Show HN: Easyfaq.io – Free SEO-Optimized FAQ Page Generator (LLM-Friendly) https://ift.tt/7SbfaGs

Show HN: Easyfaq.io – Free SEO-Optimized FAQ Page Generator (LLM-Friendly) Hi HN I built EasyFAQ, a free tool that helps you generate and embed SEO-friendly FAQ pages. It’s aimed at making structured content easy to publish, especially for small sites, blogs, and landing pages. The generated FAQs include proper schema markup (JSON-LD), so they’re optimized for Google’s rich results and easier for large language models like ChatGPT to interpret accurately. I made this after noticing how much well-structured FAQs can improve site clarity and search visibility. The tool requires no login, and you can export or embed the generated FAQs directly. Would love feedback from the HN community — especially around UX, SEO usefulness, or other feature ideas. link: https://easyfaq.io Thanks! July 21, 2025 at 12:21AM

Show HN: The missing link of a bookstore's tech stack https://ift.tt/tbyhLPS

Show HN: The missing link of a bookstore's tech stack Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand I have a very exciting roadmap that I'm not ready to fully reveal, but it's all based on books. I'm building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I'm hoping to change that. I have a blog post that lays out my vision here: https://ift.tt/YhK4kbX The current iteration is like "data engineering as a service for books." A book is a powerful thing. I'm hoping to give a bookstore everything they need to sell books online. Inventory, e-commerce, marketing, etc. It's a crowded market but I've had fun making the bookselling app that I believe should exist. If you know any booksellers, please let them know about this! I'm onboarding my first customer right now and the biggest bottleneck is the other bookselling software providers, despite my intention to collaborate instead of compete. It's frustrating to wait for two weeks for a point of sale provider to setup an integration. It's almost like they don't care about their customers. Some providers even require ethernet cables for their software...still partying like it's 1999. Perfect for early-adopter booksellers frustrated with current tech who understand the power of automation. I'm currently looking for funding so I can focus on this full-time. My biggest problem right now is time (aka money) because I have to sell my time to make rent etc, and can't focus on this project like I need to. I've gotten good validation from booksellers and other technically savvy folks in the industry (I've heard from two different companies that they've considered building something like this), so I believe I have something valuable. I'm not interested in funding from somebody who doesn't share my love for books or doesn't support my mission: help people use technology to promote literature. I believe that literature is one of humanity’s most prized creations, and we can use technology as a tool to keep this gift alive. Please email me at sam@bookhead.net if you know of booksellers who might want to be an early adopter, or know of any funding opportunities that might be a good fit. https://bookhead.net/ July 21, 2025 at 12:19AM

Show HN: Transform passive YouTube watching into active learning https://ift.tt/EJYolz5

Show HN: Transform passive YouTube watching into active learning I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask. I built Notetube to fix this by layering organizational tools with AI to create a proper learning system: Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear ...plus additional features like timestamped note-taking, but I'll keep this brief. Quick signup via Google OAuth for a smooth onboarding experience.
