kai vs Sephera

kai: Kai is a semantic infrastructure for code change that understands code meaning—functions, dependencies, behavior impact—not just line diffs. It powers precise CI, context-aware IDEs, and verifiable AI coding agents.; Sephera: Sephera is a local-first Rust CLI that combines repository metrics and deterministic context export. It provides fast line counting, deterministic context bundles with AST compression, and a built-in MCP server for AI agent integration. It focuses on giving reliable structural signals and focused context for LLMs and humans.
