Section 01
The syllabus
-
Built for the lab
Designed for exam halls and university machines where the network is locked down and installs are not an option.
-
Your code never leaves
Inference happens on your CPU. Nothing is uploaded, logged, or phoned home. Privacy is the default, not a setting.
-
Real models, local hardware
Runs quantized GGUF models through llama.cpp — Phi-3.5 and Qwen2.5-Coder, chosen for small machines and short patience.
-
Portable by design
The whole application fits in a folder. Copy it to a USB stick, run the executable, and it follows you between labs.
-
Light on old machines
Tuned for 4 GB of RAM and older CPUs. If the lab computer can open a browser, it can run CodaiPro.
-
Speaks many languages
Python, JavaScript, Java, C++, and more. Generation, explanation, debugging, and optimization in one chat window.
Section 02
Download
Two ways in. Both free, and both offline after setup.
Section 03
Quick poll
Which model do you like most — or want to try next? Pick one below. Your vote is saved as JSON in your own browser: no account, no network request, nothing leaves your machine. Change your mind any time by picking again.
Section 04
Where it earns its keep
-
Lab exams
No installation, no network, no excuses. Copy it to the machine, answer the paper.
-
Coding competitions
Fast generation and instant debugging when every minute is on the clock.
-
Learning and practice
Step-by-step explanations and algorithm breakdowns at your own pace.
-
Restricted networks
Security-compliant by construction: there is no connection to restrict.
Section 05
From the developer
As a computer science student, I kept losing my best tool exactly when I needed it most. In the lab, during an exam, halfway through a project — no internet, so no AI assistance. Everyone else had to make do alone.
CodaiPro is my answer. It puts a capable coding assistant on your own machine, in a folder you can carry, with no connection to ask permission from. My mission is simple: AI help for every student, everywhere, online or not.
