Give your coding agents
memory that persists
Every new session starts from zero — your codebase conventions, architecture decisions, and debugging history, gone. MemNexus gives Claude Code, Cursor, and Copilot persistent context that survives every restart.

Migrating auth from REST to gRPC — schema finalized in PR #47, client stubs left to generate
gRPC schema uses proto3 · buf lint enforced · no streaming RPCs yet
Team uses Zod validation + strict TypeScript, ESLint enforced
See the Difference
Same task. Completely different experience.
Back-and-forth to establish context every session
Instant context from your coding history
Sound familiar?
Every developer knows these frustrations
“You've explained your coding style 47 times”
“You can't find that conversation where you solved the exact same bug”
“Your AI gives generic answers, not ones tailored to your workflow”
“Every new project starts from zero”
Six patterns of AI memory failure — documented with solutions. See the full picture →

What MemNexus Does
Three things your coding agent can't do without MemNexus
Searchable Decision History
Why you chose PostgreSQL over MongoDB. Which auth library you rejected and why. The debugging session that traced a race condition to your caching layer. Every technical decision is extracted, indexed, and retrievable by meaning — not just keywords.
Learns Your Team's Conventions
Your strict TypeScript config. Your Zod validation patterns. Your preference for async/await over .then() chains. MemNexus extracts these from your conversations and applies them automatically — so your agent stops suggesting approaches your team already rejected.
Git-Aware Memory (CommitContext)
Every git commit captures what changed — MemNexus captures why. The architectural reasoning, the tradeoffs considered, the bugs discovered. Six months from now, git blame tells you who changed a line. MemNexus tells you the full story.
Works however you work
Why Not Just Use Built-In Memory?
ChatGPT Memory, Cursor context, and Copilot workspace indexing are useful starting points -- but they keep your knowledge trapped in one tool. Learn the architectural difference.
Cross-Tool
Built-in memory
Locked to one tool. ChatGPT memory only works in ChatGPT. Cursor context only works in Cursor.
MemNexus
Works across Claude Code, Cursor, Copilot, Windsurf, and any dev tool that supports MCP or REST APIs. Switch tools without losing context.
Persistent
Built-in memory
Memory resets between sessions, disappears when you switch machines, and gets wiped by tool updates.
MemNexus
Survives session resets, tool switches, and machine changes. Your knowledge graph lives in the cloud, accessible from anywhere.
Learns Over Time
Built-in memory
A flat list of facts with no relationships. Can't connect that your Redis caching decision relates to your scaling strategy.
MemNexus
Builds a knowledge graph that links decisions, patterns, and context. Understands relationships between your memories, not just individual facts.
How It Works
From install to persistent memory in under 5 minutes
Install and Connect
npm install the CLI, run mx setup, and it auto-detects your tools — Claude Code, Cursor, Windsurf, Copilot. One command writes the MCP config. Your workflow doesn't change.
Code With Your Agent
Discuss architecture, debug a failing test, choose between libraries. MemNexus extracts the decisions and reasoning from your conversations — why you chose Zod over io-ts, what caused that flaky integration test, which caching strategy you ruled out.
Context Carries Forward
Next session, your agent already knows your stack, your conventions, and what you tried last week. It retrieves relevant context before you type your first message — across tools, projects, and team members.
