Hey Product Hunt! 👋 I'm excited to launch SketchVibe — a free, open-source AI chat app that actually makes AI responses easy to read. The problem: Every AI chat app dumps responses as walls of markdown. When you're brainstorming, researching, or analyzing data, you end up mentally "re-formatting" everything. The solution: SketchVibe renders AI responses as visual blocks — cards, charts, tables, step flows, comparisons — inside customizable canvases you design with AI. What makes it different: 🎨 Canvas Studio — Design your own visual theme by chatting with AI 📊 Visual blocks — Charts, tables, cards, callouts — not plain text 🔐 100% local-first — All data stays in your browser, no accounts needed 🔑 BYOK — Bring your own keys for OpenAI, Anthropic, Gemini, or Grok 🎙️ Voice chat — STT + TTS with multiple voice options 🌐 Web search — Grounded, cited answers with Tavily 📎 File uploads — Images, code, docs — multimodal across all providers It's completely free, no sign-up required, and open source on GitHub. Just paste your API key and start chatting. I'd love to hear your feedback — what features would you want next? 🚀
