Hi Product Hunt! I'm the maker of GPTwiki. Here's why I built it: I've always loved Wikipedia, but I noticed a gap — when you want to learn about something, you often need to piece together information from multiple sources. What if AI could generate a well-structured wiki article from a single question, and that article could grow through community contributions? That's GPTwiki. It combines the best of three worlds: 1. AI-powered content generation — Ask Claude, GPT-4o, or Gemini any question 2. Wikipedia-style knowledge sharing — Every answer becomes a permanent, searchable article 3. Community collaboration — Anyone can continue the conversation to expand articles Some things I'm proud of: - 100,000+ articles already seeded across 15 languages - Users can bring their own API keys (no vendor lock-in) - Fully open source under MIT license - Built with Next.js 16, deployed on Google Cloud Run I'd love to hear your feedback!
