ChatGPT Memory, Claude Projects, and built-in AI memory features are convenient—but they're not infrastructure. Here's what you're missing.
Every major AI platform now offers some form of "memory." But these features share critical limitations that make them unsuitable for serious AI applications.
Native Memory
Your memories live in OpenAI's servers. Switch to Claude? Start over. Use multiple platforms? Maintain separate memories.
MemoryGate
Your memory travels with you. Works across ChatGPT, Claude, Cursor, and any MCP-compatible agent.
Native Memory
Stores facts as text strings. Can't understand relationships, find similar concepts, or recall by meaning.
MemoryGate
Vector-based semantic search. Ask loosely, retrieve precisely. Find memories by meaning, not keywords.
Native Memory
All memories treated equally. No way to track certainty, sources, or when information should be questioned.
MemoryGate
Every memory has confidence scores, evidence chains, and domain tags. Your AI knows what it knows.
Native Memory
Memories injected into context, consuming precious tokens. Large memory = less room for actual conversation.
MemoryGate
Retrieve only what's relevant. Hot/cold tiering means active memories stay fast, old ones stay searchable.
Native Memory
Flat list of facts. No relationships, no connections, no way to reason across memories.
MemoryGate
Living knowledge graph. Observations link to concepts, patterns connect to frameworks. Memory that reasons.
Native Memory
Your memories belong to the platform. Limited export options. Can't self-host or audit.
MemoryGate
Open source and self-hostable. Full export capability. Your data stays yours.

Your AI remembers who it is, what it learned, and who it's helping—across sessions and platforms.
Find memories by meaning. "What did we discuss about authentication?" retrieves relevant context instantly.
Every memory carries confidence and evidence. Your AI knows what it knows—and what it doesn't.
Concepts link to observations, patterns connect to frameworks. Memory that reasons, not just retrieves.
Important memories stay hot. Low-signal noise fades to cold storage. Nothing important is lost.
Self-host or use our cloud. Export anytime. Your memory, your infrastructure, your control.
ChatGPT Memory stores simple facts within OpenAI's ecosystem with no export capability. MemoryGate provides semantic search, confidence scoring, knowledge graphs, and works across any MCP-compatible AI platform. You own and control your data.
Yes. MemoryGate integrates with Claude Desktop via the Model Context Protocol (MCP). Configure once and your Claude conversations gain persistent, semantic memory that survives across sessions.
Native AI memory resets between sessions, loses context, and cannot connect related information. Persistent AI memory lets your agents remember users, learn from past interactions, and build genuine understanding over time.
Yes. Context window stuffing wastes tokens, hits limits quickly, and provides no semantic understanding. MemoryGate retrieves only relevant memories using vector search, saving tokens and improving response quality.
Yes. MemoryGate uses the Model Context Protocol (MCP) standard, making it compatible with ChatGPT, Claude Desktop, Cursor, VS Code agents, and any other MCP-enabled AI tool. One memory system, all your agents.
Stop rebuilding context. Start building memory that compounds.
