• Show HN: Rubi – A knowledge graph that cuts how much Claude Code re-reads · score 6.8

  Rubi is a knowledge graph and context manager for AI coding agents like Claude Code, designed to reduce token costs by minimizing context re-reading and improving project navigation. It combines techniques like BM25, PageRank, and Personalized PageRank to build a searchable memory of code structure and decisions, with reported cost reductions from real usage studies.

• Show HN: Audistill – A local knowledge base from audio, YouTube and podcasts · score 6.0

  Audistill is a macOS desktop app that transcribes audio and video locally using NVIDIA Parakeet, then uses an LLM via OpenRouter to distill transcripts into structured summaries and a searchable knowledge base. It combines local speech-to-text with bring-your-own-key LLM summarization, keeping audio on-device while offering privacy-conscious knowledge management.

• Show HN: Node research browser for knowledge networking · score 4.7

  NODE Research Browser is a desktop application that combines multi-pane browsing, auto-crawling, and LLM integration to create a visual, time-machine-like research trail. It addresses the fragmentation of online research by allowing users to save and revisit contextual browsing sessions, though it lacks public code, documentation, and a clear monetization path.
