Replen is a local intelligence layer for AI coding agents that maps your repositories into a knowledge graph, then continuously scores open-source projects against your actual capabilities using semantic matching and a self-tuning feedback loop. It's interesting because it autonomously surfaces high-signal suggestions—like libraries to adopt or algorithms to port—directly inside your AI session, without relying on keyword search or LLM calls for matching.

Target audience: backend devs
