Kodexing

This is the actual product.

Not mockups. These are the real screens — a working neural-network trainer, your cohort standing, and the career hub that puts you in front of live roles.

What you actually build

Nine studios. Zero tutorials.

Every studio exists to move you from “I finished a course” to “I shipped this, and here’s the code.”

Neural Network Trainer

Build a real MLP layer by layer and watch forward-prop, backprop and gradient descent sharpen the decision boundary — live.

LLM Simulator

Watch a prompt travel through a transformer: tokenize, embed, context window, attention heads, blocks, generate.

Prompt Engineering Lab

A/B two prompts against the real model. Compare quality, tokens, cost and latency side by side.

Data Modeling Studio

Upload a CSV, X-ray every column, then train real models and score them honestly against an always-guess baseline.

FlowCoder AI

Draw the logic on a canvas, generate real code, then step through execution and watch your variables change.

Architecture Studio

Design multi-cloud systems from a 632-service catalogue with live cost, carbon and a 9-axis resilience score.

Anytime Code

A never-repeating practice library across 20 topics. Every question lives in exactly one place — no duplicates.

AI Coding Lab

A real editor with an AI mentor that explains, fixes, optimises and hints — plus a static security review of your code.

Career Hub

Live fresher and internship roles, an AI resume builder, and company research — the last mile to hired.

Cohorts

You don’t learn alone. You climb.

Earn XP each week and you’re placed in a small cohort of peers. Top of the table promotes. Bottom drops. Eight leagues, one honest signal of momentum.
