EverOS

[Adoption verdict] Worth a serious trial if you use Claude Code or Codex heavily for project work; it's one of the few memory plugins with code-level openness. But it's not a one-click cloud service – local maintenance requires technical effort. [What it does] Each conversation is saved into versionable Markdown files; the agent then indexes and retrieves past decisions, bug-fix paths, and specs automatically. Architecturally it goes beyond a RAG wrapper or vector DB: it uses separate layers for indexing, semantic compression, and context injection, with a transparent, auditable design. [Cost & prerequisites] Open-source with no publicly known pricing (all community demos show free local use). You clone the repo and set up the plugin. The prerequisite is comfort with managing your own Markdown knowledge base and understanding the layered design; for light script work the overhead may outweigh the benefit. [Community consensus] Evidence includes deep code reviews by @xetgepete, @AuroraMar1eL, and @Kawsar_Ai, iterative experience reports, plus promotional posts.
