Built a Notebook with a AI assistant that pushes back I got tired of chat bots being too agreeable and custom prompts didn't help from sucking up to me. I built this website which forces you into independent thinking. It has a simple UI interface that helps you pen out your thoughts and AI that only guides your thoughts with few minimal suggestions not answers. It's still in it's alpha and I would love for people to help test it out and provide their thoughts. submitted by /u/Tight-

My first vibe-coded app 🚀 Built with just a few prompts using Claude Code, with full CRUD support. Still amazed at how quickly an idea can turn into a working app with AI-assisted coding. #VibeCoding #ClaudeCode #AI #BuildInPublic

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
