SYNAPSEEDThe Thinking Layer Between You and the LLM

High-Performance Semantic AI Middleware — AST intelligence, DLP security, and architectural analysis in a single Rust binary.

AST Semantic Engine

Tree-sitter based multi-language parsing. Your LLM sees symbols and relationships, not raw text.

Real-time secret detection and redaction via Aho-Corasick. Every byte is scanned before leaving the process.

Concept-based code search. Find "authentication logic" even when the code says "verify_credentials".

Churn analysis, co-change patterns, and semantic commit classification. Understand why code looks the way it does.

Dependency graph analysis, coupling metrics, and cycle detection with graded health scores (A-F).

Ingest OpenTelemetry traces, map spans to source symbols, and visualize runtime hotspots directly on the code graph.

Ask a natural-language question, get an orchestrated response from all subsystems in a single call.

Background cargo check with live diagnostics and auto-applicable quick fixes.

⚡

Pure Rust, no network calls, no cloud dependencies. Sub-10ms response times for most operations.

Reproducible SCR evaluation with JSONL question suites. Track search MRR, precision, and recall metrics.

Autonomous code maintenance. Finds unused deps and fixes clippy warnings.

Analyze compiled binaries (ELF/Mach-O/PE) to understand behavior without source code.
