Aura: AI-powered, end-to-end encrypted messaging & vault

💬 Maker’s First Comment (Launch Post) Hey Product Hunt! 👋 We built Aura because privacy on the modern web shouldn't mean sacrificing smart protection. Traditional encrypted messengers shield your messages, but they leave you exposed to malicious links, phishing attempts, and account takeovers. Standard AI assistants offer smart security, but usually at the expense of reading your private conversations. Aura bridges that gap. We combined battle-tested, military-grade encryption with an on-device AI sentinel that acts as a passive guardian for your conversations. 🛡️ What makes Aura different? Zero-Knowledge Architecture: Powered by Signal Protocol (Double Ratchet + X3DH) and AES-256-GCM. We store ciphertext only — no keys, no backdoors, no plaintext access ever. On-Device AI Threat Watch: Our passive sentinel analyzes metadata patterns locally to flag phishing, bad links, and suspicious behavior without ever touching your message content. Encrypted Data Vault: Keep private notes, credentials, and files sealed and synced across only your explicitly trusted devices. Disappearing Messages: Flexible self-destruct timers so no digital breadcrumbs or history linger behind. Cross-Platform & Ultra Fast: Built over a global edge network to deliver sub-millisecond speeds on web, desktop, and mobile. 🎁 Try it out! Aura is completely free to start — no credit card, no tracking, no bloat. We’d love to hear your feedback on the AI threat watch and the vault setup. What features would you like to see in our next update? Thanks for checking us out! 🙌
