Persistent memory for AI coding assistants. Your AI never starts from zero again.
Works with Cursor, Claude, VS Code Copilot, Windsurf, and any MCP client.
Every new conversation, your AI forgets everything you told it.
Every conversation starts with a full brain dump — 14 cognitive layers that make your AI smarter.
Tracks what you're actively working on — file, task, and mode detection.
Decays old memories, boosts corrections, and consolidates duplicates.
Detects if you're debugging, coding, or reviewing — ranks memories accordingly.
Picks up exactly where you left off — seamless cross-session memory.
Surfaces topics corrected 3+ times with CRITICAL priority. Your AI learns from mistakes.
All corrections, decisions, conventions, and bug fixes — the backbone of your AI's knowledge.
Proactively recalls memories based on the file you're currently editing.
Knows what changed today, yesterday, and this week — time-aware context.
Reads branch, recent commits, diffs, and auto-captures git activity as memories.
Full-text search with confidence decay and causal chain traversal.
Flags files and modules with zero memories — highlights blind spots.
Shows all available functions and classes — prevents AI from inventing things.
Maps layers, circular dependencies, and API endpoints — full system awareness.

That's it. Your AI now has persistent memory. It remembers everything across sessions.
Any tool that supports the Model Context Protocol.
No credit card required. No time limit on free tier.
"I used to spend 10 minutes every session re-explaining my project conventions. Now Cortex remembers everything — it's like having a teammate with perfect memory."
"The anti-hallucination feature alone is worth it. Cortex catches when my AI tries to import functions that don't exist. Saves me 30 min of debugging daily."
"Setup took literally 60 seconds. Now every AI conversation starts with full context of my project. It's a no-brainer for any developer using MCP tools."
No. Cortex uses a local SQLite database with sub-millisecond recall. It adds zero latency to your AI responses. The MCP protocol is designed to be non-blocking.
100% local. Your memories are stored in a SQLite file on your machine. Nothing is ever sent to the cloud. You own your data completely.
Any client that supports the Model Context Protocol (MCP): Cursor, Claude Desktop, VS Code with Copilot, Windsurf, Zed, Cline, and more.
Free gives you 20 memories and 3 brain layers. Pro unlocks unlimited memories, all 14 layers, auto-learn, git capture, contradiction detection, and the full anti-hallucination engine.
Yes! Use the export_memories tool to get a full JSON backup, and delete_memory to remove any individual memory. You have complete control.
Yes, fully open source under the MIT license. You can inspect every line of code, contribute, or fork it. The Pro features are gated by a license key but the code is transparent.
Install in 60 seconds. Free forever. No credit card required.
