Please avoid inputting highly confidential information.)</p> <h1> Why I'm Building This </h1> <p>Because I wanted it myself.</p> <ul> <li>I want to record daily learning → But no time to write in detail. I struggle with how to write.</li> <li>I want to create a portfolio → But it's too tedious and never gets updated.</li> <li>I want to visualize my growth → But organizing it manually is exhausting.</li> </ul> <p>Don't you think "just 3 lines" is something you can stick with?<br> If those accumulated notes become a portfolio, that's motivation to keep going.</p> <h1> Demo </h1> <p>I built a demo using Vercel's v0 👇</p> <p><a href="https://v0-learn-log-mu.vercel.app/" rel="noopener noreferrer">https://v0-learn-log-mu.vercel.app/</a></p> <p><del><em>Note: This is currently a mock version. AI doesn't actually run—sample output is displayed.</em></del><br> Jan 7th: I've implemented Claude API call function, so you can try note and portfolio auto generation.</p> <h1> Looking for Feedback </h1> <p>I'm currently deciding whether to build this into a full product.</p> <ul> <li>What features would make you want to use this?</li> <li>What looks hard to use?</li> <li>How would you use it?</li> <li>Honestly don't need it?
