🔒 Zero Server Logs, Military-Grade E2EE
Every message, photo, file, and call is secured by End-to-End Encryption (E2EE) powered by the X25519 Diffie-Hellman key exchange. The server acts merely as a routing pathway; the moment a message is delivered, it is permanently wiped from the server queue. Built on a strict 'Zero-Knowledge' architecture, not even server administrators can access your chats.

🤖 On-Device AI (Offline Local AI)
Powered by a cutting-edge Small Language Model (SLM), our AI runs exclusively on your device's local processing power—no internet required. Real-time translation, grammar correction, chat summarization, and image analysis are processed locally without touching an external cloud. You can confidently utilize AI even for conversations containing highly confidential business secrets.

📂 Offline AI Document Box (RAG) & Knowledge Graph
Upload your work documents (PDF, TXT, etc.), and the on-device AI will comprehend the context to provide deep, offline Q&A. Analyze complex documents further through Knowledge Graph synchronization. Review contract clauses and summarize report insights securely with zero risk of data leakage.

🕵️ Zero Personal Data, Complete Anonymous Signup
We demand zero personal information—no phone numbers, no emails, no real names. Utilizing mathematical Proof of Work (PoW) to block bots, you can generate an anonymous account using just a 12-word mnemonic seed phrase. This is your sole key to recover your account; because it is never stored on a server, your identity remains completely protected.

🌐 Web Version Support — No Installation Needed
Simply open a web browser on your PC or tablet to start chatting instantly. No software installation is required, yet you get the exact same robust E2EE security as the mobile app. A single logout ensures absolutely no digital footprint is left behind on shared devices.

💬 Effortless Usability, Powerful Security
No complex setups needed. Use it naturally just like any everyday messenger. Texting, photos, videos, files, voice messages, and location sharing—enjoy all standard features while every single piece of data is automatically E2EE encrypted. Group chats are equally protected with automatic symmetric key encryption.

🗑️ Total Control Over Your Data
Use 'Delete for Everyone' to wipe messages from both sides with no time limits, or edit them in real time within 10 minutes of sending. Set a timer with the 'Disappearing Messages' feature, and your texts will automatically vanish from both devices after the designated time.

📞 High-Quality P2P Voice & AR Video Calls
Experience crystal-clear, WebRTC-powered peer-to-peer (P2P) voice and video calls protected by E2EE. Add fun to your conversations by applying 'Cosplay Stickers' and real-time color filters during video calls.

🔄 Secure Backup
Your chat histories can be safely backed up and restored in a fully encrypted state. Even when switching devices, all it takes is your mnemonic seed phrase and backup file to safely restore your precious conversations.
