Hey HN, I am a student shipping apps in my free time. This is my 4th for the year! Non-fic books and podcasts have been part of my life for years now but I always struggled with remembering what I’ve read or listened to. I wanted it to stick even after years. My notes list grew large but I never really revisited them. That’s why I created GinkgoNotes. You can enter notes you want to recall and leave it to the app to create a personalised (based on spaced repetition) email schedule. That means you’ll get your notes emailed to you a couple of times exactly when you should read them again…

recall▲43I have been bouncing off flashcards because making them by hand has been always a tedious task. Recall runs as an MCP server - you can connect it to Claude or Chatgpt, point your handwritten or typed notes (PDFs, docs, or even a Notion Page), and it writes Q&A cards straight into a deck. You could even ask Claude or Chatgpt to research on a topic and do the same without having the need to make notes. Then you review them with the FSRS spaced repetition algorithm. Built it solo over the last 2 weeks. Stack used: Next.js, Drizzle + Neon, ts-fsrs for scheduling It's a paid product - no card…

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!

When I do real research — reading papers, books, or trying to understand a complex topic — it never happens in one sitting. I explore a bit, get interrupted, come back days later, ask new questions, find new sources, and gradually build understanding. Existing AI tools are great at answering questions once, but they reset context every time. Notes tools preserve text, but not understanding — they don’t help me reconnect ideas, revisit sources, or see how my thinking has evolved. I built Kerns to sit in between. Kerns is an AI research workspace designed for research that unfolds over time.…
