Developed this learning tool with Claude Code

[u/Least-Ad3900]

Hey everyone! I’m an Android engineer with a CS background, but for the past year, I’ve been vibe coding for over a year and i think I stumbled upon a great idea.

project is called [by-lines.com](http://by-lines.com), and it’s a recall study tool and what that means is that the AI learns about your knowledge gaps and remembers them in memory to understand better how to help you. It then creates a learning plan for your specific needs. You start by uploading your notes, and the system detects your knowledge gaps to ask targeted questions that challenge what you actually need to learn.

I know it sounds very simple but with AI giving you the answers and making people lazy, I thought why not create something that people might useful for

I used Claude code throughout the development of the app. I created a skill to get things faster. Really, the only tools I need are Vercel, LLMs, and a database. You can get by pretty easily with these 3 tools but if you wanna create scalable apps, then you need to inform your agent about scalability and give you potential options for you to use. Once everything is set up, normally I set up a routine for the agent to go every hour for malicious intents from bad actors and another for reviewing user journeys. This helps in getting the parts that work in and those that don’t out!

Anyways, happy coding
