Cortex vs zettelforge

Q: Which is better, Cortex or zettelforge?

By GitHub stars, Cortex has more community adoption, but the best choice depends on your specific use case.

Cortex: Cortex is an MCP server that gives Claude Code persistent memory inspired by neuroscience. It automatically captures, consolidates, and surfaces relevant context, achieving state-of-the-art retrieval benchmarks across multiple datasets.; zettelforge: ZettelForge provides persistent memory for AI agents with automatic entity extraction, knowledge graph construction, and STIX ontology. It supports offline operation with no API keys or cloud dependencies. It features alias resolution, blended retrieval, and memory evolution for cyber threat intelligence.
