Cross-Platform (Windows, macOS, Linux)
AI Spark — Local Multi-LLM Broadcast, Comparison & Synthesis Suite
AI Spark is an open-source, local multi-model AI desktop orchestrator and comparative web suite. It simultaneously broadcasts single prompts to ChatGPT, Gemini, and DeepSeek running securely in your browser, displays responses side-by-side in a comparative grid, and leverages Claude to synthesize a comprehensive, non-contradictory final answer with zero paid API costs.
Architectural & Engineering Highlights
Concurrent Multi-LLM Broadcast Engine
High-speed asynchronous asyncio pipeline broadcasting your single query simultaneously across ChatGPT, Gemini, and DeepSeek browser tabs with zero serial queuing latency.
Claude Neural Synthesis Core
Gathers generated responses from all three AI models in real time, parses AST Markdown and code blocks, and prompts Claude to formulate a structured, exhaustive, and unified answer without contradictions.
Dual Modes: Instant & Spark DeepThink
Switch seamlessly between Instant Mode (1-on-1 direct conversation with a single model for rapid prototyping) and Spark Mode (full parallel 3-way multi-model broadcast with automatic Claude synthesis).
Universal Multi-Browser CDP Driver
Native support for Brave, Chrome, Edge, Firefox, and Opera. Connects via Chrome DevTools Protocol (CDP :9222) directly to your default browser profile—preserving existing logins, cookies, and extensions.
Chrome Extension Bridge (Manifest V3)
Features a dedicated WebSocket bridge server (ws://127.0.0.1:41243) connecting an unpackable Chrome Extension for setups where direct profile locking is restricted, enabling zero-restart browser attachment.
100% Local Privacy & Multi-Modal Staging
Zero third-party cloud telemetry. Sessions are saved locally in SQLite (chat_history.db) with full search. Multi-modal files (PDFs, images, docs) are automatically distributed to all active model tabs.
Technical Comparison & Efficiency Matrix
How AI Spark compares to manual tab switching and commercial cloud API aggregators.
| Feature & Capability | AI Spark Engine | Manual Multi-Tab Browsing | Cloud API Aggregators |
|---|---|---|---|
| Recurring Subscription Cost | $0.00 (Uses Web Sessions) | $0.00 (High manual effort) | $20 – $100+ / month |
| Simultaneous Query Broadcast | Instant 1-Click Parallel | Manual copy-paste to 4 tabs | API rate-limited calls |
| Multi-Model Response Synthesis | Automated Deep Claude Synthesis | Manual mental cross-check | Basic generic prompt summary |
| Data Privacy & Telemetry | 100% Local FastAPI / Zero Logs | Standard browser privacy | Third-party server logging |
| Multi-Modal File Upload Distribution | Automated CDP Multi-Tab Ingestion | Manual file upload on each tab | Strict token / file size limits |
| Local Chat History & Search | Indexed SQLite Database (chat_history.db) | Scattered across 4 web platforms | Cloud stored history |
