CodeLab

A coding lab notebook for Visual Studio, by Dr. Omar Aburub.

Following a tutorial or a course? Save your code after each small change and CodeLab turns it into a short lesson.

• Keeps every version of each file you work on.
• Shows exactly what changed with a clean line-by-line diff.
• Explains the change in four short parts: What changed, Why it matters, Concept to remember and Try this, a one-minute exercise.
• Exports the whole session as a printable web page (save it as PDF from Chrome) or as Markdown.

Bring your own AI

Choose Gemini, Groq, Claude or OpenAI and paste your own API key. New to this? Follow the free Gemini key guide, it takes about two minutes.

Your key stays in Windows Credential Manager on your PC, and your code is sent only to the provider you pick.

Works the way you do

• Snapshot on save for automatic lessons, or press the camera when you're ready.
• Add a note about why you changed something, and the lesson takes it into account.
• Lessons in any language: English, Arabic, French and more.
• Several sessions per solution, Undo for the last lesson, and Try again if a lesson fails.
• A calm, minimal panel that follows your Visual Studio light or dark theme.

Getting started

1. Open View > Other Windows > CodeLab.
2. Click the settings icon, pick a provider and paste your key.
