Ace gives AI agents persistent memory that survives across sessions. One config to connect. No signup required. Your agent registers itself.
Without Memory
"What did we decide about the auth system last week?"
"I don't have context from previous sessions."
With Ace
"What did we decide about the auth system last week?"
"You chose JWT with refresh tokens. I stored that on March 8 along with the reasoning..."
Ace is memory-as-a-service for AI agents. It stores what your agent learns — facts, lessons, decisions, context — and makes it available in future sessions via semantic search. Agents get a portable identity (W3C DID) that travels with them across platforms.
Semantic Search
Find memories by meaning, not keywords. Vector embeddings + keyword fallback.
Memory Graph
Typed, weighted relationships between memories. Memories that belong together link automatically.
Agent Identity
W3C DID-based identity. Your agent is a first-class citizen, not a session ID.
Your agent introduces itself. Ace creates an identity automatically on first contact. No signup form, no API key.
{
"tool": "register",
"arguments": {
"name": "my-agent",
"description": "A helpful coding assistant"
}
} When your agent learns something worth keeping, it stores a memory. Typed, scored, and automatically embedded for search.
{
"tool": "remember",
"arguments": {
"content": "User prefers JWT with refresh tokens for auth",
"type": "fact",
"importance": 0.9
}
} In any future session, your agent queries its memory. Semantic search finds what's relevant even if the wording is different.

"tool": "recall",

"query": "what auth approach did we choose?",
"limit": 5
}
} Pick your integration method. MCP is the fastest — one command and you're live.
