In Part 12 you made your first API call. In Part 13 you build something real. A working meeting notes summariser in Python, a walkthrough of every decision in the code, and the pattern behind it that you will use for everything else.
The API sounds technical. It does not have to be. This post walks you through your first Claude API call step by step, explains what every line of code does, and shows you why even non-developers should understand how it works.
en months of using both seriously, across real work, not benchmarks. Here is an honest account of where Claude wins, where ChatGPT wins, and the question that actually matters when choosing between them.
Claude can be confidently, fluently wrong. This is the honest post about hallucinations, which situations carry the most risk, and the simple habits that protect you without making Claude unusable.
Claude Projects gives you a persistent workspace with standing instructions and permanent files. Here is what it actually is, how to set one up, and why it changes how often you reach for the tool.
A system prompt tells Claude everything it needs to know before you type a single word. Here is what goes in one, a real example you can adapt, and how to write yours without starting from scratch.
Everyone writes about using Claude for emails. This post is about the quieter use cases that actually make a difference at work, and what to check with your organisation before you start.
There is a difference between knowing something and understanding it. This is how I use Claude as a learning tool that actually builds real understanding, not just answers to questions.
Most people use Claude as a ghostwriter and wonder why their content sounds hollow. There is a better way. Here is how to use Claude to make your own writing sharper without losing your voice.
I used Claude for everything across a full working week and kept notes on what actually worked. Honest account of the wins, the disappointments, and the two use cases I almost skipped that turned out to be the most valuable.
