I've been working on https://notebooker.ai if anyone is interested in giving some feedback. I tried to post a Show HN yesterday with details about how I built it, but was auto-flagged and not sure what rules I broke. Everything that I've built on top of open-notebook, like the plugin system for your own "creators" (aka, podcasts, infographics, etc) is at https://github.com/Notebooker-ai plus a Cloudflare Worker AI deployer to play with different models. Been working on it for about six months.

A tool to learn every county in England I wanted to learn the ceremonial counties of England, but could not find a good tool for that, so I vibecoded a quiz tool which turned out to be quite good (certainly better than I expected). It's called UK County Quiz: it shows you a county name and you click where it is on the map. Three modes — Classic (untimed), Timed (20 questions against a 10-second countdown), and Explore (hover over counties to learn names at your own pace). https://andolea

StudyFocus - A study tool that analyses your material and prepares tests for you! Title pretty much says it all. I build what I would consider a perfect study tool for myself, and I use it (almost) every day. It analyzes the PDF, lecture videos, etc. and creates study material, practice problems, shows step-by-step solutions to problems, creates flashcards, and creates tests.

Spun this up in 4 days for work because I didn’t want to give higher schoolers another boring wellness tips handout. Needs more love, particularly the “explore” tab, but crazy how empowering vibe coding is.

Built a bookmarking app you can ask questions It's called Attic. You paste in links, videos or plain text. Later you can ask it things in normal language: "what have I been reading about lately", "what did I save and never open again". Each answer lists the saved items it used, so you can check it. It runs on your own API key (Anthropic, OpenAI or Gemini) Free while I work out what it should be. No card. Would like feedback on where to take this. Is asking questions about your own saved s

I built an AI app that turns any study material into a gamified learning journey Hi everyone! After several months of development, I'm excited to finally launch my project: Odyssa. The idea came from my frustration with reading long PDFs, taking notes manually, and forgetting what I'd learned. Instead of just summarizing content, Odyssa transforms your study material into a complete gamified learning journey powered by AI. You can upload PDFs, documents, and other learni
