**T**emporal **H**ierarchical **O**bject **U**nion & **G**raph **H**ybrid **T**oolkit — a local MCP memory server that gives any LLM a persistent, auditable memory fabric on your own machine.

> OB1 stores your thoughts. Karpathy's wiki compiles your knowledge. **THOUGHT** remembers with provenance, understands relationships, detects contradictions, never forgets what used to be true — and routes every query to the right mathematical structure before touching a single byte of data.

### Status & contributions

**THOUGHT is experimental software.** Expect rough edges, surface changes between minor versions, and the occasional sharp corner — especially in the v0.4 query layer and local-LLM paths. APIs that the README documents are stable enough to build against, but anything described as a "subset" or marked "v0.4+" is still settling.

**The project aims to improve on existing context / memory systems** for LLM agents. The closest comparables are Mem0, Letta/MemGPT, Zep, and Graphiti — each shipped impressive work; THOU…
