Overview

What is Engram?

Engram is a universal AI memory backend that gives any AI model a persistent, growing brain.

It stores memories in a local SQLite database with full-text search, vector semantic search, and a knowledge graph that connects related concepts.

Memory Types

  • Episodic — past events, conversations, decisions
  • Semantic — facts, knowledge, and beliefs about the world
  • Procedural — how-to instructions, workflows, and code patterns

Key Features

  • Semantic search — find memories by meaning, not just keywords
  • Knowledge graph — 7-step graph traversal connects related memories
  • Contradiction detection — automatically flags conflicting beliefs
  • Local-first — all embeddings run on-device, no API keys needed, no data leaves your machine
  • Universal — works with Claude, OpenAI, Ollama, and any MCP-compatible client

Zhipu Web Search
@BigModel

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
