CharmOS · {C(H+A)RM}

**The first open-source framework that manages both your human contacts AND your AI agents as first-class relationships, on top of a personal "second brain", driven by one decision loop: RDR.**

C(H+A)RM = **C**RM for **H**umans **+ A**gents **R**elationship **M**anagement. RDR = **R**ecall to **D**eep **R**esearch to synthesis. The loop that turns memory into decisions.

What this is

Three things most people keep in separate silos, unified into one open framework:

1. Second Brain to a private, local-first knowledge base (markdown vault) with semantic recall (embeddings + reranker), an always-on per-turn memory ledger, and a graph/associative recall layer.
2. C(H+A)RM to a relationship layer that treats people and AI agents alike as contacts you maintain: notes, history, warm intros, follow-ups.
3. RDR to the method that ties them together: Recall what you already know, run Deep Research to fill the gaps, then synthesize into a Decision Memo before you act.

Why it is different

The ecosystem is rich but siloed:

Space	Examples	What they miss
Personal knowledge (PKM)	AFFiNE, Logseq, Khoj, Quivr	no agent memory, no contacts
Agent / LLM memory	Mem0, Letta, Cognee, Graphiti	no personal vault, no human CRM
Personal CRM	Monica, Twenty	ignore AI agents entirely

**No tool spans personal notes to agent memory to human CRM, and none prescribe a structured decision loop.** That intersection, plus RDR, is the whole point.

Who it is for

Founders, researchers, and operators who want a durable "digital twin" of how they think and who they know, that they fully own, can repair themselves, and can grow over years.
