Hey everyone, I need to confess something I used to be a bit embarrassed about: I’m a full-stack developer, but I was constantly Googling basic syntax. Things like JavaScript's .reduce() method, Python list comprehensions, or even CSS Flexbox properties. I knew the concepts, but my fingers just couldn't seem to remember the code. In this age of AI, where we can generate entire applications with a single prompt, it felt almost ridiculous to be stuck on these fundamentals. It turns out, I wasn't alone. After sharing my frustration on Reddit and X, I realized tons of developers—from juniors to seniors—felt the same way.
That's when I decided to build a solution for myself, and for all of us. I created CodeRepeat (coderepeat.dev), a web app designed to turn coding knowledge into pure muscle memory. The idea is simple and heavily inspired by learning tools like Anki. It uses a Spaced Repetition System (SRS) to help you practice typing out code snippets. You create a "deck" (like "Python Fundamentals" or "Webdev Fundamentals"), and the app presents you with code to type. Based on how difficult you rate each snippet, the SRS algorithm schedules it for practice again in the future—sooner for the tough ones, later for the easy ones. It’s not about learning from scratch; it’s about making the code you already know flow effortlessly.
I’ve been the first and most dedicated user of CodeRepeat for a few weeks now, and the change has been incredible. I spend way less time breaking my focus to look up syntax I should know by heart. My coding feels more fluid, and I can stay in the zone for longer, which has been a massive boost to my productivity and confidence. I built this because I was tired of feeling like my own brain was a bottleneck, and it has genuinely helped me become a more efficient developer.
Now, I'm sharing it with the community because I believe it can help you too. I would be incredibly grateful if you could give CodeRepeat a try and let me know what you think. The app is free to get started with, so you can see if it works for you. I'm looking for honest, constructive feedback to make it better. What do you find yourself constantly looking up? Do you think a tool like this could help you? Let me know in the comments below!
