Show HN: Core – open source memory graph for LLMs – shareable, user owned

I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps.

The deeper problem

1. Not portable – context is vendor-locked; nothing travels across tools.

2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance.

3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried.

What we built

- CORE (Context Oriented Relational Engine): An open source, shareable knowledge graph (your memory vault) that lets any LLM (ChatGPT, Cursor, Claude, SOL, etc.) share and query the same persistent context.

- Temporal + relational: Every fact gets a full version history (who, when, why), and nothing is wiped out when you change it—just timestamped and retired.

- Local-first or hosted: Run it offline in Docker, or use our hosted instance. You choose which memories sync and which stay private.

Try it

- Hosted free tier (HN launch): https://core.heysol.ai

- Docs: https://docs.heysol.ai/core/overview

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.
