Hi,
There are 3 major differences between Zep and CORE 1. Market: Zep is B2B focused, CORE indvidual users 2. Portablity: Zep is locked to their platform , CORE works across claude, cursor, windsurf 3. Architecture: Zep is Temporal based vs CORE is Reified + Temporal based graph
What this means:
Zep remembers what happened when CORE remembers what happened when + why we should believe it + how facts relate
Example: You say "I love Thai food" → Later: "Actually, I hate Thai food"
Zep: "You hate Thai food" (old preference vanishes) CORE: "You currently hate Thai food. This contradicts your earlier statement from [date/source]. The change came from your correction today."
Bottom line: CORE provides full explainability and audit trails that Zep cannot.
Graphiti is free and open source. It's MCP server works with any MCP client, from Cursor to Claude, too...
Graphiti MCP has tens of thousands of users. They deploy it to their desktops, servers, you name it. And for many different use cases: B2B, B2C, and personal use.
