Show HN: Build and deploy AI agents from your own data in under 60 seconds

Hi HN,I built Bot The Builder to solve a recurring problem I kept facing while building chatbots for clients: every time, I had to rebuild the same RAG stack, embed the same knowledge base, and deploy from scratch—even for small use cases.So I created a tool that lets you build and deploy AI agents from your own data (PDFs, docs, URLs, text) in under 60 seconds — no code required. You can embed the agent in any website or access it via API.### Why I built it: - Most “AI chatbot builders” are eit

Show HN: Tiled Words, a daily puzzle inspired by board games and crosswords

A week ago I launched Tiled Words, my own unique spin on the daily word puzzle genre.Tiled Words merges tile-placing board game mechanics with crosswords. You rotate and rearrange tiles to find clues and rebuild a broken crossword. Every day there's a new themed puzzle for you to solve.The game is web based: the graphics are SVGs, animations are powered by CSS, and Vue/Nuxt are used to power templating, reactivity, and routing. Most of the complex logic lives in TypeScript modules. The

Building them using their template repository was surprisingly painful: every time you make a change on your React widget, you need to rerun the entire build pipeline to get fresh JS and CSS assets. The dev feedback loop was pretty terrible.That’s why I built a TypeScript starter that gets you up and running in under a minute. Clone, npm install, npm run
