Score: 6.5/10 (Innovation: 7, Technical: 8, Documentation: 5, Utility: 6)

Shivvr is an ephemeral, in-memory semantic embedding service that combines local ONNX-based GTR-T5 embeddings with optional OpenAI embeddings, hybrid FST-BM25 search, per-agent encryption, and a cognitive agent loop with MCP protocol support. Its innovative combination of ephemeral state, crypto-preserving similarity search, and turn-based agent reasoning is interesting for building privacy-focused, transient semantic applications.

Target audience: backend devs, data engineers, ai-ml engineers
