Lumen Chat puts the world's most powerful AI models in your pocket โ€” all in one beautifully designed app. Chat with multiple AI providers, snap photos for instant identification, search the web, build websites, and analyze documents โ€” all powered by cutting-edge artificial intelligence. โ— MULTI-MODEL AI CHAT Unlike apps locked to a single AI, Lumen Chat connects you to multiple leading AI models from different providers. Switch between reasoning models, fast models, and multimodal models with a single tap to find the best answer for every question. โ— AI COUNCIL โ€” INDUSTRY FIRST Can't decide which AI to trust? Summon the AI Council. Your question is sent to multiple AI models simultaneously. Each model responds independently, then a synthesized "Council Verdict" combines the strongest insights into one superior answer. No other app offers this. โ— CAMERA VISION Point your camera at anything โ€” a plant, a math equation, a product label, a painting, food, or text โ€” and get instant AI-powered identification, analysis, and detailed information. โ— DEEP THINKING MODE Activate reasoning mode and watch the AI think step-by-step through complex problems including math, logic, coding challenges, and scientific questions. โ— BUILT-IN WEB SEARCH Search the web and receive AI-summarized answers without leaving the app. No additional accounts required. โ— AI WEBSITE BUILDER Describe any website in plain English and watch AI generate a complete site with HTML, CSS, and JavaScript. Preview it live right in the app, then copy or share the code. โ— DOCUMENT & PDF ANALYSIS Import PDFs, text files, and documents for instant AI-powered analysis, summaries, key point extraction, and question-and-answer sessions. โ— CONVERSATION MANAGEMENT Organize, pin, search, and export your conversations. Share AI responses as formatted text with friends, colleagues, or on social media. โ— PREMIUM DESIGN Crafted with a stunning dark-mode interface, smooth animations, and native iOS components.
