piia-engram vs second-brain-cloudflare

piia-engram: piia-engram is a local-first AI identity layer that stores your profile, preferences, lessons learned, and key decisions as local JSON files. It exposes them through the MCP protocol so that all compatible AI tools (like Claude Code, Codex, and Cursor) read the same identity, eliminating the need to re-explain yourself across sessions, tool switches, or updates.; second-brain-cloudflare: Second Brain is a self-hosted MCP server on Cloudflare Workers that provides a persistent memory layer for AI tools like Claude, ChatGPT, and Cursor. It allows storing, searching, and recalling information across conversations with semantic search and recency bias. Deployable with one click on Cloudflare's free tier.
