Four layers. One cognitive infrastructure.

Persistent memory, evolving agents, runtime trust, and portable identity — all in one self-hosted platform.

Remembers

Structured memory that survives across sessions, tools, and teams. 10 typed entities, 15 relationship types, temporal knowledge graph.

Available on every plan — including Free.

Evolves

AI Genome Lab — eight behavioural traits that adapt and inherit through every interaction. Fork specialised agents for security, review, or compliance.

Available on Starter and above.

Catches

The Observer watches every AI tool call in real time. Catches contradictions, drift, and risky patterns before they land.

Available on Starter and above.

Travels

Passport — device-bound cryptographic identity. Your agents carry memory, genome, and trust across every AI tool you use.

Available on Starter and above.

The Problem

Every AI conversation starts from zero

"How is auth implemented?"

(asked 50 times)

"What database do we use?"

(context lost every session)

"Why did we choose X over Y?"

(decision forgotten)

ACE3 is cognitive infrastructure for AI agents — persistent memory, behavioural evolution, runtime trust, and device-bound identity. Self-hosted on your PostgreSQL.

Structured Memory That Gets Smarter

10 structured entity types your AI understands. Not task tracking for humans — cognitive infrastructure for AI.

Error History

Debug context that persists. Stack traces, root causes, solutions. Your AI won’t hit the same bug twice.

Architecture Decisions (ADRs)

Why you chose React over Vue. Why PostgreSQL over MongoDB. Your AI follows the rationale, not just the choice.

Session Context

Pick up where you left off. Your AI knows what you were working on, even after closing the terminal.

Coding Standards

Rules your AI applies automatically. Team conventions, linting preferences, naming patterns.

Code Patterns

Reusable solutions your AI remembers. "We solved this before" - and your AI knows exactly how.

Your Data, Your Control

Self-hosted on your PostgreSQL. Neon free tier, Supabase, AWS RDS, or local. Complete privacy.

Built for AI Coding Assistants

Native MCP integration. Your AI calls ACE directly. Works with every plan.

  • 77 MCP tools - memory recall, error tracking, ADRs, graph traversal, agents, observer, genome
  • Full REST API - works with any AI tool
  • Sub-10ms lookups - no latency in your workflow

Connected Codebase Memory

Your AI traverses relationships to find context automatically. Error → root cause → fix → prevention.

15 Relationship Types

implementsreferencessupersedesrelates_tocaused_byresolvesdocumented_independs_onblocksduplicatesvalidatesreproducescontradictsenrichesinforms

Your AI Can Discover

  • "What errors were caused by this architectural choice?"
  • "Find similar bugs and their fixes"
  • "Show patterns used in this codebase"
  • "Trace: error → root cause → solution → prevention"
Example:

"Add OAuth2 + JWT auth to my Next.js app with role-based access"

ACE creates:
  • 3 ADRs (why these choices)
  • 5 architecture components
  • 4 coding standards
  • 2 code patterns
  • All linked in knowledge graph

Bootstrap Your AI's Context

Describe your architecture. ACE creates structured memory your AI assistant can use immediately.

  • Natural language to structured memory
  • Automatic relationship linking
  • Review before saving
  • Works with GPT-4, Claude, or Gemini

Get Started in 5 Commands

Install, login, init, connect, start. Your AI coding assistant now has persistent memory.

AI Genome Lab: Where Memory Becomes Behavior

Eight behavioral traits that evolve through every interaction. Your AI develops a unique behavioral signature for your domain.

  • 8 behavioral traits — Perception, Reasoning, Empathy, Memory, Expression, Adaptation, Regulation, Integration
  • Live evolution — Traits activate and mutate as your AI processes information
  • Agent specialization — Fork agents with domain-specific behavioral biases
  • Full lineage tracking — See exactly how your AI's behavior evolved over time

Behavioral DNA

Nobody designed the eye. Evolution produced it from simple components. We're building the substrate where AI memory evolves into something more.
