ReTap - AI Spaced Repetition System
Spaced repetition with AI-powered answer checking
What it does
ReTap is a spaced repetition system where AI checks your answers. Unlike Anki, where you self-grade, ReTap uses AI to evaluate responses and give feedback. Key features: AI answer checking, automatic scheduling based on assessment, programming cards with syntax highlighting for 10+ languages, and the SM-2 algorithm. Ideal for developers learning languages, algorithms, and technical concepts, with AI feedback instead of self-assessment.

Owl is built a spaced repetition app. We built it for ourselves mostly because we were unhappy with Anki from a UX perspective, and are now releasing it to everybody else. It is super tiny, but - we think - also pretty good. You can add your own decks manually, or generate them from a PDF (think academic papers, which is how I use that feature) or a prompt. There are no emails except study reminders (when there are cards to study). You can also use our "AI tutor" to review cards conversationally. Looking forward to your feedback!

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
