An open source repo to use your personal context with any agent
Your repo remembers the code. Memex remembers you. An open-source context layer you own: the durable stuff about you and your work, shared across every AI tool. Your own database, your own keys, pennies a month.
An open source repo to use your personal context with any agent launched on November 4, 2026 with 4 votes, #124 of 673 launches that month and more than 50% of that year's launches.
What it does
The durable context about you and your work, like preferences, decisions and background, shouldn't live inside one AI app. Keep it in your own database and let any agent use it. Paste that into any coding agent. It walks you through the setup and does the typing for you. The durable, cross-cutting context that every tool should know, and that no single repo can hold. Your preferences and how you like to work, decisions and the reasons behind them, corrections, people and plans, and stable background on your products and projects. Code-specific context, status updates and to-dos stay in your repo, CLAUDE.md or AGENTS.md . Agents are told to leave them out of Memex. Memex is an MCP server…from predsymod.github.io

Core – open source memory graph for LLMs – shareable, user owned2025 · github.com · ▲112I 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. Demo video:…
