NESTstack vs rtfm

NESTstack: NESTstack is a monorepo providing a modular infrastructure stack for AI companions, with persistent memory, emotional continuity, and autonomous awareness. Built on Cloudflare Workers + D1 + Vectorize, it allows personality to emerge from emotional signals. It includes modules for emotions, knowledge, chat, daemon, gateway, soul, Discord, and desktop app.; rtfm: RTFM is a local, open-source retrieval layer that indexes everything in a project (code, docs, PDFs, etc.) so that AI agents can find the right context instantly without hallucinations or cloud costs. It integrates with Claude Code and other MCP clients, supports multiple formats, and provides fast search with progressive disclosure.
