We build a tool called Loomal.ai , wanted to get feedback from the community if you think its helpful or unnecessary?

Do you think AI Agents need an identity?

Are you giving your agents names and IDs, or keeping them strictly ephemeral? I’d love to hear from anyone building in this space.

Show HN: Knowbotic – Upload notes. Get quizzes. Master anything

DannyHeng — Wed, 21 Jan 2026 05:15:39 +0000

Hey HN! We're excited to share Knowbotic, something we built after failing way too many exams despite "studying" for hours. Our problem: We'd spend entire weekends highlighting textbooks and re-reading notes, then bomb the test on Monday. Turns out we weren't actually learning—just moving our eyes across pages and feeling productive. What changed everything: We discovered that testing yourself (active recall) is 8x more effective than passive reading. But creating practice questions manually? Soul-crushingly tedious. So we built Knowbotic. Snap a photo of your textbook page, upload lecture PDFs, or paste any text. The AI reads it and instantly generates practice questions. Then it quizzes you, adapts to what you're struggling with, and uses spaced repetition to cement things in long-term memory. Works on literally any topic: Medical school anatomy, bar exam prep, learning Mandarin, CFA certifications, high school chemistry, random Wikipedia rabbit holes—if you can study it, Knowbotic can quiz you on it. It's completely free for learners. No trials, no paywalls, no "unlock premium features" nonsense. Cool stuff it does:

Generates questions from messy handwritten notes (our handwriting is terrible, still works) Creates personalized study schedules based on your available time Builds study communities where you can share quizzes and challenge friends Tracks exactly which concepts you're weak on instead of wasting time on what you already know

We launched 3 weeks ago and we've already hit 100+ users—all found organically. People are using it for everything from USMLE prep to learning guitar theory, which has been incredibly motivating to see. We've been using it ourselves and actually retained information for the first time in our lives. Now we want to see if it helps others. We'd love your brutal feedback: What would make you actually use this? What's missing? How do you currently study new material without falling asleep? Try it: https://knowbotic.app
