The first true Zero Data Retention (ZDR) AI app — built to save you money, protect your privacy, and help you get more done. Aura brings ChatGPT, Claude, Gemini, and Grok into one unified chat that works together to give you the single best answer. Get better results, streamline your workflow, and stop juggling multiple subscriptions. Aura includes built-in privacy protections and an advanced Tool Router that goes far beyond standard AI tools. Designed to be clear and human-centered, Aura uses a proprietary orchestration system to synthesize responses from multiple frontier models into one unified answer. Turn on Research Mode and the models deliberate against each other before answering, surfacing disagreement instead of hiding it. Read the synthesized answer, expand each model’s individual output, or switch to a single model at any time, all in one interface. TURN CONVERSATIONS INTO REAL ACTIONS WITH 1000+ APPS, BUILT-IN AUTOMATION, AND A BROWSER AGENT FOR NEARLY ANY WEB APP Aura turns conversations into real actions. With Aura’s AI automation builder, simply say what you need and Aura builds it for you directly inside the chat. With more than 1000 apps, you can send emails, manage your store, organize tasks, draft documents, build presentations, design video promotions, and more — all from one chat. There is no complex setup. Aura wires everything together for you, and you can manage or update your automations at any time. If an app is not available through the Tool Router, Aura’s Browser Agent can control and automate nearly any web app. AURA VOICE On the go and need to send a last-minute proposal? Aura can do it. On a bike ride and need dinner plans sorted before you get home? Handled. Just speak naturally. Aura routes your request through your connected apps or takes the browser route for anything more advanced. Aura Voice is real-time and hands-free, with native interruption so you can talk over it and redirect mid-sentence. PRIVACY FIRST — YOUR DATA STAYS YOURS Zero Data Retention means AI providers never store or train on your content. Your data is encrypted in transit and at rest with AES-256-GCM. Per-message ZDR receipts let you verify exactly how every answer was handled. No data is sold. No tracking. No compromises. Your privacy is our number one priority. FREE UNLIMITED MODE — OPT IN Want unlimited chat at no cost? Switch on Unlimited, a free and clearly labeled route with unlimited real-time web search, voice, and image generation, subject to fair use. Unlimited Mode operates outside ZDR, so prompts on this route may be logged by the provider. It is entirely opt-in, always visibly labeled, and never mixed into your ZDR, Project, or Tool Router chats. ADAPTIVE INTELLIGENCE Aura learns your communication style and preferences over time. Get personalized responses that improve the more you use Aura. Custom instructions and global rules help shape every conversation. POWERFUL FEATURES Generate stunning images and videos with cutting-edge models in AI Studio. Have voice conversations with natural-sounding AI and live web search. Upload documents and images for analysis. Organize your work with Projects, cloud sync, and file management. Search across all your conversations instantly. PLANS FOR EVERY WORKFLOW Free to start. Essential, Pro, and Elite tiers available as you scale. Free Unlimited Mode is available on every plan. DESIGNED FOR YOU Beautiful dark and light themes. A smooth, native iOS experience. Works seamlessly across desktop, iPhone, and iPad. You may read more about our terms of service here: https://aura.youniverse.ai/terms
