Inside Codefinity
This isn't a video about Claude. It's Claude. Inside your lesson.
Every course comes with a live AI workspace. Claude reads your files, edits your code, and runs commands — right next to the lesson that explains why.

Live workspace
All project assets land here. You can manage it and run it
One window.
Chat, terminal, files, lesson — no tab-hopping, no setup, no API keys
No API keys, no install, no “Anthropic account required”. It just runs.
Claude can Read, Edit, and Bash inside your workspace. What you build, you keep.
First handful of interactions are free. Paywall only appears after you've seen it work.

Learner stories
Real people. Real results. In their own words.
Verified Codefinity learners — their LinkedIn profiles are linked. No actors, no scripts.
I have really liked the browser-based lessons that allow me to code within the lesson. The RUN button allows me to test the code I write before submitting for a grade.
I have gained a lot of practical and logical thinking skills, along with patience for myself and confidence in myself that I can learn programming. Years ago, I would have never thought that I could learn programming in any way, shape or form, and I was able to obtain these certifications and skills with Codefinity.
The learning was progressive and made it easy to follow along and make progress. I could feel my skills increasing and building on each other as the course went along.
The teaching methodology at Codefinity is excellent, and I particularly appreciate how it has prepared me to handle real-world coding problems. Currently, I am delving into Node.js and eagerly anticipate building full-stack projects that integrate all the knowledge I have gained.
