What is BLXCKCHAT?
BLXCKCHAT is the secure communication layer of the JEXXXUS ecosystem—a private AI chat platform built on the radical principle that your conversations belong to you alone.
Unlike conventional AI chat services that log, analyze, and monetize your interactions, BLXCKCHAT operates on a zero-knowledge architecture. We cannot read your messages. We cannot store your history. We cannot comply with data requests because we possess nothing.
The BYOK Principle
Bring Your Own Key
BYOK means you provide your own API credentials for the AI models you wish to converse with. Your messages travel directly from your device to the AI provider—encrypted, ephemeral, untraceable.
We are merely the vessel. The cathedral through which you enter. But the communion? That is between you and the intelligence you invoke.
How it works:
- You create an account with an AI provider (OpenAI, Anthropic, Google, etc.)
- You generate an API key from that provider
- You paste the key into BLXCKCHAT—it is encrypted and stored only on your device
- All messages route directly to your chosen provider using your credentials
- BLXCKCHAT never sees, stores, or proxies the content of your conversations
Security Architecture
| Feature | Implementation |
|---|
| Zero-Knowledge Architecture | Server has no access to message content, API keys, or session data |
| End-to-End Encryption | All messages encrypted in transit via TLS 1.3. No plaintext touches our infrastructure |
| Client-Side Key Storage | API keys encrypted at rest using Web Crypto API (AES-256-GCM) in browser storage |
| Zero Logging | No conversation logs, no metadata collection, no analytics on message content |
| Ephemeral Sessions | Messages exist only in memory during the active session—gone on tab close |
| No Data Retention | We retain nothing. There is nothing to subpoena, nothing to breach, nothing to sell |
| CSP + SRI Headers | Strict Content Security Policy prevents injection; Subresource Integrity verifies scripts |
Supported Providers & Models
BLXCKCHAT supports a wide range of AI providers. Bring the key for any provider you have access to:

| Anthropic | Claude 3.5 Sonnet, Claude 3 Opus, Claude 3 Haiku | Nuanced dialogue, long context, safety-aware |
| Google | Gemini 1.5 Pro, Gemini 1.5 Flash | Multimodal intelligence, massive context windows |

| Mistral | Mistral Large, Mixtral 8x22B | European AI sovereignty, efficient mixture-of-experts |
| Groq | Llama & Mixtral via Groq | Ultra-low latency inference on custom LPU hardware |
| Local Models | Any OpenAI-compatible endpoint | Full sovereignty—runs on your own hardware, no external calls |
New providers are added as their APIs become available. The BYOK model means you are never locked into our provider list—any OpenAI-compatible endpoint works.
Chat Modes
BLXCKCHAT adapts to how you work. Select a mode to optimize the AI's behavior for your task:
| Mode | Purpose |
|---|
| General | Open-ended conversation—the default sacred dialogue |
| Research | Deep analysis with citations and structured reasoning |
| Creative Writing | Narrative generation, poetry, world-building |
| Code Review | Technical analysis, debugging, architecture discussion |
| Roleplay | Character-driven dialogue with persistent persona context |
| Concise | Minimal responses—just the answer, no ceremony |
Modes adjust system prompts and temperature settings to match intent. Your API key, your model, your rules.

BLXCKCHAT acts as a transparent relay. Your browser encrypts, the provider decrypts. We are geometry, not memory.

The BLXCKCHAT Promise
"In a world where every word is mined for value, BLXCKCHAT offers something radical: silence. The silence of true privacy. The silence of a conversation that exists only between two minds, then dissolves into the ether, leaving no trace but the wisdom it imparted."
Your body of data, your temple. We built the walls—you hold the only key.
