Project
NexusChat
A decentralized web application that blends AI-powered assistance with user-owned data, offering intelligent chat, note-taking, and storage capabilities — all backed by blockchain privacy and security.
About This Project
Where AI Meets Data Sovereignty
NexusChat is more than a chatbot — it’s a decentralized space for learning, thinking, and storing knowledge. Every message and note is encrypted, owned by you, and stored on-chain — with your wallet as the key.
Tech Stack
Built with Modern Web Technologies
AI Chat Across Any Topic
From writing code to answering life’s questions, NexusChat uses powerful AI models like ChatGPT to help you learn, create, and solve problems in real-time — with zero data compromise.
User-Owned Data on the Blockchain
Every message, note, or folder is securely encrypted and stored as a Sui blockchain object — fully owned and managed by you, not by us.
No Accounts, Just Your Wallet
Log in with your Sui-compatible wallet. No usernames, no passwords, no centralized databases — only cryptographic access and session-based control.

Roadmap
What’s Next for NexusChat?
- Hybrid Storage: Cloud & Blockchain
Implement a hybrid data system where encrypted content is stored off-chain on a decentralized cloud (e.g. IPFS), while proofs and metadata remain on-chain. This balances cost, scalability, and decentralization without sacrificing ownership.
- User-Selectable AI Models
Expand AI flexibility by allowing users to choose from multiple integrated AI providers — including OpenAI (GPT), Google Gemini, Anthropic Claude, or open-source alternatives — based on performance, privacy, or cost preferences. Users can select their preferred model in a settings panel before starting each chat.
