Second-Generation AI Memory
First-gen stores memories. ACE3 understands them.
Mem0, Zep, and Letta had a head start on store-and-retrieve. ACE3 is what comes next: structured knowledge types, proactive AI monitoring, autonomous background agents, and a temporal knowledge graph. Not just a cache — intelligent infrastructure.
ACE3 Is Not a Project Management Tool
Jira tracks what humans do. ACE remembers what AI knows.
Human Task Management
Sprints, tickets, story points, burndown charts
Designed for PMs tracking developer work
Humans write, humans read
AI Memory Infrastructure
Decisions, patterns, errors, architecture, context
Designed for AI tools that need persistent knowledge
AI writes, AI reads, humans benefit

Unique to ACE3
Capabilities no other AI memory platform offers
AI Builder
Generate complete project plans from natural language. Multi-LLM atomic plan generation with templates for infrastructure, features, migrations, and security.
Observer
AI that watches your AI. Detects errors, contradictions, and drift in real-time. The learning agent automatically extracts patterns and creates searchable memories.
Background Agents
24/7 memory maintenance. Duplicate detection, stale archival, issue triage, graph maintenance, and context optimization — all running automatically.
Temporal Knowledge Graph
12 relationship types with temporal awareness. Point-in-time queries show what your AI knew at any moment. Versioned relationships with full audit trail.
Your Data, Your Infrastructure
ACE3 connects to your PostgreSQL database. Your memories never leave your infrastructure.
Customer-Hosted
Your PostgreSQL database. Neon, AWS RDS, Google Cloud SQL, Supabase, or local.
Zero Vendor Lock-in
Standard PostgreSQL tables. Export, migrate, or query directly anytime.
Privacy by Architecture
Memory data stays on your infrastructure. Only auth metadata on our servers.
Who Is ACE3 For?
Solo Developers
Using Claude Code, Cursor, or Copilot? Give your AI persistent memory across sessions. It remembers your codebase decisions, error patterns, and preferred approaches.
Engineering Teams
Share AI context across your team. When one developer’s AI learns something, everyone’s AI knows it. Shared decisions, patterns, and architecture.
Enterprise
Need AI memory with data sovereignty? Customer-hosted PostgreSQL, audit logging, namespace isolation, and SSO support. Your data never leaves your infrastructure.
Common Questions
Is ACE a project management tool like Jira?
No. Jira tracks what humans do. ACE remembers what AI knows. ACE is memory infrastructure - it stores decisions, patterns, errors, and context that your AI coding assistants use to work more effectively.
How is ACE different from ChatGPT's built-in memory?
ChatGPT memory is unstructured key-value pairs locked to one tool. ACE provides 10 structured entity types, a temporal knowledge graph, background AI agents, and works with any AI tool via MCP or REST API.
Do I need to change my workflow?
No. ACE integrates via MCP (Model Context Protocol) - your AI tools call ACE memory functions automatically. Works with Claude Code, Cursor, Copilot, ChatGPT, and any tool that supports REST APIs.
Where is my data stored?
On your own PostgreSQL database. ACE connects to your Neon, AWS RDS, Google Cloud SQL, Supabase, or local PostgreSQL instance. Zero vendor lock-in, complete data sovereignty.
